|“||Jer, you should get home. Stay inside. Klaus isn't going to stop until he gets all those coffins back. He's not done with you.||”|
At first, both of them seemed to hate each other with a passion, as they were both were rivals for Vicki Donovan's affection, and they were both in different social circles at school; Jeremy was a sophomore who was known to be a punk/druggie, while Tyler was a popular football player and a junior. Tyler generally preferred to ignore Jeremy, though Jeremy frequently confronted and antagonized Tyler to provoke him because he was unhappy about how Tyler treated Vicki. This typically ended in a fight between the two, because while Jeremy was often the person to start the fight, Tyler's hot-headed aggression (later learned to be caused by his werewolf heritage) would usually cause him to snap during these confrontations. However, as time went on and the two were both dragged into the supernatural drama in Mystic Falls, the two became allies and eventually close friends and housemates.
Throughout The Vampire Diaries Series
In The Return, Tyler was sitting alone and drinking in his father's office during his memorial service at the Lockwood Mansion when Jeremy walked in to join him. Jeremy apologized for the loss of his father, and the two bonded over the fact that both of their fathers were dead and seemed to have come to an uneasy truce until Tyler's uncle Mason walked in and caught them sharing liquor in a flask. Mason then sent Jeremy away before taking the flask and drinking out of it himself.
In Kill or Be Killed, Tyler was at the Mystic Grill, texting Sarah and Aimee when Jeremy approached Tyler's table to ask him how he was doing after his father's death. Tyler snapped that he was fine, but when Jeremy just sighed and turned to walk away, Tyler apologized for being rude before inviting Jeremy, Sarah, and Aimee to his house to get drunk, as his mother and uncle weren't going to be there. Later, at the Lockwood Mansion, Tyler, Jeremy, Sarah and Aimee were all having fun and getting drunk when the girls started looking at Jeremy's drawings in his sketchbook, which were all of werewolves. Tyler, unnerved by Jeremy's sketches after just having learned about how he carries the werewolf gene, lured Jeremy into his father's office under the guise of looking at his own sketches before choking him against the wall and asking him why he was drawing wolves. Jeremy admitted that he knew that his family were werewolves and lied that it was because he had read about werewolves in his ancestor John Gilbert's journals and made the connection when Matt was attacked by a "wolf" after Mason had arrived to town. Tyler calmed down after hearing this explanation and confessed that while werewolves ran in his family and that Mason was one, he wasn't, because the curse has to be triggered by the person killing someone, whether accidentally or intentionally.
Tyler also informed him that Mason was looking for a moonstone that belonged to Richard, and showed him the stone that he had found in his dad's office, admitting that he didn't want to give it to Mason because Mason wouldn't tell him the truth about why he wanted it. Suddenly, the girls came in and interrupted them by stealing the moonstone from them and running around the house with it. Tyler, not wanting to lose the heirloom, insisted that Sarah needed to give it back, but she was too drunk and continued to keep it away from him. Eventually, Tyler tried to yank the stone out of her hands, which resulted in him accidentally pushing Sarah down the stairs. She tumbled down the staircase and hit her head hard on the floor, and both Jeremy and Tyler were terrified that Tyler had killed her and triggered his curse. Fortunately, Sarah was just briefly knocked out, and she playfully whined at him for pushing her down the stairs.
In Plan B, Tyler and Jeremy were helping set up for the Masquerade Ball at the Lockwood Mansion that night, where Jeremy, who was sent by Damon to get the moonstone, claimed that he had researched the stone online out of boredom and learned that it was part of some Aztec legend. When he asked Tyler if he could see the stone again to see if it was the same one, Tyler informed him that he ended up giving it to Mason, because he was really scared when he thought he had killed Sarah and that he wanted nothing to do with werewolves, legends, or curses.
In The New Deal, Jeremy and Tyler were in the woods, where the two of them were drinking beer and shooting cans with Alaric's cross-bow. Jeremy asked Tyler what the point of this activity was, but Tyler explained that since they had both been dumped by their girlfriends (Caroline and Bonnie, respectively), their solution was to "get drunk and shoot stuff." Jeremy brought up the fact that Alaric would kill them both if he knew they were using his cross-bow, so Tyler asked him what the deal with Alaric and Jeremy was. Jeremy admitted that Alaric was essentially his guardian before instructing Tyler to get out of the way before he got shot. Tyler reminded him that since he was a hybrid, there was no way that Jeremy could actually hit him, and even if he could, it wouldn't kill him, because hybrids can only be killed by being beheaded or having their heart ripped out. Jeremy then shot an arrow at Tyler, but he deftly caught it in mid-air before it could hit him.
Jeremy later invited Tyler over to the Gilbert House for lunch, though both Elena and Alaric argued that inviting Tyler in wasn't a good idea, since they knew that he was sire-bound to Klaus. Jeremy, annoyed by Elena and Alaric's bossiness, stubbornly stood his ground by inviting Tyler into the house. Elena and Alaric tried to take advantage of their situation to see how the sire-bond worked by asking Tyler questions about the difference between compulsion and a Sire Bond. Tyler explained to Jeremy, Elena and Alaric that compulsion was something you were forced to do regardless of whether you wanted to or not, but that a sire-bond was like having faith, and that Tyler owed Klaus for turning him into a hybrid so he didn't have to transform every full moon. Elena and Alaric became uncomfortable about Tyler's dedication to Klaus, and Tyler eventually left to avoid their questioning. While Elena and Alaric talked privately, Jeremy received a cryptic phone call and left without telling anyone, and it quickly became clear that he had been compelled, because he had taken off his Gilbert ring and unconsciously stood in the middle of the street as Klaus' hybrid Tony sped toward him. It was later revealed that Tyler had been instructed by Klaus to get Jeremy off of vervain so he could be compelled as a way of manipulating Elena into getting Stefan to give back the coffins containing Klaus' siblings and mother. Later, Jeremy confronted Tyler in the woods with Alaric's cross-bow and tried to shoot him with it. When Tyler yelled at him for it, Jeremy pointed out that Tyler was the one who had gotten him off of vervain, which almost got him killed, and Jeremy reminded him that whenever Klaus tries to get what he wants, other people end up getting killed.
In We All Go a Little Mad Sometimes, Jeremy arrived at the Lockwood Mansion, which surprised Tyler. When Tyler confusedly asked, "Jeremy?" one of Tyler's hybrid friends, Chris, stood up, and Tyler was forced to watch as Jeremy, who had just learned he was a potential hunter of the Brotherhood of the Five, killed Chris in order to save his sister from the Hunter's Curse after she had killed Connor Jordan, another hunter of the Five.
In Rescue Me, Tyler saw Jeremy having an intense conversation with Liv, a witch friend of Bonnie's, but when he tried to eavesdrop, he was surprised to find that he couldn't hear anything they were saying with his hybrid hearing. When Tyler saw Liv leaving, he noticed that Jeremy had shouted after her, so he stopped her and told her that it was rude for a "newbie witch" to leave Jeremy hanging. Liv simply told Tyler that she wasn't a newbie witch and used her magic to telekinetically throw him across the room so she could leave. Later on, Matt and Tyler confronted Liv's twin brother Luke to question him on what he and his sister were planning with Elena and Stefan. Jeremy ultimately made a deal with Liv to protect Elena and Stefan in exchange for his help, but insisted that they had to allow Tyler and Matt had to be allowed to help as part of the deal, to which the twins reluctantly agreed.
That night, Jeremy informed Elena and Damon that he was moving out of the boarding house and living at the Lockwood Mansion with Tyler and Matt.
