Echo guesses that Clyde's friend betrayed him, and Clyde affirms that, saying he trusted him or her, but he or she was the one that gave Clyde 2.0 the order to double-cross him, and that was the beginning of the Attic -- they cleared his head out and made him a human computer, which happened back in 1993. His nightmare, or "loop," has been to run statistical scenarios to see where the technology might lead, and in all but three percent, civilization ends. But are we talking Lord Of The Flies, or something more Biblical? I just want to be clear on my options here. Clyde asks what year it is, and when Echo guesses 2010 ("I don't know how long we've been off the air," and at least they have a sense of humor about it), Clyde perks up, as the future he's envisioned hasn't yet come to pass. He tells them the first thing Rossum will do is install an imprinted person in the government, and when Echo's like, they did that already, Laurence and Clyde amusingly reply in unison, "They did?" Clyde says that puts them ahead of schedule, and then Laurence asks who Clyde's old partner is, but he's unable to remember faces or names from the outside, "not to mention the fact that Clyde 2.0 has probably switched bodies by now!" Hmm, Topher and Bennett seem like the only candidates smart enough, but we've seen hard evidence that neither of them is a Doll. Maybe his personality is in Alpha at the moment? That could be interesting. Oh, wait -- what about Whiskey? That could be it, no? On top of that, I should add that we don't know that everything Clyde is saying is true -- he could be using this group to try to advance a private end, possibly placing revenge on his partner over the greater good. But anyway, Clyde goes on that if they could eliminate "that backstabber and the copy of me that does his or her bidding," they might be able to stop them. Priya points out the big and immediate problem, though, that being that there's no way out of the Attic, and Clyde confirms that's true. Victor adds that they have no way of identifying the traitorous element, but Clyde says there's been talk amongst the security personnel that a woman was mistakenly allowed to see them, but they scrubbed her clean -- and with a flash of realization, Echo breathes, "Caroline." FINALLY, an actual reason for Caroline's importance! Didn't think the show could or would give us that, but here we are. Clyde confirms that "Caroline" rings a very large bell, and Echo reveals that that was she, but she doesn't have access to any of her memories at the moment. Just then, someone fires through the wooden slats shielding them from the outside, and after they all take cover, Laurence asks what would happen if their bodies were disconnected from the Attic by someone on the outside. Clyde says brain death would be the result, so Echo tries the effect of a desperation move -- taking a bullet in the gut. After she sinks to her knees, she breathes, "I know a way out," which is all well and good, but if she tells them that death is her gift that's going to be a meta reference too far.
