So he heads outside to his new job, and he's accosted by Skye, who faux-casually requests that if Jim asks where he was at the aforementioned time, just say he was with her. He's intrigued by this, and asks what she was really doing, and she finally comes up with a lie that involves stealing copper tubing for a new still.
Anyway, having gotten the information out of her, he suddenly gets all pious about how she's asking him to lie to his dad, as though it's not something Josh does all day long, but she eventually wheedles a promise out of him.
That night, she sneaks out through the gate -- good thing security is so much more vigilant these days! -- and heads to some sort of, I don't know, communications outpost? Where she grabs a sonic weapon hidden above a grate.
Then it's off to the Sixers' camp to see her mom -- after she provides the necessary intel -- and she meets Lucas, who has a job for her. She refuses, initially, saying she works just for Mira, but Lucas impresses upon her that Mira works for him. Plus he threatens to throw her mom off the treetop camp if she doesn't bring his two-way portal formula back to Terra Nova so she can factor and reconcile the equation in the Eye, which will be a lot quicker than if he has to do it by hand. Not really wanting to her mom go splat on the forest floor, Skye's going to do it.
Back at Terra Nova, Washington's reporting to Jim (which I'm sure she must love) that she found a drainage ditch on her perimeter patrol that could be an exit through the gates. Jim tells her to put a security camera on it and double up on the west perimeter patrol.
And there goes Josh, offering his father a "Hi, Dad" as he heads of on his way to some sort of shenanigans. Jim seizes the opportunity to ask Josh where he was last Thursday between 7 and 11 a.m., and he's all, "Um, playing chess with Skye," and not "Um" as in "It's obvious that I'm lying" but "Um" as in "Let me think back." Where, asks Jim. Her place, says Josh. He lies a LOT better than Skye does, and he's on his way, but Jim looks way more suspicious. Possibly because "I got up at 7 a.m. to go play chess" is maybe one of the LEAST plausible things a teenage boy might do, let alone Josh, who you're always surprised doesn't suffocate to death by forgetting to breathe.
