In Teen Wolf, Banshees are special human women who have the supernatural power to sense and predict when someone is about to die. As a result, they are considered harbingers of death and are often referred to as the "Wailing Women" due to the fact that they unconsciously scream to announce when someone has died, usually those killed by supernatural forces.
These women predict death through premonitions, which can be auditory, visual, or both, depending on the power level of the Banshee in question. When a Banshee has a premonition, the sounds and sights they perceive indicate various factors that will either lead to or directly cause the death of someone in their vicinity, which are usually people harmed by the supernatural or someone the Banshee knows. However, these premonitions are not always literal and can require a certain amount of interpretation. Additionally, since the future is always in flux, a death that a Banshee has predicted may not come to pass if the events or cause of the death can be averted using the knowledge gained from the Banshee's premonition. This can be a very useful power for Banshees who are members of a pack, such as Lydia Martin, as it gives them a team of people to help them prevent the foretold deaths.
Known Banshees in the series include Lydia Martin, Lorraine Martin, and Meredith Walker, though it has been implied that there have been other Banshees in Beacon Hills as well, such as the one Sheriff Stilinski met several years prior to the start of the series who predicted the death of his wife, Claudia Stilinski. Another Banshee, Lenore, has been revealed to live in the "ghost town' of Canaan, a town whose entire population had been captured by the Ghost Riders of the Wild Hunt; the trauma of watching her fellow citizens be taken caused her to unleash her powers in the form of a Banshee aura, permeating the town and giving her unprecedented levels of control over everything in its borders, to the point where she even created a ghostly manifestation of her dead son through whom she can use her powers.
However, Lydia has been referred to as an exceptionally powerful Banshee, and as such, she is the one whose powers have been explored the most in the series. Her Banshee nature was triggered after she was bitten by Peter Hale in the Season 1 episode Formality, which activated her supernatural powers; it has been implied that these powers would not have manifested until after she turned eighteen, if at all, had she not been bitten. Once Lydia recovered from the attack, she began going into fugue states during which she would walk or drive to the location of a recently-deceased body, such as the Darach sacrifices and Deadpool murder victims she found in Season 3 and Season 4, respectively. This can also extend to the locations of a person who is about to die as well, as she was unconsciously drawn to Derek Hale's loft during the Deadpool so she could wail for his impending death, though it ultimately did not permanently come to pass.
In Season 3, Lydia was finally identified as a Banshee by Jennifer Blake, who seemed very shocked by this discovery. Because Lydia now knows what she is, she has had an easier time learning to understand and interpret the premonitions she receives, especially after she met fellow Banshee Meredith Walker, who has helped her learn to use some powers she did not know she had, such as the ability to use her voice as a weapon. As she has learned more about her powers, she has become more powerful as well, with her premonitions evolving from being purely auditory to both auditory and visual. She has also gained a slight degree of control over her fugue states, where she can remain at least somewhat consciously aware of what she's doing rather than just going into a full trance, finding a body, and having no idea why or how she got there.
Banshee Physiology Edit
Banshees are human in appearance, and, unlike most supernatural creatures, they do not possess the power to shapeshift. They also do not have superhuman physical attributes such as super strength or accelerated healing, which gives them the same form of mortality as a regular human as well. Chris Argent has implied that this is because Banshees are not actually supernatural creatures who are controlled by the moon or other mystical forces; instead, they are humans with access to the supernatural, allowing the mystical forces to flow through them and utilize them in the form of their supernatural powers rather than being ruled by those forces, like werewolves and Hellhounds. This could be why each Banshee introduced in the series has not had exactly the same power set; while some powers (such as the ability to sense and experience premonitions of a person's death, clairaudience, the ability to utilize a Banshee wail, and a connection to other harbingers of death) appear to be common among most or all Banshees, other powers (like divination, telepathy, supernatural intuition, psychokinesis, and astral premonitions) are unique to certain individuals, suggesting that each Banshee uses the supernatural forces flowing through her in different ways.
While Banshees have been said to have highly enhanced senses of hearing, this trait is not like the enhanced hearing of supernatural shapeshifters such as werewolves or Werecoyotes, whose sense of hearing are tied to their physical enhancements and allows them to simply hear from farther distances and at lower volumes like their canine counterparts. Banshees, on the other hand, do not seem to have the ability to hear physical sounds in this way; rather, they have the ability of clairaudience, with their ears seemingly tuned to supernatural frequencies, allowing their powers to convert those frequencies into auditory premonitions to help them predict deaths.
Banshees are immune to most supernatural phenomena, possibly as a result of not being truly supernatural but still utilizing its forces. For example, Banshees can handle Mountain Ash like any other human, Druid, or Chimera, and it cannot be used to trap them or block them entry from an area as it would shapeshifters. Additionally, Banshees are immune to the bite of an Alpha werewolf and will not be transformed into a werewolf if they are bitten, though they can have a negative reaction to the bite that is similar to a powerful allergic reaction caused by their body rejecting the mystical effects of the bite; Lydia experienced these side effects after she was bitten by Peter Hale and required hospitalization as a result. They will also not be paralyzed if they are exposed to the venom of a Kanima.
The Banshee trait is known to be inherited by a female in their bloodline; in the case of Lydia Martin, she is believed to have gained her Banshee nature from her paternal grandmother Lorraine Martin. It has been implied that their supernatural powers will be activated upon reaching adulthood in most Banshees, though extremely traumatic events can trigger these nascent abilities at an earlier age. For example, Lydia being viciously attacked by an Alpha werewolf triggered her Banshee heritage and caused her to activate her powers at age sixteen, and Meredith Walker also seemed to have gained her powers while she was still in high school, suggesting that she, too, experienced a traumatic event that triggered her abilities earlier than normal, though this has yet to be explicitly confirmed.
Powers and Abilities Edit
Banshees on the series have demonstrated a wide range of powers, which seems to suggest that, while some powers are common among Banshees, they still each use the supernatural energy that flows through them in different ways, causing them to have unique power sets. However, many of these powers can also be taught by one Banshee to another, suggesting that there is potential for a Banshee to have every power. The powers Banshees have demonstrated thus far in the series include the following:
- Death Sense: As harbingers of death, Banshees can sense when someone has died or is about to die. This is usually accompanied by a trance-like state that draws the Banshee to the location of someone who has recently died or who is near-death, though, with experience and training, the Banshee can learn to remain somewhat conscious during this event. For example, almost immediately after her powers were activated, Lydia Martin walked naked from the hospital to the Hale House ruins where Peter Hale had been killed and buried, during her first Banshee fugue state, and was in the woods for nearly two whole days walking around in a trance with little memory of what she was doing. However, in later months, Lydia has been able to consciously direct the people she is with toward a body without going into a full trance. This power has only been demonstrated by Lydia, but it is implied to be a power that all Banshees possess as harbingers of death.
- Clairaudience The ears of a Banshee are naturally tuned to levels of the universe that only they can hear. This gives them an ability to discern details of a person's death (or impending death) through the sounds they can perceive which no one else can. These sounds can include voices (such as whispering or screaming), gunshots, electricity, buzzing, growling, fighting, etc. This power is possessed by Lydia Martin, Meredith Walker, Lorraine Martin, and Lenore.
- Premonitions: Banshees possess the power to experience premonitions that allow them to sense a person's death, which usually allow them to discern how a person dies, where they die, and/or what will cause the death in the first place. This power is most often used as an extension of their power of clairaudience, as the supernatural phenomena that they can sense with their enhanced hearing can take the form of auditory premonitions of an impending death; for example, Lydia was able to foresee Scott McCall's impending death after she had an auditory premonition involving wolves growling and fighting each other and heard Scott telling Liam Dunbar that he couldn't let Liam kill him. She has also received clues as to others who are in danger, such as when she heard crackling electricity all day before William Barrow captured Kira Yukimura and forced her to activate her Kitsune electrokinesis. However, as a Banshee's powers grow, their premonitions evolve from being purely auditory to being visual as well, making it easier for them to interpret what their premonition is trying to tell them. This power is possessed by Lydia Martin, Meredith Walker, Lorraine Martin, and Lenore. Lydia's premonitions are not always literal and can often be up for interpretation, especially given the fact that the premonitions do not typically include every single detail of a person's death. For example, Lydia's premonition of the Desert Wolf killing Malia Tate showed Malia hiding in her former coyote den in the Beacon Hills Preserve as the Desert Wolf approached her, while in reality, the the battle between the Malia and Corinne actually happened at Fort Jewett Army Base.
- Astral Premonitions: In some cases, a Banshee's power of premonition can advance to the point where they can astral project themselves into their visual premonitions, allowing them to pause and examine the details of the vision as well as interact within it. This aspect of the power has only been used so far by Lydia Martin; the first time she used it, her powers had been amplified through trephination, and she was able to astral project herself into a memory of the death of Theo Raeken's sister eight years earlier. Though the effects of her trephination were reversed by Alan Deaton, her powers have evolved naturally to this point once again; recently, Lydia touched a mirror and astral projected herself into a memory of Canaan in 1987, when the Wild Hunt captured everyone in the town of Canaan except for Lenore, a fellow Banshee. She was even able to physically touch Lenore and affect her with her Banshee wail.
- Divination: Banshees are often mistaken for and compared to psychics, due in part to their ability to use various forms of divination as a tool to gain information about the death and danger they are foretelling. This power is possessed by Lydia Martin, Meredith Walker, and, unsuccessfully, by Lorraine Martin when she desperately tried to figure out how she predicted her wife Maddy's death. There are a wide variety of means through which a Banshee can use divination, many of which also involve the use of their other powers, such as clairaudience. The forms of divination used by Banshees on the series include:
- Sound Divination: Using their power of clairaudience, some Banshees can divine for information by using sound vibrations to trigger her ability to perceive supernatural energy. Lydia frequently uses this ability during supernatural events, such as when she plucked on strings to determine that Stiles was dreaming about Eichen House, when she dropped a handful of bullet casings onto a metal table to hear Derek Hale's screams to learn he was captured by the Calavera Family, and when she used the blank record in the record player at the Martin Lake House's soundproof study to divine the first codeword to the Deadpool. Meredith Walker has also used this ability to learn more about the Nogitsune's plans by listening to the vibrations from the piano strings she was plucking.
- Psychometry: Some Banshees have the ability to discern information about a person's death by making physical contact with an object belonging to the person in question. Lydia is the only Banshee shown to successfully use this power; she first attempted psychometry by holding onto Alan Deaton's keys to the animal clinic, and has since used it to help determine who had captured Derek Hale by touching the Calavera Family's bullet casings, trigger a premonition of Liam's future fight with Scott by touching a table in the library that the two would soon smash, and experience an astral premonition of Lenore's memory of April 8, 1987 just by touching a mirror in the girls locker room at school. She was also able to determine that the Turners were not dead due to the fact that she was unable to get a premonition from touching their car's steering wheel.
- Automatic Writing: Some Banshees are able to gain information by going into a trance-like state and writing or typing. Lydia is the only Banshee to successfully use this power; she used it for the first time when she unconsciously drew the Nemeton while zoned out in class as a hint to her conscious self that the Darach's ritual involved the Nemeton's power. She also used it to tell her conscious self that two of the three Philosopher sacrifices had been completed by drawing a five-fold knot in chalk on the blackboard and writing "2" inside one of the knots. During the Deadpool, Lydia unconsciously wrote the Deadpool computer code in her math notes, which, when one of the cipher keys ("ALLISON") was learned by Lydia through Sound Divination, unlocked the first portion of the list; she would later use automatic writing to discover the third and final cipher key by going into a mild trance and typing "DEREK" into the password box. She consciously used automatic writing to determine who was missing from her memories (as well as Scott McCall and Malia Tate's memories) when she wrote "STILES" in large letters, with each letter formed from the word "MISCHIEF," which she scrawled in tiny writing hundreds of times.
- Harbinger Connection: All Banshees possess an almost psychic or telepathic connection, which they can use to communicate with one another, regardless of how far away they are. However, this is an advanced Banshee power that needs to be consciously activated to use it; it is easier to utilize this ability if the Banshees in question already have an established relationship, such as being friends or allies. The harbinger connection has been frequently used by Meredith Walker and Lydia Martin in order to communicate with each other when they can't be physically in the same place. For example, Meredith used it to locate Lydia when she was captured by the Nogitsune, and they both used it to hang out in each other's minds while they were both trapped in a catatonic state in Eichen House; this power allowed Meredith to teach Lydia how to use her voice as a weapon so she could attempt to escape the facility and save her friends. Lydia also somehow found a connection to Lenore, even from a considerable distance away, as it allowed Lydia to have an astral premonition of one of Lenore's memories. Additionally, at least some Banshees seem to have a similar connection with Hellhounds, who are also harbingers of death and who share some of the powers that Banshees have, such premonitions and being drawn to recently-deceased bodies. This has been demonstrated by Lydia and a Hellhound named Jordan Parrish, who share both a supernatural and a romantic connection that allows them to locate each other in emergency situations, along with being able to communicate important messages to each other regarding an impending death; for example, Lydia unconsciously appeared in Parrish's mind after he had been attacked by Belasko and urged him to hold on until help arrived, and she did the same thing after she had become catatonic to warn him of her current status and the fact that Noah Stilinski was near death. However, this connection between Banshees and Hellhounds is still being explored, and the limits of its use are still unknown.
- Banshee Wail: A Banshee's most important and valuable power is their voice, which they can use to produce various effects when wailing or screaming. This is a power that all Banshees possess, though the different aspects of this power often need to be consciously learned before their use.
- Death Announcement: When a Banshee has either received a premonition that indicates that someone has died or will die shortly, or when they have just come out of a fugue state to find that they have located a recently-deceased body, a Banshee will scream at the top of her voice as both a sort of lament for the dead and as an alert to others that a death has occurred. This is almost always an unconscious reaction to death and not something that the Banshee can actively control.
- Premonition Enhancement: A Banshee's scream can also be used to clear out ambient noises from their auditory channels so that they can focus only on the auditory aspects of the premonition they are receiving. For example, when Lydia was trying to figure out where William Barrow took Kira Yukimura, she felt so overwhelmed by all the noise she was hearing that she inadvertently screamed; afterward, all of the other noises had been drowned out, leaving only the buzzing of electricity in the premonition she was receiving and causing her to realize that Barrow had taken her to an electric substation.
- Concussive Scream: The most powerful use of a Banshee's scream or wail is as an offensive weapon, though this, too, is an advanced Banshee power that often (but not always) requires experience and training to use. When a Banshee's wail is given both focus and direction, it can produce so much power and force that it can shatter bulletproof glass, overload electronics, shatter skulls and eardrums, and even create concussive blasts strong enough to throw grown men across a room. Meredith used this ability to throw Lydia down a hallway to demonstrate the strength of the power and how important it was for Lydia to learn how to use it herself. After being trained by Meredith, Lydia used this ability during her first attempt to break out of Eichen House, causing light bulbs to explode from inside Eichen House all the way to Fort Jewett, before using this power several more times during her attempted escape to defend herself against the guards, forcefully throwing them backward against walls to knock them out; she also used this power to defend herself against Sebastien Valet, minimizing the injuries she received in the process. Lenore, a Banshee living in the "ghost town" of Canaan, was able to use this power without training to disorient Scott McCall and Malia Tate and to throw Lydia backward across the room. This power can be focused further by the Banshee channeling their scream through their hands to push people and other objects backward. While her abilities were amplified by trephination, Lydia's concussive scream was powerful enough to fatally shatter Gabriel Valack's skull, though it is unknown if she retains her scream at this powerful of a level now that the effects of the trephination have been reversed. However, Banshee does not need to emit a full scream for their voice to affect their environment; simply speaking in a highly emotional state, regardless of the volume and pitch, can cause objects to shake and disorient people around them, especially if said Banshee is powerful or experienced enough. Lydia was able to use this aspect to turn the resurrected Sebastien Valet back into Mason Hewitt, whom his spirit was possessing at the time, and Lenore used it to shake all of the furniture and objects in her house when she had an emotional outburst.
- Supernatural Immunity: Since Banshees are humans who access the supernatural rather than fully supernatural creatures who are ruled by mystical forces, Banshees are immune to the effects of many supernatural phenomena. A bite from an Alpha Werewolf will neither kill them nor turn them, provided the wounds from the bite aren't fatal; this was demonstrated when Peter Hale bit Lydia in Season 1, which did nothing but activate her latent Banshee abilities. Likewise, Kanima venom will not paralyze Banshees or otherwise have an effect on them whatsoever, as evidenced when Lydia unknowingly ate a piece of rock candy covered in Jackson Whittemore's venom and suffered no negative consequences from the exposure. Also, Banshees can wield rowan wood and mountain ash like any normal human and are unaffected by barriers made of it, which would weaken and trap any other truly supernatural creature. Interestingly enough, Lydia was shown to be immune to the effects of Lenore's Banshee aura, though she was still affected by the concussive blast created by her scream.
- Telepathy: It appears that at least some Banshees possess a form of telepathy, which has been demonstrated by Meredith Walker on two occasions. The first was when she was hospitalized several years prior to the start of the series and was put in the same room as Peter Hale, who was still comatose after being gravely burned in the Hale House Fire. Since werewolves remain conscious even when in comas due to their enhanced healing abilities, he was unable to do anything but think about how angry he was about the fire, and his thoughts somehow found the same "wavelength" as Meredith's, allowing her to hear every single thought running through his head as though he was talking right into her ear. She demonstrated telepathy again right after Scott McCall had ceased performing the Alpha memory-manipulation ritual on her, as she had requested he do so in order for Scott to see how much pain Lydia was in through their shared harbinger connection. After Scott removed the claws from her neck and broke their connection, Meredith telepathically whispered, "Save her," to him in his mind, suggesting that she can telepathically communicate with others who are not Banshees.
- Banshee Aura: It appears that some Banshees possess the ability to imbue their environment with an aura that allows them to have unprecedented control over it as well as giving them the power to affect other non-Banshees through it. This power has only been demonstrated by Lenore, a Banshee who has lived in the ghost town of Canaan since 1987. It is possible that the immense grief Lenore felt as a result of her son Caleb's death was compounded by the trauma of watching every one of her town's citizens being captured by the Wild Hunt while also being spared by them caused her to have such a powerful mental breakdown that her Banshee power was unleashed upon Canaan, causing everything within its borders to be infused with her supernatural energy. This seemed to have only become stronger as a result of Lenore being alone for three decades and not fully processing that so much time had passed. Despite her thirty years of solitude, Lenore had a great level of control over the aura, which she could use in a variety of ways.
- Hallucination Induction: One aspect of a Banshee aura is the ability to cause non-Banshees (even shapeshifters such as Werewolves and Werecoyotes) to have extremely vivid visual and auditory hallucinations. This was demonstrated upon Lydia, Scott McCall and Malia Tate's arrival to Canaan; soon after, Scott and Malia started having vivid and horrific hallucinations-- Scott envisioned his mother, Melissa McCall, with a bite taken out of her skull like the other victims of Garrett Douglas in Beacon Hills, while Malia envisioned her adoptive mother Evelyn and her adoptive younger sister Kylie laying dead on the ground while Theo Raeken appeared and shot her in the stomach. It is possible that the hallucinations forced upon Scott and Malia were premonitions of sorts, since Theo was released from his underground prison that same day, and Melissa has been helping Chris Argent investigate the deaths of victims who died of the same injuries she was shown to have.
- Apparition Projection: Another aspect of the Banshee aura is the ability to create apparitions. Lenore unconsciously used this power to create a ghostly manifestation of her dead son, Caleb, who had drowned in the mid-late 1980s; Caleb appeared both as a young boy in good health and a drowned boy with blue lips. Caleb seemed to exist as a result of the Lenore's Banshee aura, as there are several moments when Caleb speaks where his voice is undercut with Lenore's voice. The apparition of Caleb had a connection to Lenore, allowing her to use her powers to manipulate the Banshee aura through him; he also seemed to have some degree of sentience, as he possessed his own memories of his life and could sense what his mother wanted or felt. It can be argued that Lenore's Banshee power had been operating on a subconscious level and that Caleb was a projection of Lenore's overwhelming desire to see her son again, allowing this projection to manipulate the Banshee Aura and force this effect on Scott and Malia. It should be noted that while Lenore believes that the Ghost Riders brought her son back at the cost of the rest of the townspeople they captured, but there is no proof to support that, making it more likely that her power created Caleb without her knowledge, since she seemingly had no idea that she was even a Banshee until Lydia identified her as one.
- Psychokinesis: Through her Banshee aura, Lenore was able to manipulate the objects in her environment through sheer force of will. This was demonstrated when she caused all of the doors in her home to slam shut on their own, locking Scott, Malia, and Lydia inside. It should be noted that Lenore also caused the front door and the window glass to become so strong that Scott and Malia could not break through it; it is unknown if this was the result of a density-manipulation aspect of the power, or if she could nullify the supernatural powers of other beings. Lenore was also able to turn on a carousel from quite a distance away and cause the lights to flicker, suggesting that this power also included the ability to manipulate electricity.
- Supernatural Sensitivity: Banshees, as conduits of supernatural forces, can sense, seek out, and identify its energy, though how they are able to do this varies among individuals. For example, Meredith is able to sense the supernatural identities of the creatures in her vicinity, as she was able to identify every single supernatural creature in Beacon Hills and put them on the Deadpool. Lydia, on the other hand, is extremely sensitive to supernatural energy; when at the Glen Capri Motel and Camp Oak Creek, both locations where hundreds of people have died violent deaths, Lydia was overwhelmed by the whispers and screams of the dead. Similarly, Lydia was able to feel the Banshee aura that Lenore had created within Canaan while still remaining immune to its effects.
Banshees are still physically human, and as a result, they share the same weakness of mortality, making them vulnerable to injury, illness, and death just as any other human. Because they possess enhanced senses of hearing, they can also be harmed by extremely loud or high-pitched noises; this was evidenced when Meredith was seriously injured after listening to the "Banshee record" with headphones at Lorraine Martin's lake house, and when Meredith's Banshee-wailed so loudly that she caused Lydia's ear to bleed, despite the fact that she was with the regular human Stiles Stilinski, who was not injured by the scream. Banshees are also susceptible to the psychological turmoil as a result of the trauma involved with constantly being surrounded by death, whether it is having premonitions of a death or stumbling upon the body of someone who has been brutally murdered. Since the supernatural world is still a secret to the majority of humans, Banshees are typically mistaken for being mentally ill, since they can see and hear things that very few people can and often behave strangely as a result of the passive aspects of their powers; this puts them at risk of being institutionalized by family members, as Lorraine Martin, Meredith Walker and, briefly, Lydia Martin have all spent time in Eichen House.
Known Banshees Edit
Lydia was just an average teenage girl who reigned as Queen Bee of Beacon Hills High School until she was viciously attacked and bitten by Peter Hale in Season 1's penultimate episode Formality. After this attack, she was hospitalized due to the severity of her wounds and puzzled all of her healthcare providers when her body began to violently fight against the effects of the bite. However, once she fought through the process, her Banshee nature, inherited from her paternal grandmother, was activated, and she began experiencing the effects of her new powers almost immediately. She had a visual premonition of Peter's burned arm reaching through the bathtub drain before fleeing the hospital, still naked from her shower, and entered a fugue state that drew her to the Hale House ruins where Peter was buried under the floorboards of the house.
She struggled to figure out what was happening to her throughout Season 2 and most of Season 3, when she officially joined the McCall Pack and helped them protect the town. She became even more frustrated by not knowing what she was when she began actively wailing for the dead, continued to be unconsciously drawn to the recently killed victims of Jennifer Blake, and had various premonitions she couldn't understand. However, when Jennifer, who was revealed to be the Darach who was violently sacrificing various humans to give herself more power, attempted to kill Lydia for knowing too much about her plans, Lydia wailed, both out of fear and as an alarm that she was about to die, causing Jennifer, who was shocked by this development, to reveal what Lydia truly was-- a Banshee, also known as the Wailing Woman. She was ultimately saved from being killed by Sheriff Stilinski and Scott McCall, and continued to try to learn more about her supernatural identity and how to control her powers.
In Season 4, since she was able to predict the deaths of Beacon Hills citizens, particularly if they were caused by the supernatural, she was put on the Deadpool hit-list for $20 million, the second-highest value aside from her Alpha, Scott, who was valued at $25 million. This was presumably due to the fact that she could predict when the people on the Deadpool would be killed and was protected by a powerful and unique pack. Her abilities allowed her to both unlock all three parts of the hit-list, but also figure out that the Benefactor was her friend and fellow Banshee, Meredith Walker, who was acting on orders she received from Peter Hale while they were hospitalized years earlier.
In Season 5, Lydia's powers continued to develop and evolve, giving her a connection with a Hellhound, Jordan Parrish, and making her a target of Theo Raeken, who sought to add her to his new pack, and Gabriel Valack, who sought to use her abilities to finally defeat the Dread Doctors once and for all. She was able to survive the trephination procedure on her that amplified her abilities to unstable limits, and was taught by Meredith to use her Banshee scream as an offensive weapons, making her even more powerful. It was this power that also allowed the McCall Pack to defeat the Beast of Gevaudan and save her friend Mason Hewitt from being consumed by it.
Meredith was introduced in the series in Season 3B when Stiles Stilinski checked himself into Eichen House, where she was a fellow patient. He overheard her talking on the phone, where she was referencing the supernatural, but did not realize that she was also a Banshee until later in the season. When she sensed that her fellow Banshee, Lydia Martin, had been captured by the Nogitsune, Meredith broke out of Eichen House to help the McCall Pack find her.
Meredith's connection to Lydia continued throughout Season 4, when she broke out of Eichen House again upon sensing that Lydia needed her help to crack the second portion of the Deadpool hit-list code. However, when she was too anxious to help them figure out the third part of the list, it became clear that she was associated with the Benefactor in some way. Despite this, the McCall Pack didn't realize that Meredith was the Benefactor until after Jordan Parrish was forced to kill the orderly, Brunski, to keep him from killing Stiles and Lydia. She later revealed that she got the idea from Peter Hale while they were hospitalized together and she telepathically overheard his plans to start a Deadpool in order to raze the supernatural community of Beacon Hills and start over by creating shapeshifters himself. Meredith later admitted that too many innocent people had died because of supernaturals like herself, and that it was when she heard Lydia Banshee-wail for Allison Argent's death that she decided it was the right time to start the Deadpool.
She made up for her past mistakes in Season 5, when she not only helped Lydia learn how to use her scream as an offensive weapon in order to break out of Eichen House and save her friends, but also allowed Scott McCall to perform the Alpha memory-manipulation ritual on her so that she could show him how badly Lydia was suffering through their Banshee connection and also give him instructions on how to save her life. She remains in a near-catatonic state to this day, only able to actively communicate with others using her Banshee abilities.
Lorraine was the paternal grandmother of Lydia Martin and the person from whom she inherited her Banshee heritage. She gained her Banshee abilities later in life, which first manifested as auditory premonitions of an impending thunderstorm that got so loud she was forced to wail in order to drown out the noise. However, since it was a clear and sunny day, she ignored the premonition, which she ultimately felt was a mistake when she returned home to find that her wife, Maddy, had drowned while boating on the lake at the Martin Lake House.
Realizing that she had predicted Maddy's death, Lorraine became determined to figure out what she was and how her powers worked, turning her focus to pseudoscientific theories and scientists, seeking out help from psychics and mediums, and searching for other people with similar powers. It was during this search that she found Meredith Walker at Eichen House and decided to bring her to the lake house, where she had recently converted the study into a sound-proofed room with a special record player that produced vibrations that a Banshee could use to divine information. It was during this visit that Meredith was seriously injured as a result of listening to the record with headphones at a loud volume, causing her hospitalization where she would meet Peter Hale and learn about the Deadpool.
Lorraine was also a computer programmer and wrote a special code that was ultimately hijacked by Meredith and an Eichen House orderly, Brunski, to create the Deadpool hit-list. Shortly before Lorraine's death in the early 2000s, she had a Banshee premonition that manifested as her unconsciously writing a computer code on a scrap of paper that contained the names of a dozen people who had been killed by Brunski, an "Angel of Death" who was killing those of his patients who he believed needed their suffering to be relieved through death. Included on the list was Lorraine herself, who was ultimately killed by Brunski after he realized she had figured out what he had been doing. She also seemed to have predicted that her granddaughter, Lydia, would become a Banshee and would get into trouble with the Deadpool, and left her a jar of Mountain Ash inside the lake house's boat house, which was made of rowan wood and thus could serve as a protected hide-out from supernatural threats.
Lenore is a powerful Banshee who lives in the ghost town of Canaan. Her powers seemingly became active during or prior to the mid-late 1980s, as the fact that she stated "This isn't real!" when the Ghost Riders began capturing her fellow citizens indicates that she had been having premonitions for some time. In 1976, she had a son named Caleb, who ultimately drowned to death in 1985 under unknown circumstances. In 1987, she was witness to the horrors of the Wild Hunt when the Ghost Riders appeared at the Canaan Day celebration on April 8th, taking every citizen of the town except for her, presumably due to her Banshee nature.
The trauma of this event and the subsequent mental breakdown seems to have caused her to scream so loudly that she imbued the town with her supernatural energy, giving her control over everything within the towns borders. She unknowingly created a ghostly apparition of her son in the process, which was the only being to keep her company over the twenty-six years; she was so absorbed in life with her seemingly-resurrected son that she let dust cover the mirrors and lost track of time, not realizing that nearly three decades had passed until Scott McCall, Malia Tate, and Lydia Martin visited Canaan under the instruction of their friend Stiles Stilinski, who, like the townspeople of Canaan, had been taken captive by the Ghost Riders and was erased from existence. Despite all that her powers had created, Lenore was unaware of her Banshee heritage until Lydia informed her of it, and though she was originally intent to make Scott, Malia and Lydia stay with her and Caleb forever, Lydia managed to beg Lenore to let them go, reminding her that their own hometown was facing a similar fate and that Lydia would be left alone with no equivalent to Caleb to keep her company. However, when Lydia invited Lenore to leave Canaan with them, she insisted that she couldn't leave Caleb, implying that his apparition would be unable to leave the town.
- Banshees were the fourth being with supernatural powers to be introduced in the Teen Wolf series, after Werewolves, Kanimas, and Druids (including Darachs).
