|“|| "You're probably wondering why I'm out here, when I could be nestled at home with a book... And that's because I'm sick of seeing people that I care about wheeled past the nurse's station on a gurney. All of you are out here, risking your lives, and it's about time that I do something, too."|
"...In my experience, when tracking homicidal supernaturals, it's best to be quiet.

- The title is a reference to the relics discussed in the episode, which are objects of the Wild Hunt's victims that are left behind as a result of the conservation of mass-- since the total mass of any isolated system remains constant, it's impossible for the Wild Hunt to completely erase every piece of a person's existence.
- Malia Tate and Chris Argent referenced several facts about coyotes, such as the fact that they are nocturnal, they eat their young, and the smell of blood after a kill can send them into a frenzy.
- It is revealed that the Ghost Riders can "ride lightning," essentially teleporting where they want to go through the storms that they conjure. As a result, they can use this ability to bypass Mountain Ash barriers, making no location completely safe from them.
- Mason Hewitt figured out that the McCall Pack can predict the Ghost Riders' arrival by monitoring the K-index, a scale used by meteorologists to measure thunderstorm activity. According to Mason, Beacon Hills has experienced roughly 5,000 lightning strikes per thunderstorm in the last three months, and that an average storm has about 1,000. This seems to indicate that the Wild Hunt has been in Beacon Hills at least since the end of Season 5.
- Natalie Martin revealed that she has known Claudia Stilinski since high school.
- It is also revealed that Claudia's maiden name is Gajos.
- It is implied that the Wild Hunt has the ability to manipulate a person's emotions on a large scale, as evidenced by the fact that the players on the lacrosse teams became aggressive and violent toward each others, which fits what Alan Deaton said about the Wild Hunt being attracted to war and mayhem in Superposition.
