Time for Peter to step in, and he tells her that he saw how she was with Etta, and he knows how much Olivia loves her. "I'm not telling you to forget it, but the past is the past," he says, urging her not to let it get in the way of the second chance their family has been given. Plus, Etta's all grown up and Peter and Olivia didn't have to worry about socking away for a university education and she's pretty self-sufficient! Etta comes traipsing up to the van to finally tell her parents that the Observers are tracking them.

Back at the camp, Walter is welding something onto his Mythbusters suit when the Bishops arrive, Olivia asking how long until the suit is finished, because the Observers are on their tail. That sets Edwin off, all "You need to leave" this and "You need to go now" because there are only three roads the team could have taken after the spot where the Observers spotted them. But Walter says he needs just one more thing for the suit: copper, which Jonathan Barkley (I don't know his real last name, so I think "Barkley" will work for everyone) is available at an encampment down the mountain that trades metals.

Edwin's not hearing it, though: "We have until morning, at best, before they find us. They'll destroy everything. All of our work will be lost," he says. Walter suggests going to the camp, but Edwin tells him to forget it: "Those men are dangerous, and they won't trade with anyone they don't know."

By this point, the discussion has drawn a crowd of treepeople, including River, who reminds his dad that he's talked to them on the radio. Edwin admits it, but tells the Fringers that it only happens when it suits them, they don't even know who he is, and they sure as shit don't want people going into their quadrant.

The Fabulous Bishop Boys start tag-teaming Edwin, with Peter offering to go with Edwin as an armed escort and Walter suggesting he can barter antibiotics and medicine. Edwin tells them to go back to Boston, make the suit there and come back when it's safe, but Etta says the "Baldies" took away this Donald person when he took some rocks, so if they come here and read Edwin, they'll seal the mine permanently. Yeah! Just like they didn't do last time either!
