Charm School. Michael updates Percy on what we just saw and then together they go in to visit Birkhoff in the medical lab. He passed the lie detector test, but an X-ray shows there's a small transmitter implanted in one of his molars. Since his face had already been beaten all to hell at the time, he didn't notice a little extra dental pain. Percy orders the tooth removed. Birkhoff poops himself a little.
North Virginia State campus. The source hasn't showed up, probably because he saw Jill on the news and got scared. Nikita thinks for a second and decides they need to track him down themselves.
Charm School. Thom, Jaden and Alex are going over a pile of information for their "training exercise." Alex notices there's a lot there about a plane crash. "Maybe she caused it," Alex says. Thom wonders how Alex knew it was a woman. Alex holds up a journal still whiffing of grapefruit and vanilla candles. They figure out from some notes that there was video of something in Virginia on the Appalachian Trail. Thom is impressed.
Campus. Nikita works her mental mojo and exposits a bunch of stuff, the upshot of which is that the mystery source is an ambitious hiker and college student. They decide to hit the sporting goods stores in the area.
Charm School. Jaden calls over Michael. "Alex here seems to have it all figured out," she says, clearly hoping Alex will crash and burn. But Alex details their findings, including two movie ticket stubs in Blacksburg, Virginia. Alex is sure that's where the terrorist and munitions expert met, since driving all that way to see an Elmo movie is "way weird." Michael leads Alex to the ops room, where she tells Birkhoff about her findings. Michael tells him to check the movie theater for night vision cameras. That's... convenient. At this point, Alex realizes the work she just did was for an active mission and not just a training exercise. Oops. The source, one doomed Benjamin Prentiss, even used his credit card to buy popcorn. Michael allows Alex to stay in the ops room as a reward. Birkhoff brags about his network some more and doesn't notice when Alex moves his can of Red Bull closer to his hand.
