So yeah, Stefan figures out that killing an Original kills his vampire descendants. Caroline realizes the personal implications. Elena voices them: "If the Originals die. So will all of you. The vampire species would be dead." Silly Elena, you say that like it's a bad thing. Sorry, apparently I'm channeling a little Xander Harris, today. I don't really want "our" vampires to die (much).

Back at Klaus Haus, Damon is hanging out (sorry, again). When Stefan comes in to rescue him, Damon says, "This was much different in my head." Poor noodle. Stefan hollers out for Klaus, who enters the room with Rebekah on his tail. Stefan throws down his bag full of Son of White Oak stakes. He'll trade them for Damon. Rebekah doesn't believe the stakes are certified Son of White Oak, but then Stefan tells them about killing Finn. Rebekah reacts to this news. Klaus remains silent, so Stefan presents his deal again. He wants Damon in exchange for the eight remaining Son of White Oak stakes. Klaus wonders how he'll know there aren't any more left, and even though I know the Fellowship made twelve stakes, I totally believe Stefan when he says there aren't. Klaus is smarter than I am, though. He goes over to Damon to see if he's compellable yet. Damon struggles against the compulsion at first, but then Klaus orders him to go home. Poor Damon starts trying to pull his hands free. The trap teeth rip through them. Stefan can scarcely stand to watch. Rebekah, who has been torturing Damon for hours, is also affected. As Damon screams, we cut back to...

Mossy Manse. Caroline returns complaining about vampire disposal. Elena tells her Stefan is off trading the stakes for Damon, but they still have enough to kill three of the remaining four Originals. They just have to figure out who to save. Damon turned Caroline and Abby. Katherine turned Stefan and Damon. Rose turned Katherine. They have to figure out who turned Rose. Elena just hopes it wasn't Klaus, so that they can still kill him. It's then that Caroline points out that Klaus turned Tyler. If they kill Klaus, Tyler will die.
