FIVE YEARS EARLIER, in BOSTON, MA. Sean swims in what I think is an Olympic-sized swimming pool. He sees Leila flailing around in the next lane trying to learn to backstroke. They have awkward, unconvincing small talk. She admits that she doesn't know how to swim, and there's no chemistry at all here. It's almost hard to watch. He denies being captain of the swim team, but cops to being in the computer science society. Then he gives her some technical posture suggestions about where her chin should be when she's floating on her back. I hope this comes up in a future episode, because this had better not be here just because they wanted to explain how Sean was able to save Leila in the last episode. He leans her back. They're playing up the awkwardness so much that I can't imagine either of them wanting to speak to the other again, but he suggests meeting tomorrow for another lesson. That's the end of the flashback, and I'm beginning to think it would be a good idea for these flashbacks to tie in to the main storyline in some way. As it is, it's like they didn't want to bother connecting their scenes in any way other than the occasional "THIS HAPPENED EARLIER" caption. It does not, in my opinion, lead to a compelling narrative.

Meanwhile, Sean runs down the hospital hallways, knocking people over. He ducks into a room with no lights on. The cops run past, and he pops back out to run the other way. More running. He turns left a lot and ends up in front of the cops again. That's when he falls down. Good one, dummy. He's arrested for the murder of Greg "Dude" Kervin.

Back to the airport! Sterling tells Agent Simon Lee that Sophia has been lying to them all along. I'd like to hear some of these lies she tells. I bet it would be interesting. Anyway, Sterling is putting together a hand-picked squad of Top Men to find the non-detained Detainees and determine the full extent of their capabilities. He cautions Simon that there's no way to know how far they've been infiltrated. The camera holds on Simon for a suspiciously long time, and then it's time for a flashback.

TEN YEARS EARLIER in LANGLEY, VIRGINIA, a nurse (not the same one as in Yuma) has trouble taking blood from Simon's arm. He explains that his whole family has "small veins" and they chat about how he's just become an official member of the CIA. He applied for Clandestine Services, although based on his performance in the last episode, he's one of the least clandestine people I've ever seen. Then he strolls into the bathroom, looks around suspiciously, and ducks into a stall. He pulls a piece of tape off his bicep and pulls a length of fake vein out of his arm. That's gross. And indiscreet. Shouldn't you wait until you're home, rather than just doing this in the CIA bathroom?
