'The Vampire Diaries' at Comic-Con: Cast on Elena as a vampire and 'True Blood' rivalry

There will be some big changes in Mystic Falls when The Vampire Diariesreturns, since Elena was changed at the end of last season.

During an interview with EW’s Tim Stack at Comic-Con, Nina Dobrev explained that “we don’t know” what kind of vampire Elena will be.

But Ian Somherhalder ventured a guess. “Damon and Stefan have been known to be extremely volatile,” he said. “By virtue of the fact that Elena is such a solid human being, even though she’s sort of this beacon of light, and shepherd through the valley of darkness for other people — who’s to say that she’s going to be this way when she becomes a vampire.”

Plus how do they feel about that other vampire show — True Blood? Watch the full Comic-Con chat below to find out.  VIEW THE VIDEO AT EW.COM >>
