Damon finds Elena sorting masks. He's looking for Stefan and he's also hoping Elena will tell the Germ to stop following him around. As Damon ambles off, Jeremy wanders up. She warns him off of the Evil Pixie Monster, but this week, Jeremy thinks he's John Locke, so he's all don't tell me what I can't do. Thank goodness his hair looks good.
Outside, Stefan catches Damon up on the Katherine/Brick House situation. Damon is offended. The dude's a surfer, dude. Damon shares the moonstone intel and tries to figure out what's going on. The boys argue about Jeremy being involved and Stefan stalks off.
Across the lawn, Matt catches Ty up on his break-up with Caroline. In short, she's awesome one moment and a jealous freak, the next. Tyler says, "You know what I think of Caroline Forbes. She's an insecure, neurotic, bitchy little twit." Matt, to his credit, says, "Hey!" but Tyler continues. "But the girl's got heart. She means well. You've just gotta take the good with the bad, sometimes." You mean like how your uncle is in bed with the Queen of the Damned, but I love him anyhow? Huh. Good point, Ty. Matt agrees so much that he's inspired to get an extension cord. Hey, don't look at me. That leaves Tyler alone, so Jeremy approaches, hoping to get the moonstone off of him. Damon and Stefan overhear when Tyler explains that he's done with legends and curses and has handed the moonstone over to Uncle Brick House.
There's a whole lot of texting between Elena and Stefan, mostly initiated by Elena when she doesn't know what's going on. If I cover it, I'm going to put us all asleep, so assume that every 15 seconds, she's texting Stefan, all WTF? Are you OK? WTF? Stefan and Damon pull Bonnie aside. They need her help to figure out what's going on with Katherine, and to get the moonstone from Uncle Brick House. She is not at all interested, which leads me to believe she's never gotten a good, long, hard look at Uncle Brick House, but perhaps I'm being transfer-y. When Elena gets no answer from Stefan, she forsakes texting and calls him. Stefan warns Damon to be nice to Bonnie as he walks off to take the call and catch Elena up on what's going on. Damon is anything but nice as he demands Bonnie's help. She explains that when she gives Damon the mystical migraine, it's really her giving him an aneurism, but because he's a supernatural critter he heals almost immediately, so she gives it to him again, and again and again. I knew I liked this girl for a reason. Damon wonders if it would work on other critters. Bonnie says sure, provided they're supernatural critters. When Damon starts coming down on Bonnie too hard, Stefan returns and smoothes out the lumps we like to call Damon. The bottom line is, Bonnie, they need your help, because your alleged best friend's doppelganger is about to open a can of whoop-ass unlike anything Mystic Falls has seen since the Civil War. You dig?
