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?
Anyway, Nina looks rather upset, and she blabs to Olivia: "I was told on good authority that if you and Peter were together, it would all work out." Olivia wants to know what the hell Nina is talking about, so Nina tells her about Sam Weiss (but she doesn't say Sam's name yet), whom Bell told her about and advised her to trust, and who knows a lot about the machine. Olivia's furious that Nina never thought to mention this before now, but Nina says Sam said if she divulged what he told her that she would never hear from again, and she didn't want to risk that. Olivia demands to know who it is, and Nina says, "You've already met him. Sam Weiss."
In another room she shows Olivia all the books she received under the The First People Book of the Month Club, and points out that the authors' names, even the Hebrew and Russian ones, are scramblings of Sam's name. Olivia's amazed, since they've been over those books hundreds of times. She wants to know what else Sam knows, and Nina points out that Sam reveals only what he wants to reveal, as Olivia well knows, but Olivia's not to be deterred, despite Nina saying they don't have an address for him, and the phone's been disconnected and the bowling alley shut down. That's unfortunate. In a time when the fabric of our reality is being ripped apart, humanity needs bowling alleys more than ever. Olivia vows to find Sam and stomps out of Nina's office.
Then we watch a young couple annoyingly chase each other through a field in Saratoga Springs, and Jeanie's got the truck keys and is playfully running away from her boyfriend, Jack, and they get in the truck and whatever little squabble that turned into key-keepaway dissipates as Jack says, "I meant that you mean a lot to me. You're kind of amazing," and instead of getting annoyed for the "kind of," Jeanie gives him the keys and they start making out. But before he can impregnate her (again, I mean), Jeanie notices something through the front windshield that concerns her. The sky is shimmering, in a prism of colours. Think of a rainbow aurora borealis in the middle of the afternoon, that's what it looks like. It looks like our young lovers will survive this for now, because we cut to another observer: Sam Weiss, who has one of those trans-universe viewing windows set up, through which he's watching what's going on whilst solving complex physics equations in a notebook. I have no idea what the equations mean, but the answer he arrives at is zero, which doesn't look to be good news.
