Claus is finally dead...well, his physical body died and gets resurrected in the body of Tyler. Apparently, there's going to be a twist in the list of antagonist in the next season. But that's just me. Good thing is Caroline will no longer be tangled in terms of his feelings for Claus. Admit it girl! You've got a thing for the guy!
Elena finally chooses between the Salvatore brothers only to get killed in the end. Yeah...she dies in the finale and the vampire nation celebrated the concurrent demise of Alaric who was created by the Original Matriarch to annihilate all vampires. Oh but don't worry, in the final sequence Elena makes an Eclipse-like revival. Can't have a fourth season without Elena there can we? At least she won't be the weakling she used to be in the last three seasons.
Season 4 will air in October 2012.
