It's official: the worst thing has happened. Aunt Jenna, sweet, innocent Aunt Jenna, has been killed. Technically. She's in transition and it remains to be seen what choice she makes. And it's all so Klaus can break the curse that was put on him and him alone: that's right, kids, The Sun and the Moon Curse is just a big lie that Klaus has been telling for a thousand years as a way to make sure that werewolves were looking for the moonstone and vampires were on the lookout for the Doppelganger. And because of this, it looks like we're going to lose Jenna.

Oh. And as a way to keep Elena from dying, Damon forces her to drink his blood, so she has to make the vampire choice too. Great.
