Walter's still in the car, playing with the seat warmer. "I've never seen a feature like this before. It warms your ass! It's wonderful!" he tells Broyles, after the agent walks over to the car. Broyles just stares at him, thinking, "I might just owe Nina a Coke after all."
Broyles walks them through the hospital, telling them about the Jane Doe who showed up on the hospital doorstep, pregnant to term. Died on the operating table, and two minutes later was a new mother to a baby, convulsing and in obvious pain. Doctors put him in a bassinet, and were transporting him when they realized they could see him growing before their eyes. "Growing ... you mean they could see it getting larger?" asks Olivia. Nina wouldn't be questioning Olivia's qualifications if she could see her kick-ass dictionary definition knowledge. She asks where the baby is now. Broyles leads them out into the hall (Peter has to hustle Walter, who's studying Loraine). Broyles explains that the baby died after half an hour, of natural causes. Olivia's all, huh? Broyles says the baby wasn't just growing, but aging. And a couple of crime scene guys are just finished up with the bloody body of an old man in a hall doorway -- still with an umbilical cord.
"We're supposed to believe that Grandpa here was born four hours ago," says Peter, while his father, fascinated, crouches down for a closer look. Broyles asks him if he has any ideas. "Celermitosis," says Walter. "Disabling. Reversing cell cycle inhibitors." More vaguely science-sounding things. He says he'll need to run extensive tests, with the bodies in a lab. He asks for one, and Broyles is surprised Walter doesn't remember that they've reopened his old lab at Harvard. Walter's momentarily embarrassed by his memory lapse, but then recovers to call that fantastic news. Peter wants to know why, even if all this is true, what they're doing here.
Broyles waits until they're all the way back at the lab to answer Peter, telling him about the recent inexplicable series of events being called "the Pattern." "Mr. Boyles, I consider myself a fairly intelligent guy, but I'm not following you here," he says. Olivia offers up a "weird shit be happening" stab at it, but then they're interrupted when Farnsworth comes in to say the hospital got a call from someone at the motel wanting to know if the pregnant woman was OK. She was there with a Caucasian male in his twenties. Wow, look at the team swing into action! Olivia tells Walter, who seems to be doing some tests on Loraine, that she needs him to take some samples at the motel, and he ignores her at first, then rips her head off, because he can't figure this out "with a girl buzzing in [his] ear." Peter says he'll take care of the samples, because his "limited stint" at MIT did teach him something.
