The Vampire Diaries Episode 21 trailer begins with the vampire crew in a panic over Bonnie’s new outlook on life. Enzo declares that Bonnie waking up means she’ll have to kill them all, seeing as she’s a deadly vampire hunter now. Once Bonnie is awake, Damon taunts her by teasing “catch me if you can.” Bonnie has never been one to be toyed with, but now that she’s a witch AND vampire-hunter, and let’s not forget her fiery temper, she’s more dangerous than ever. Stefan says to Caroline:“You’re the first person she kills.” Yay at the fact that they’re actually talking to each other, although it sounds like he’s saying this to dissuade Caroline from trying to help Bonnie. We all know that Caroline will do anything, even get herself killed, to help a friend. It doesn’t take Bonnie very long to get into hunting mode as we see her stab Caroline with a shard of wood, and break someone’s (we think it might be Enzo) neck. Bonnie throws a metal spike at Damon, and then has him pinned downed as she pushes the spike into his chest while Damon begs Bonnie to forgive him. Do you think the vampires will find a way to stop Bonnie before she kills them all?
