'The Vampire Diaries': Matt's meltdown continues in 'Know Thy Enemy'

tvd-enemy-vid.jpgThe most recent episode of "The Vampire Diaries" ended with a series of cliffhangers... just what we like to see before a six-week hiatus. We were surprised to see that Caroline ( Candice Accola) finally came clean to Matt ( Zach Roerig) about vampires.

He didn't take it quite as well as she'd hoped. Putting two and two together, he realized that his sister Vicki was likely killed by a vampire, and he totally lost it. He still doesn't know that when she died, she was a vampire.

In the next episode, airing Thursday, April 7, we'll get to see the fall-out of the revelation -- and it looks like Caroline isn't going to compel Matt to forget the bad news, or even to calm down about it. We're pretty thrilled by this revelation, because Matt has been compelled enough. It's time to see some aftermath. If Matt tells Sheriff Forbes (Marguerite MacIntyre) that her daughter is a vampire, will she need to have her mind erased again?

Watch the new preview clip below. This looks to be an action-packed episode -- now that Isobel's back, tensions are rising not only with Elena, but with the adult characters on the show.
