Doc's Comics. The "pro" Doc was talking about turns out to be Chet, the stock boy. Somehow, he's managed to find the house using a laptop. It's in Daly City. They still don't have a street name, though, so Doc proposes they look up old census reports.
Sub-Hub. Hauser asks his crack team of nerds whether there was any seismic activity the day the guard returned. Instead of answering, one of the nerd asks, "Sir, do you think the keys, Tommy Madsen, the jump--that they're all related?" He sounds incredulous, but I can't fathom why. I mean, isn't this what they've been assembled for? "Humor me," Hauser says. One of the nerds says there was something "statistically insignificant along the North Hayward fault." Hauser thinks out loud: "The guard is looking for Madsen, which suggests that Madsen is unaccounted for." "Or lost," a nerd suggests. "Or lost," Hauser repeats, in case you missed the first time.
Doc's Comics. Rebecca and Doc go over an old census report. Rebecca reads an entry for the Madsen household aloud: "William, head of household. Laura, spouse. Tommy, son. Ray, son." She's a little surprised to read the last. "They were brothers!" Doc figures Ray must have changed his name to get a job at Alcatraz because they wouldn't have hired him if they'd known he was related to Tommy. "Ray's my uncle," Rebecca says. "My real uncle!" She's so much more shocked by this than by the mysterious appearance of eternally youthful Alcatraz inmates. Also, why wouldn't Ray have told her his true identity? It's understandable why he'd lie to Alcatraz officials, but why his own family?
Flashback. As the prisoners return to their cells, Ray and Guy make sure that Tommy is stuck outside his cell when the doors close. The other inmates start chanting in anticipation of a fight. Ray walks over to Tommy and bashes his head against the bars of his cell door. Tommy doesn't put up much resistance. He falls to the ground as Ray keeps on punching him. Eventually, Guy pulls him off and says he's made his point.
Daly City. Ray brings Guy to the old family home, which is kind of a dump nowadays. Tommy isn't there, but Ray insists he'll show up.
