|“|| "Do you...Do you still?"|
"I do. I do still love you. I do, I do still love you."
Jackson and Lydia had been dating since before the start of the series and were seen by most students at Beacon Hills High School as the popular couple at the top of the school social ladder. Jackson and Lydia seemed to be at least a moderately stable couple; however, there were underlying issues between the two that did damage their relationship. This began with Jackson's need to be the best at everything he tried, his cocky and egocentric attitude, as well as the fact that he occasionally blamed Lydia when something went wrong with him.
In addition to the personal issues that Jackson had, Lydia also had her own problems in the relationship; this included the fact that she had to conceal and hide her true intelligence as a result of Jackson's inferiority complex, causing her to act more ditzy and dumb, while at the same time Lydia seemed to only stay loyal to Jackson as long as he was the best at lacrosse and seen as the most popular jock in school.
In Wolf's Bane, when Jackson found out that Scott McCall was a Werewolf, he coveted the new superhuman powers that Scott possessed and set his sights on becoming one himself. In pursuit of this goal, Jackson proceeded to break-up with Lydia via text, with the intention of "removing the dead weight from his life" in preparation for his transformation. Although Lydia tried to shrug it off as something that didn't bother her, it was clear that she was very hurt by Jackson's actions. The two weren't seen interacting until the school dance, with their respective dates (Allison Argent in Jackson's case and Stiles Stilinski in Lydia's case) and it was clear that the two were not on the best of terms. However, this did not stop Jackson from saving Lydia's life after she was attacked and bitten by then-Alpha Werewolf Peter Hale, an act for which Lydia was immensely grateful despite Jackson's cruel behavior toward her after the fact.
In Season 2, Jackson and Lydia were both suspected to be the new reptilian shapeshifter terrorizing Beacon Hills and killing numerous twenty-four-year-old former Beacon Hills High School students, though it was eventually revealed that Jackson was the creature. Meanwhile, Lydia was suffering the side-effects of her mind being haunted by Peter Hale's spirit and the awakening of her own supernatural powers from his Bite. When Jackson started to become aware that he was being controlled by a Kanima Master who was also a fellow classmate, he tried to distance himself from Lydia to protect her. However, it was ultimately Lydia who saved him by calling out his first name with her voice and giving him back the key to his house that he gave her months earlier, which acted as a symbol of their relationship. Not only did this bond bring Jackson back to life after he was killed by Derek Hale his recently-resurrected uncle Peter, but he also came back, not as a Kanima, but as the Werewolf he was always meant to be. Due to the significant amount of attention his deaths and resurrection caused in the town, Jackson and his family moved to London, England, causing Lydia and Jackson to end their relationship for good, though they seemed to do so on good terms.
