Vampire Diaries' Trevino Looks Back on Tyler's Progress, What Could've Been Forwood's Future

When Michael Trevino laughed after we asked him if Tyler and Klaus would have more scenes together in The Vampire Diariesseason finale, we never could've predicted why.

"Um, maybe they have a little run-in," Trevino, who plays Tyler, teased to TVGuide.com.

Understatement of the year. On Thursday's Season 3 ender, Klaus (Joseph Morgan) took over Tyler's body (and that was just one of the episode's shocking developments). Caroline (Candice Accola) was in hysterics as she watched Tyler — with whom she had just agreed to run away — scream in pain. But while Caroline believed Tyler was dying as a result of Klaus' death and their sire bond, Klaus was actually transitioning into Tyler's body in order to survive.

Although Trevino's role is about to change drastically, the actor says he's incredibly proud of the way Tyler Lockwood grew in the first three seasons.

"I was really nonexistent in Season 1. Tyler was really one-note, a jerk, and an alpha male d-----bag — it was boring and I was frustrated," he says. "To see how fast Tyler's arc has progressed from Seasons 2 and 3 — when he first found out about the werewolf thing, then he turns into a werewolf, and in Season 3 he becomes the first successful hybrid, and his relationship on and off with Caroline — I like the way things went and that he grew up."

But what is one plotline Trevino wishes Tyler could've seen through? His relationship with Caroline, of course. "I would've liked to [have seen] how the relationship with Caroline would blossom without the distraction of other people, if nobody was getting in the way, and how deep their relationship could get and if it would last."
