Among the many Vampire Diaries spoilers that producer Jule Plec recently shared was this nugget concerning Caroline and Tyler:

"They’re gonna go through hell and back with each other."

What, exactly, does that mean? How will the relationship between these two progress? Zap2It asked those types of questions to stars Candice Accola and Michael Trevino. Excerpts from their answers are below.

Accola, on where Caroline and Tyler stand: I think it's a beautiful parallel for both of these characters that are kind of embarking on this new part of their lives in such an extreme supernatural way.

Trevino, on what his character is thinking these days: Why does she stick around? Why is she caring for Tyler, this douchebag jock?

But what about Matt? Says Trevino: Now we have this triangle. Tyler and what he's going through, and what he's going to go through, and Caroline and Matt. So for a few episodes I think there's going to be  this trio, this dynamic of questioning and wondering... You're going to see Matt investigate some things.

Accola, on Matt/Caroline: There are certain experiences that happen in someone's life that bring people together that wouldn't normally really have anything in common. And as much as you can try to relate, and try to relate, sometimes you just can't. I think that's going to be a big obstacle in the Caroline/Matt relationship.

The Vampire Diaries returns with a new episode on December 2. Watch the official preview for "The Sacrifice" NOW.
