Nina gets home, and who should be there but Skylar, busy with bits of Nina's electronics scattered all over the kitchen table. Nina thinks Skylar's just there to raid her apartment for materials. "Not exactly," Skylar says.
Back at HQ, Rachel is looking at the electronic bee Skylar left behind and wondering where it's transmitting its signal. Gary would come in handy, but obviously he's not in. Bill enters with the news that a car that was hotwired nearby after Skylar's escape just turned up outside Nina's apartment. That's some pretty speedy detective work and would be even more impressive if we viewers didn't already know where Skylar went.
She's not there any more, though. Nina's driving Skylar somewhere and, after a short argument, even agrees to ditch her phone so they don't get traced and nabbed. Nina wonders what's next. All Skylar will say is they're going "off the map," but first they have to kill Bob. Nina looks shocked, as though it's not immediately obvious that by the way Skylar is referring to him that Bob isn't a human. Not that Skylar cares much about humans anyway.
They make it to an "NSA Research Facility" in Cheshire Connecticut, and by this time, Nina seems to be on board with killing Bob, who apparently is the reason they keep finding Skylar. Skylar gets them through the automated security systems having, of course, designed them. But soon they're stopped by a uniformed security guard who's aiming a gun at them. "You ladies lost?" he asks, not sounding as helpful as he looks. I think we just found out why Skylar brought Nina along.
Cameron, Rachel, and Rosen have easily ascertained that Skylar was in Nina's apartment by the pile of microchips on the table (including the guts of the espresso machine that Rachel says she just figured out), and Bill says that Nina was seen leaving with Skylar in her car. Rosen says, "Let's go," although it's not clear how he knows where.
At the NSA building, Nina gets tired of being led at gunpoint and Pushes the guard into opening a door, waiting outside, and counting to a million. Inside the room is Bob, a supercomputer that can apparently track anyone on earth using satellites and people's bioelectric signature. Luckily there's a processing lag that allows Skylar to keep half a step ahead of her pursuers, although it won't be long before they catch up. They must only be able to track her when she isn't moving, because otherwise it seems like her Bob-ward trajectory would have been kind of a giveaway and there would be a small army waiting for her. She takes an electronic core that looks like a transparent Thermos full of blue lightning out of the machine and replaces it with another device that's counting down from ten minutes. That looks like it's a wrap for Bob.
