Then he reminisces about how the Observer told him "give me the keys and save the girl," and this is the first time Peter is hearing about this, and Walter has realized the Observer was preparing Walter for having to give his son up later. "Because he knew I would have to let you go. That I would have to sacrifice you to fix the problems I'd created," he says.
Peter thinks about this for a moment and then says he thinks this is what he's supposed to do -- but he can't do it without his father's help. He holds his glass up, and Walter clinks his against it, and they both drink.
Meanwhile, Olivia's driving to New York, whilst listening to K-Plot radio, your exposition destination, which is yammering away about unexplained weather phenomena up and down the eastern seaboard over the past 24 hours, as well as the storm warning that's in effect for the entire coast.
In New York, Nina is yelling at some flunky on the phone about how some person couldn't have just disappeared. There has to be a trail, so find him! she yells. Olivia arrives, and Nina tells her that she's assigned people as Olivia requested to the protocol she requested, and Olivia wants to know where they are in terms of coverage, and Nina's got satellites focused on the northeast states, which gives them some sort of thermal reading blah blah that will give them some lead time if a vortex starts forming in a densely populated area. "What about electromagnetic disturbances?" asks Olivia, and Nina says their cellphone towers have been recalibrated to detect them, etc. Has this all happened since this morning? Good God. Also: did Olivia really need to drive all the way to New York for questions that could have been answered over the phone? Like on one of the fancy product-placed phones that we know EVERYONE here uses?
Olivia asks about the amber, and Nina admits they've hit a wall and only have enough amber to contain eight, maybe ten events, but beyond that, their chemists are having trouble finding some of the more rare elements. Olivia snaps that without the amber, early detection is irrelevant. Well, I presume evacuation is still a goal, right?
