Dylan O'Brien has become a fan favourite playing the impish Stiles.
Fiercely loyal to his best friend Scott, and hopelessly infatuated with mean girl Lydia (Holland Roden), Stiles always seems to end up finding the humour in any dangerous situation.
This is the 20-year-old O'Brien's first major role.
For someone who started off making videos on YouTube, the New Yorker of Irish, Italian, Spanish and English heritage is certainly going places fast.
How do you feel about being asidekick?
I don't think anybody's a sidekick on the show. It's an ensemble cast. What the show really focuses on is the story of these six main characters.
I'm totally fine with Stiles being labelled as a sidekick, but my job as an actor is to not think that way.
I have to look at him as more prominent than that or else the character will kind of fall flat. I've got to give him some depth.
Why doesn't Stiles want to be a werewolf? And with his crush Lydia transforming this season, would he change his mind just to keep up with her?
That's a really good question.
Stiles doesn't take the bite in the first season because that's the essence of Stiles.
He's loyal to Scott. He knows that he's got to be human and he's got to help his friend.
As for Lydia, I haven't really thought of that. If Lydia became something else, would Stiles change his mind? I think that could very well be the case.
In season 3 or 4, when everyone else is a creature, maybe Stiles will want in too. (laughs)
What challenges does Stiles face in the second season?
I think the challenge for Stiles would be to decide whether he's safe in all this. It's the first time we're going to see Stiles contemplate whether he should be involved in all this or not.
I think his instinct is to help out and protect his friends, but he might get to the point where he realises he's very human, and vulnerable.
As things get crazier around him, he might have to consider pulling out.
