Gabriel is trying to stammer out backstory to Olivia when Vreede comes up, looking understandably alarmed at his colleague's wife just smiling and nodding at this surprise madman in the hall. Gradually, Olivia and Vreede tease the story out of Gabriel: He was part of a mass experiment where "Every other day for two years, we came in here. They put us to sleep. I never knew where I'd end. Sometimes it was a short trip -- I was eating a tuna sandwich, cat jumped on the table, kitty likes tuna -- sometimes it was long trip. He watches from [the corner], the doctor Frost. He told us we were special, 'cause we could remember things, everything. And when we came back, we had to write it down, every little detail." Vreede realizes that Dyson Frost inflicted these savants with hundreds of flashforwards. Gabriel says, "When they finished with us, when they used us all up, he told them to kill us so we wouldn't tell." Vreede leans in and says emphatically, "He's dead now. You don't have to be afraid of him anymore." Gabriel smiles with relief and says, "The early worm catches the bird. I've been waiting. I've been waiting --" "Gabriel, why have you been following me," Olivia says, treading all over Gabriel's long-overdue emotional catharsis. He tells her it's because she's going the wrong way and he has to turn her around: "In the futures I saw, I always saw you, Olivia. And you're always with Lloyd! In Harvard, by the pipe shop -- I tried to smoke that day, but I threw up. And we were friends. We were friends because I was the janitor in --" "No! Gabriel, I didn't go to Harvard!" Olivia says. I must admit: nice writing here, because it calls back to the Olivia/Lloyd scene where Lloyd explains the multiverse theory and Olivia admits she turned down Harvard Medical School for a life with Mark in California. Anyway, Gabriel is very, very adamant that Olivia is supposed to be with Lloyd, so she needs to fix her future stat, and the petty part of me is very, very glad that the universe is all, "Oh, Mark's a mistake." But there's another part of me that's all "Really? The fate of the universe depends on whom Olivia's wed to? Isn't that a little beyond believing?"
Mark is dropping the QED ring on Simon and Lloyd to ask them what in the Sam Hill the bling is. Janis helpfully points out that Suspect Zero (whom we all know to be Simon) was wearing one, too, so Simon seizes the chance to be perceived as a useful genius by just telling everyone it's the quantum entanglement device. Lloyd looks like he's beheld the holy grail; kudos to Jack Davenport for conveying the pure excitement mixed with scientific curiosity that Lloyd would surely have. Lloyd turns to Mark and says, "This is what we were discussing in our flashforwards." Wedeck demands some exposition and Simon lays it out: "Theoretically, Frost and his pals ramped up our linear accelerator to such extreme energies that it send shock waves through the consciousness field, and jolted all of humanity's awareness to a different place in space-time -- the flashforward. Our Suspect Zero and Frost were awake during this. They were in some way protected." And this ring is how. Lloyd says dreamily, "It's a device which anchored their minds to their current location in space-time." Wedeck is incredulous about the powers of the ring, but that's only because he's never seen any of the Lord of the Rings movies and doubts the power of finger bling. Mark figures the people he saw in his flashforward were not coming for him, but for the QED. Wedeck says, "Well, now that we know that, we can figure out a way to stop them." Yeah, good luck with that -- you've got Janis sitting right next to you and, let me remind you, SHE'S A MOLE. As if to underscore my point, we go to Vogel looking all skeptical and Janis looking appropriately evil.
