Sam and Echo arrive at his room, and while she tells him she went to Colby, he changes his shirt, which is the kind of gratuitousness I can get behind. After Echo babbles for a while about her state of mind, Sam gets out a map of the campus, and after a little talk about how Sam's mother is the primary influence in his life, Echo says that "underneath" is the way in, and adds, "Lily Foundry. We have to find Lily Foundry." Sam's like, "Effing terrific."
Topher's hair is getting out of control as he slowly tells Victor via the telephone that he has to get any Rossum operatives off the Fremont grounds and send them back to the Dollhouse, as while he and Sierra and his team of Dolls will be fine, everyone else won't. Meanwhile, Adelle is yelling to him to say hi for her as she's bouncing up and down outside the glass like she's on a mini-trampoline, although we'll learn later it's a couch, and as funny as everyone is, I have to give it up to Olivia Williams in this episode, because the woman seriously commits to the idea here. Topher manages to convey his message despite the effects of the drug, and another point I like here is that he's more coherent than the others, because if you have experience with psychedelics you can control their mental effects to a surprising degree, and it was pretty heavily implied that he's, er, unlocked his brain at times in the past. However, as Adelle most unglamorously climbs back over the railing into the lab, we see that whatever control Topher has did not prevent him from removing his pants and standing before us in boxer briefs. After some more hilarity that includes Adelle's hair suddenly and completely going on strike, she mentions that she has a story about Victor, which could be more than just a throwaway moment, but Boyd then calls, and Adelle grabs the phone and asks if he found Echo. He tells her he's "worked it out," and when she asks what he means, he sits down to a piano in the frat house (...okay) and starts playing rather beautifully. Adelle, moved, puts the music on speaker, and she and Topher practically melt into each other as they listen in delight. Adelle, he's already in his underwear, and you could do worse. You could do better, too, but better isn't ready to go at the moment.
While looking for Lily Foundry, Echo runs into a woman who addresses her as "Caroline Farrell." The woman just so happens to have been a history professor of Caroline's, but unfortunately, the drug has affected her, so Sam doesn't pay her any mind. Echo, however, looks uncertain, and between this and her run-in with Ballard last time, I wonder if her real name will stick with her this time.
