Back in the office, Charlie is whining about how Westford is thirty square miles, so how are they supposed to find one field? Olivia, looking at the map, has it already: "There's an abandoned air strip out there. It's called Little Hill Field." "Little Hill" is the codeword Joseph Smith (not the father of Mormonism) gave to David Jones a few weeks ago. "It can't be a coincidence, Charlie," she says. She tells him to come in from the west, and she'll take the south. Charlie starts to yell again, which I think he really likes to do: "I need every available unit for field assist! Let's move, move, move!"

Back at the lab, Walter's looking through his files to try to find out what he hid in the boxes. "I kept very thorough records," he tells Peter, who throws a book down in frustration. "Unfortunately not very organized records," he says. He sits down and starts flipping a coin across his knuckles, which his father calls impressive. What's even more impressive is how Peter's arms and torso have been replaced by someone altogether, wearing the same clothes. Peter calls it a nervous tic, and then he makes the coin disappear and asks Walter to pick the hand, because ten episodes in all of a sudden Peter is David Copperfield. Then Peter notices his dad staring gravely at him, so we know we're going to be walking down memory lane with Walter. "You nearly died when you were a boy. You started bruising, and your kidneys failed," he says. Just once, can't it be a funny story about something Peter said at a family reunion? Walter says the doctors didn't know what it was, and their closest guess was hepea, which is a rare form of bird flu that hadn't been around for decades. Peter's mother was beside herself, and Walter was even worse, because he's a scientist, and he can't do anything about his son dying. "Walter, I don't remember any of this," says Peter, but Walter's on a roll now, talking like he's only just remembering it. He says he became obsessed with conquering the disease, and discovered a doctor, Alfred Gross, who was the only physician to ever successfully treat hepea. But he died in 1936.

The music's swelling to kinda ridiculous levels as Walter says he designed a device to "reach back in time, to cross the time-space continuum and retrieve Alfred Gross. To bring him back with me, to fix you, my dying son." Walter thinks the device is what's hidden in the safe deposit boxes. Peter, realizing that he is in fact alive, asks his dad if the device worked: "You were able to go back to 1936 and get this guy," he says. Walter says before he could test it, Peter started to recover on his own. "But the science behind it, in theory, it would work. In theory, it could retrieve anyone from anywhere," says Walter. To borrow a phrase from Peter, I just want to see if I understand this: Walter built some sort of time-teleportation machine, but because Peter got better, he NEVER TESTED IT? Of course, this was right before he went to the mental hospital, I guess, so... but still. I mean, Jesus. Should have used the time-teleportation machine to get yourself Clarence Darrow for the defense, Walter.
