Lockwood Mansion: When Tyler says his mother would freak if she saw the crowd at their place, Klaus says, "Your mother won't be a problem. I compelled her to go to church and pray for your friends." When Tyler doesn't get what he means, Klaus points out the locations of Bonnie, Elena and Matt, and "...your pretty little girlfriend, Caroline." He then mentions how many people are at the party who Tyler doesn't know. It seems Klaus has invited a few dozen friends of his own -- hybrids. How much blood did he get from Elena, anyhow? Klaus reminds Tyler that like him, the other hybrids are loyal to and wish to serve Klaus. "So if anyone should so much as make a move against me, they may feel obligated to retaliate." Klaus takes a beat and then smiles. "Feel free to warn your friends." Commercial.
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."
