Up in Elena's room, the girls sit around a bunch of candles on the floor, and Caroline leads, because Bonnie wants no part of this. When Caroline brow beats her into calling on Emily, she does so -- with as little feeling as possible. But then, all hell breaks loose. First, the candles flare. And when Caroline requests a sign from Emily (because Bonnie won't) the windows fly open and Bonnie freaks. She throws her necklace down by the candles as she screams that she can't and won't. The wind (or the spirits) blow out the candles and when Elena hits the lights, the necklace is gone. Commercial!
MFHS Football Field; Night: Stefan and Damon toss around a football and get to the heart of things. He tells Damon that once he came to terms with the fact that Katherine compelled them to love her, he was better able to get over her. Damon doesn't want to go there. Stefan then asks what Damon wants with Katherine's crystal. He knows about it, because he was the last one to see Katherine "alive" which really upsets Damon. He wonders why Katherine didn't tell Stefan why the crystal was important. Stefan sneers. "We had other things on our mind." Damon gets in his face (with vamp speed) and says he could rip out his heart without thinking twice. Stefan joins us all in saying yeah yeah, tell us another one. Damon says he has a bigger surprise. He's going to bring Katherine back.
Gilbert Gables: Elena sees something (someone -- it's Emily) in the hall and goes to see if it's Jeremy. It's then that Bonnie spots the crystal on the bathroom floor. When she goes in to retrieve it, the door slams shut. She can't get out and the girls can't get in. The lights flash on and off and I bet they're wishing Sam and Dean would come to their rescue right about now. When the excitement subsides, Bonnie stops screaming and opens the door. She covers her face with her hands for a moment, and when she finally takes them down and monotones that she's fine, it's clear that Bonnie's not home anymore. Well, it's clear to everyone who isn't Caroline. She's sure Bonnie is just playing them and is ready to stomp off. Elena knows things aren't right, though. And so do we, because when we get a look at the bathroom mirror, it's not Bonnie's reflection we see there. It's Emily's.
MFHS; Exterior: Damon brings Stefan's mind back to the general mood of Mystic Falls before Katherine and "the others" were killed in the church. There was a lot of hysteria (on account of the town being overrun with vampires, so I'd say that's not so much hysteria as SENSE). Anyhow, Damon made a deal with Emily. Since the locals were bound to go after the witch, once the got the vamps, he'd keep her progeny safe if she'd protect Katherine with a spell. Katherine didn't burn up in the church. She's magically sealed beneath it -- like the Master -- thanks to the crystal, and Emily's ability to call on the power of the comet. In order to get the crystal to work again, the comet had to return, which it just did in the second episode, so yay! I mean... woe.
