9 Things the Vampire Diaries Season Finale Killed

Good riddance. Though Kai had actually become pretty entertaining, there was no way he could be allowed to live after the unspeakable things he does on Alaric and Jo's wedding day. It seems like he's going to be truly immortal after he kills himself, becomes a vampire, and then gets bitten by Tyler as a werewolf. He can heal that, but he can't heal his head being knocked off. It's nice to know there are some failsafes in this world.
