Olivia asks what trajectory that is, and Peter says it's the trajectory that leads to his death. Technically speaking, I think we're every one of us on that trajectory. Anyway, Peter says at 5:12 tomorrow afternoon, he'll meet Windmark, who won't be expecting it. "At 5:13, I will snap his neck. At 5:14, he will draw his last breath," says Peter. He plans assassinations like my wife plans vacations! I mean, with less killing, but the precision is the same.
Olivia's all, Yeeeahhh, that's great and all, but I've lost you once already over this, and I'm not gonna let that happen again. She admits Peter's thinking is way ahead of hers: "But the fact that I am here has got nothing to do with anything except feelings. And soon, you're not gonna be able to feel anything. Not for me, not for Etta."
Peter tells her about Windmark showing him Etta's last thoughts, and how they were of them, that day in the park before everything changed. Really nice job by Joshua Jackson here, I think -- he's very much in control but you can see there's a little bit of feeling left. "I will kill him tomorrow. If I remove the tech, I will not be able to do that," he says. Well, not with that attitude!
Olivia wants to know if tomorrow is too late, and the tech becomes permanent? And apparently Olivia has done a complete 180 on her conversation with Simone, because she starts in on how Etta isn't dead and is still here with them and actually saved Olivia's life today with the bullet she brought them. "She's alive inside us. And there's nothing that Windmark can do about it, because the love that we can share with her now is invulnerable to space and time, even to them."
Peter is in the "Emotion is our weakness" school of thought, but Olivia says it's their strength, because it's the one thing the Observers don't have. Well, that and hair follicles. Olivia says they need to hold on to their connection Etta, or she dies all over again.
Peter checks his watch, and then turns to look as Windmark walks up the steps into the square. Olivia keeps talking, telling him that she's not asking him to abandon Etta but to hold on to her: "You're not one of them. You're one of us."
Flashes of that day in the park flip thought Peter's mind, and then Olivia makes him look at her. "I love you," she says. And then images of Peter and Olivia and Walter and even Astrid! and more Etta start shuffling through his head. Oh, it's a clip show? That's bullshit.
