In Security HQ, Washington waves Jim over to watch Skye sneaking out of Terra Nova, which hits Jim so hard that he closes his eyes and lowers his head. How did she not crack under his rigorous interrogation? She wants to notify Taylor, and he tells her that he wants to "double-check something" first, but he doesn't say what. If I'm Washington, I think I'd say, "Yeaaaahhhh, I'm just going to go ahead and tell Taylor."
Jim goes home to ask Josh, currently Jack Johnsoning out on his plywood guitar, "You weren't with Skye last Thursday, were you." Well, it's not a question as much as a statement of fact. Josh hangs his head and admits he wasn't, but says she asked him to say he was. But he doesn't know why it matters: "I thought you were looking for a Sixer spy," he says. Yeah, see, Josh, this is why your chess-at-dawn lie wasn't the greatest idea. "Josh, you're my son, and I love you very much. But don't lie to me again," says Jim, like up until now Josh has been Mr. Teenage Honesty. Then Jim takes the plywood guitar and grounds Josh, which is both a punishment for him and a reward for everyone else. Elisabeth, who is barely in this episode despite being the most beautiful thing on screen apart from dinosaurs eating people (which also doesn't happen this episode) asks what's going on and Jim says he found the Sixer mole, and Josh has been helping her cover her tracks. Well, when he puts it that way, I think grounding plus guitar confiscation is actually a little lenient.
Taylor looks gutted by the news, but Jim says he's been going over her whereabouts and is sure. "I got a man inside the Sixer camp," says Taylor. It's Curran. Taylor says he'll get a message to see if Curran can confirm it's her. Jim seems surprised by the news of Curran's embedding with the Sixers. "After I banished him, I thought I'd make us of him, give him a chance to earn his way back to the community," explains Taylor. Uh, did it occur to Taylor, if he can communicate with Curran, to ask, "So, who from the colony keeps dropping in to provide intel?" Anyway, Jim wants to go round Skye up, but Taylor says he has a better idea.
