Elena finds Bonnie out on the Lockwood lawn, but the tension between them is still carving-knife thick. When Elena tries to convince Bonnie to stay in touch with Caroline, Bonnie bites back at her, and lays on the guilt about how she's lost not only Care Bear, but Elena, too. Elena pulls her away, so they can have a private chat.
Mossy Manse; Detox Dungeon: Caroline tells Liz that the vervain is almost out of her system and she should be compelled and returned to her normal life as soon as tonight. When Liz is predictably cold to her undead daughter, Caroline bitches about how she died and all. This catches Liz's attention and love. "Are you -- are you really dead?" Caroline: "Yes and no." Liz: "How is it possible?" Caroline: What are you, Oprah? Fine, I'll explain, but I'm not jumping on your couch.
Upstairs: Damon welcomes Alaric. They're still trying to make "Ric" happen. I'm still ignoring them. You're on my side, right? Alaric has brought over Isobel's research. He's surprised to see Jeremy in Damon's parlor, but doesn't let that delay him from getting down to business. He reminds Damon of the Aztec curse on vampires and werewolves, and says that a moonstone is used to seal the werewolf part of the curse. Damon's not anxious to buy into a bunch of woo, but on the other hand, he's a vampire who is vulnerable to the lycanthrope's bite, so he can't ignore it. Plus? Damon's always up for a haphazardly planned caper.
Lockwood Lawn: Bonnie feels left out of Elena's life. Elena tries to reassure here that she's as important as her fangy friends, but when Elena brings up Caroline, Bonnie turns to stone.
Across the lawn, Stefan and Mason greet one another but keep the fangs and tail on the down-low. When Mason asks after Liz, Stefan assures him she's fine, but that from now on, he'll have to do his own dirty work. Mason says that's not a problem and turns to go, bumping into Bonnie and giving her a powerful vibe. Once Brick House is gone, Bonnie confesses to Stefan the subject of her vision. It was Elena -- macking on Mason. Stefan starts to object and then realizes the truth: Bonnie didn't see Mason and Elena; she saw Mason and Katherine. Commercial.
