Broyles' secretary brings in some sort of disc that she says has "the checkpoints" and he thanks her and says he'll be gone for the rest of the afternoon. Uh, not so fast, Philip: Windmark walks in, saying he wants a word with him. And we're into the opening credits again, which is odd since we didn't have closing credits during the last hour so I'd briefly hoped that the finale would be done seamlessly, but it's a little late to worry about that sort of thing now.
Anyway, Windmark, seated now, places his hat on his knee and asks (well... states is more like it) if Broyles is aware there was a Level One security breach today, resulting in the abduction of a high-value detainee. Broyles says he didn't, and dances around Windmark's insinuations about how the fugitives knew exactly where the prisoner was being held and the "whispers" that "the Dove" may be among them. He stares at Broyles for a few moments. Broyles smoothly says that if that were true, whoever it is should have been read and exposed long ago and stares back.
After a moment, Windmark stands up, almost smiling (now there's a red flag), puts his hat on and says he doesn't wish to keep Broyles from his duties any longer, reminding him to "remain vigilant" and giving his HenchObserver a significant look as he walks out the door.
Dontember is studying the holograph schematic for his device when the Fringe team makes it back to the lab and he's all, "Where have you been?" Hey, it's your kid who stepped off the monorail and caused all this, buddy.
So the grown-ups discuss it, with Olivia wondering why he would have done it, because he must have known the Observers/Loyalists wanted to harm him. Dontember says there was apparently a reason, because there always is -- and everyone has a look at Michael, who right now is amusing himself greatly by watching a television screen of snow. We're sure about this heightened intelligence too, right?
Anyway, Walter says Anil and his men have positioned the magnet as per the instructions and Dontember's all, "Yeah, about that? I need one more piece." The initiating reactor's core has decayed substantially over the last twenty years, so he enlisted some help to get another one from his time. Walter figures, correctly, that it's an Observer -- "One I trust," assures Dontember, but one of them will need to retrieve it, he says. Way to include yourself out from that mission, Dontember!
Walter explains that the reactor will provide a surge of energy to start up the device, which will generate a singularity -- a small wormhole -- and once it's open, they'll be able to deploy the cylinders and those will stabilize each end -- one here, the other in 2167. The magnet is used as the launch platform, holding the cylinder at the precise axis it needs to be on to enter the wormhole and the scrolls were to help them set the cylinders precisely. Look, quit pretending that there's some sort of logic to this -- it's OK, it really is. You think that the people who have stuck with the show this long need actual logic behind the plan to open a wormhole to a hundred and fifty years from now so you can bring a hybrid human-Observer to a Norwegian scientist so he doesn't destroy emotions for the sake of intelligence thus dooming humanity to a joyless albeit sartorially dapper future?
