Peter's all NO WAY, and Olivia threatens a mysterious phone call again, and goes so far as to pull her phone out of her pocket, and Peter acquiesces. "You wanted my father. Now you've got my father, which falls under the category of 'be careful what you wish for.' Sweetheart." He stomps off.

Peter signs out his dad, who's chopping away at his beard in the bathroom. Maybe you could shave after you save John's life? Eventually, Walter's ready, and he steps forward, looking apprehensive, ready to rejoin the outside world.

Road trip! Woo! Olivia plays fun games like Grill the Nutcase, asking Walter if anyone else ever had access to his work. "My assistant had bits and pieces. God, I suppose." Other than that, the only person who really knew what he was doing was William. "William who?" asks Olivia. "Bell. William Bell. We shared a lab," says the doctor offhandedly, throwing both Olivia and Peter for a loop. "You shared your lab with the founder of Massive Dynamic," says Peter, but Walter doesn't know what Massive Dynamic is. "Nothing, really, just a tiny little company," say Peter sarcastically, lamenting that one of the lab partners became one of the wealthiest men in the world, while the other becomes an "institutionalized psychopath," like try being MORE of a dick to your father, Peter, first of all, and second, NICE RESEARCH, OLIVIA. I can't imagine how you compiled all this info on Walter Bishop but somehow missed that he used to work with this universe's Bill Gates. I mean, really. Oh, and then Walter pisses his pants. "Just a squirt," he says defensively. And then they pass by a billboard for, of course, Massive Dynamic. "What do we do? What don't we do," reads the slogan, juxtaposing a kid playing with a toy airplane, with a jet. Oh. So it's one of those companies with cryptic ads that are all "At Massive Dynamic, we don't make the television. We make a special type of glue for the laser welders used to put the components in the television" or whatever, which always makes me yell, "JUST TELL ME WHAT YOU WANT ME TO BUY" at the television.

Back at the hospital, Charlie's just dropped in to see what condition John's condition is in, and Olivia says he's worse. "CDC says the Hamburg flight was caused by a synthetic compound, which is like saying rain is caused by a wet compound." Charlie wants to know what's up with Bishop.

"Left to right?" says Olivia, whatever that means, adding, "Insane. And irritating. And also my only hope." Isn't that the tagline for every Pauly Shore movie?
