Tyler gets Caroline alone in an upstairs bedroom and asks what she's up to with Klaus. And this must be exactly why the Fellowship of the Falls didn't include Vampire Barbie in their plans. Normally, I'd say that was stupid, but the secrecy -- it works this week. When Tyler accuses Caroline of lying, she laughs. "You know actually, I'm not. I don't know anything. But if I did, I wouldn't tell you anything, because you're sired to Team Klaus, now, and you can't be trusted, so can we please just go back to the party." Tyler nods, but then he sticks a hypo in Caroline's neck, shoots her full of vervain, and lays her on the floor, even though there's a bed right next to them. Gimme a newspaper, so I can swat him on the nose!

Outside: Klaus talks to Elena who is antsy and jumpy. She tells him MtVVS came at her, so she had no choice but to dagger him. Klaus is impressed she could dagger an Original. Elena says it wasn't her first time. Klaus laughs. "Right, Elijah." He then huffs and puffs about how he's been a target for 1,000 years, so she and the Fellowship of the Falls can take their best shot at him, but they won't succeed.

Front Entrance: Some Werepire Muscle tries to stop Damon at the door. "Invite only, vampire." Damon says, "Here's my RSVP..." he plunges his hand in the werepire's chest, rips out his heart, throws it to the ground, then adds, "Hybrid." Heh.

Bedroom: Matt takes Caroline's pulse (would she have one) and asks Ty what he did to her. Tyler explains her shot her full of vervain to keep her far from the attack against his master, because the place is crawling with sire-bonded hybrids hellbent on protecting Satan Klaus. Matt is disgusted that Tyler could attack Caroline. Tyler says, "I'm protecting her, Matt. This is the only way to keep her safe. Please, just get her out of here, safely. Get everyone out."

As soon as Tyler gets downstairs, Damon grabs him and shoves him into the study. Once they're alone, he tells Tyler the loads of hybrids do not make a good impression. Tyler warns that his sire will be ready for any move they make. The two struggle. When Damon goes to snap Tyler's neck, to take him out of commission for a bit, Tyler goes to bite Damon, which would take Damon out of commission forever, so Damon pulls out a stake -- wait, not just A STAKE -- the magical white oak stake and goes to plunge it in Tyler's chest. Now, that's an Original killing weapon, but it works on hybrids too? Ugh. I feel like I have to watch all of last season again, to get my mythology straight. It doesn't matter, because Bonnie comes in and magically diffuses the situation, knocking out Tyler and giving Damon a mystical migraine. When Damon gives her flak for it, Bonnie reminds him he wasn't supposed to kill Tyler. Damon explains Ty tried to bite him, but Bonnie changes the subject when she spots the very special stake Damon is stashing in his jacket. He shushes her when she tries to ask if it's the magical white oak stake, because Klaus's minions are everywhere. When asks why he has it, Damon says, "Because I'm the only one who can get inside the house."
