Broyles asks again what they stand to gain from this, and Walternate tells him that while they have discovered some ways to cross to the other side that come with dangerous consequences, Olivia can cross without harm. "The Science Division is working up a series of experiments. We need her to submit willingly, which she'll only do if she believes that she belongs here. Phillip, if we can learn what she already knows..." says Walternate, and alt-Broyles finishes for him: "...we can begin to defend ourselves."
Walternate gets up to go, but alt-Broyles wants to know what happens if Olivia's new identity doesn't hold. "Then she'll no longer be necessary," says Walternate. Which means ... you'll let her go home, right? Right?
Now the alt-Fringe team is on its way to a case, with alt-Charlie explaining that two mornings in a row, Liberty Metro buses have run red lights, killing two people. "Now, 'Lookers' ran the probabilities, and it's a statistical anomaly," he explains. They're on their way to the crash scene, and they don't have tons of information about yesterday's crash, since at the time it was just considered a routine accident, but they do know that the first victim was Cole Arnett, a 43-year-old hospital caseworker on his way to work.
So they arrive on site, with alt-Charlie telling everyone to get their oxygen, so the agents get out their pimped-out asthma puffers, but another agent reports that the air-quality in Hoboken is normal, so no oxygen is needed. Normal for New Jersey, anyway. Alt-Charlie says Agent Lee is meeting them on site and will be calling the shots.
