The next day, Skye skulks around the entrance to the Eye before going inside, while a string quartet plays Scales of Tension. Inside, as usual, no one is using this amazing resource, so Skye goes in and plugs in the little USB key thingy that Lucas gave her, and says "Activate" and then all these formulae start floating around, none of which have anything to do with us.
Over at the market, Maddy is presenting a whole lot of junk to Casey Durwin, who is the legless bartering dude. He doesn't have any use for her frilly green scarf, old teddy bear and abacus. She collects them, but this is the only one she brought with her. (I find it amazing that out of everything she might take with her in a backpack knowing she was never going to see her home again, she couldn't find anything more important than an abacus.) She argues with him about how one man's trash is another man's treasure, but he tells her that what she needs is to find something that the other person can't live without. He says this just as we see his wheelchair has a bum wheel, so we know where this is going. She asks him if he would bargain for a new wheel, and he says that then they could talk. I would just like to know what kind of Colony of Assholes can't help out the only guy in a wheelchair by fixing his flat tire for him.
Skye goes to visit Lucas in his tent, covered with papers of equations, like a pre-electronic age Beautiful Mind. He calls her "Bucket" and asks her if it worked and does his own plugging-in whatever and starts creepily muttering about how he's so close, in a very brain-addled mad scientist kind of way. Skye says she recognizes the equations from the falls, but she never told Taylor because the area's off-limits. Lucas says their relationship is Shakespearean and like a Greek tragedy and I think he may have said those so the show can sneak a "Shakespearean!" into its print ads. She asks if he's always hated his dad. He hasn't always -- just since August 2138. "What happened then?" she asks. "Ask him yourself," he says. He's similarly unforthcoming when she asks what happens after the portal opens both ways, just shooing her out of his tent.
