OK, I'll stop now. This must be why I fell asleep at this part of the episode, to prevent my head from exploding from the medieval torture that is trying to patch the holes in this plot.
Fauxlivia asks how many locations there are. Astrid says she hasn't finished plugging in all the numbers, but so far there are twenty-two, and Peter asks where the closest one is. I'd probably have asked, "Who's up for Buenos Aires!
Oh, Jersey City. Booooo! There's a massive dig site underway as Peter strolls up with some coffee for Fauxlivia, asking what he missed, and he hasn't missed anything but a buried football, and then there is some allegedly cute banter that I will ignore, and then Fauxlivia looks over at Walter anxiously watching the dig and asks, "What if he's right?" and Peter's all, "Right about what?" Duh, about whether to build the doomsday device. "What if it does mean the destruction of one universe or the other?" asks Fauxlivia. Peter considers his answer before replying that they don't know that yet, WHICH IS WHY SHE SAID 'WHAT IF,' PETER. "If you knew that only one of our worlds could survive and it was up to you, and you alone, to defend your side, you'd have no choice, right? I mean, you would have to do what you had to do. No matter the cost to protect our world," says Fauxlivia, haltingly. Peter says some stuff about billions of innocent people being over there, just like here, people with jobs, families, lives. Yeah, people like Peter's MOM, which I'd think would be relevant, but he doesn't mention her. "Whatever my part in all of this is, I got to believe there's another way. There's always hope, right?" Fauxlivia looks at him for a while until one of the diggers shots that they've got something.
Peter, Fauxlivia and Walter rush to the edge of the big dig as the crane hauls up what appears to be a huge baked potato, dripping wet.
Back at Harvard, Astrid is still plotting the co-ordinates, placing flags on a map of the world for all the locations. She's about to stick another one in on the eastern seaboard of the U.S. when she stops and says, "Oh my."
She calls Olivia, who's watching as workers brush away the dirt encrusted the top of some sort of hard, flat surface, with a couple of strange symbols etched into the top.
