In anticipation of tomorrow’s The Vampire Diaries premiere, the cast have all been busy doing interviews teasing what’s coming up in season 4!

We’ve got video interviews with Ian Somerhalder (Damon), Zach Roerig (Matt) and Candice Accola (Caroline) all previewing what their characters will be up to when The Vampire Diaries returns for its fourth season tomorrow night.

First up, Ian Somerhalder chats to Zap2It about Damon, Elena, and his hopes for season 4.

After Elena’s blatant rejection of Damon in favour of Stefan in the season 3 finale, Somerhalder reveals that Damon will, “Definitely be pining significantly less. And by pining I mean like ‘Aw, she doesn’t love me,’ that kind of thing.” In the fourth season, “there’s a whole other element that is sort of in play here,” Somerhalder explains, and now that Elena is becoming a vampire, “it’s altering the course of the way things are going down in Mystic Falls, at least between Stefan, Elena, and Damon.”

He also addresses Elena’s bloodlust, and likens it to that of a kitten wanting to play. He says, “You’re supposed to play with it, give [it] toys. You’ve got to allow it to advance its skills as a hunter, as an individual. Effectively the way Damon sees Elena being led into this, it doesn’t make any sense. There’s a huge downfall that he sees, which is that if she does not experience first hand this bloodlust, there’s no way in hell she’s going to be able to control it. She’s not going to know what she’s up against.”

Somerhalder has also spoken to TV Guide, about Damon’s role in Elena completing her transition:

In the video, Somerhalder reveals that, “Damon is the key to her understanding a lot of what’s going on during the transition. He even [tells Stefan], ‘She’s not going to be able to understand this blood lust, so let her feel the urge and the pain and hunger. That way, she knows what she’s up against.'”

Next, Zach Roerig talks to MTV about Matt’s role in season 4, and the guilt he’s been feeling about, to some extent, being responsible for Elena’s death. The actor reveals that Elena will indeed be drinking Matt’s blood, and that both Stefan and Damon will be blaming Matt for what happened, believing that he “needs to earn his survival.” Damon, “doesn’t think that Matt deserves to live. But thankfully Elena is there to defend him.”

Matt and Elena will be growing closer this year, Roerig says. “The fact that Elena gave up her life for Matt; and then Matt allowing Elena to feed from him: it’s just a like a sacrifice on both ends on an extreme level that brings them really close together.”

He also makes a case for Matt staying human, on a show where it seems everyone has a supernatural ability. “I think it would be a big mistake to make Matt supernatural, for his character and for the show, honestly,” Roerig says. “There needs to be someone who has no facets of the supernatural world, whether it be a ring, a curse, what have you. It’s a grounding element for the show.”

Finally, Roerig teases the arrival of Grace Phipps’ April, saying, “As far as April goes, everyone is kind of surprised to see her. Jeremy and Matt run into April at the same time. Neither one of them recognize her because she was this little girl to them that Elena used to babysit who has now arrived back at school kind of grown up.”

Here, Candice Accola talks to TV Guide about Caroline’s conflict in this season:

Accola talks about Klaus occupying Tyler’s body, saying, “She does figure out Klaus has played the switcheroo gag on her and she’s not happy. But the bright side is Tyler’s not gone… Her love isn’t gone.”

But there might be trouble brewing between the pair, partly due to the arrival of Phoebe Tonkin’s Hayley. “They have to face up to reality [and] it’s not going to be easy and it’s not going to be pretty,” she says.

We can’t wait for tomorrow night, when The Vampire Diaries returns at 8/7c on The CW with “Growing Pains”!
