Walternate asks how she knows all this. Alt-Olivia: "I know it because I read it in the ZFT in 1995 when you wrote and published it," sounding like she's wondering if that's supposed to be a trick question. Walternate goes and fetches his own paperback copy of ZFT from the bookshelf. It's a very Dianetics-looking book. "ZFT. The natural decay of our world. What would you say if I told you that the ZFT is a lie? Or a half-truth, anyway?" The Fringe Division members try to contain their shock at the idea that a government might withhold information from its citizens, as Walter tells them the holes are man-made, and they don't simply lead to nothing. "There is something on the other side," says Walternate. Alt-Olivia doesn't get it, but Lee does: "Another one." Walter: "Another universe. A parallel Earth just like this, but slightly different. And it was their attempt to penetrate our world which created the pattern of destruction that we struggle with daily." "Pattern," hey?

Speaking of slightly different, to the right of the Fringe team, hanging on the wall is a huge map of the United States, albeit one that is different from our universe's: to my non-American eyes, I pick up the following things: Texas has been divided into North Texas and South Texas, the Dakotas are one big state, and something's been eating away at the coastline of California.

So both the $20 bill and the man came from the other side, and Walternate figures he didn't come alone. He says he's not a "lover of war" -- and really, what politician would ever admit to being a "lover of war"? -- but he thinks the invaders are anything but peaceful. "They must be found, and they must be found quickly," he says, and Lee promises that they'll get the dirty rats.

Meanwhile, the original Fringers are hanging out by a bus stop advertising a new season of The West Wing, with a poster featuring actors who could very well represent Sarah Palin, John McCain and Barack Obama. Yeesh. I think you'd want to stick with the original cast. Anyway, Sally is "burning up" -- her words.

The bus arrives, and Olivia's the first to get on, only to see a sign demanding that all passengers scan their "Show Me" ID. Olivia makes a show of looking for it and then realizing she forgot it, and then she gets off the bus and tells everyone that they're going to have to walk. "Central Park is 59th Street. That's three miles from here," protests Nick, which is all the more reason -- as Olivia points out -- to get going.
