Meanwhile, Astrid, Peter and Olivia have turned up at Cedar Street, which of course looks a lot worse off than it does in the video. "You sure this is the right place?" asks Peter. (Like, take a look around you, Peter -- all of Boston is one giant fixer-upper now.) Astrid shows him the original, untouched façade on the video via the viewfinder on the video camera, which they've brought along and which I think I can guarantee is a much more modern home video camera than anything that ever produced Betamax tapes.

Meanwhile, like the first draft of a crappy Lionel Richie song, Cecil and Walter are walking on the ceiling. Walter's quite tentative as he steps over doorframes and around ceiling light fixtures, but Cecil assures him he won't fall. They make their way down the upside-down corridor to where water dripping from the ceiling is being collected in a little bowl on the floor. "I've managed almost half a cup every night," says Cecil, pulling the bowl from the floor and taking a sip. Walter looks at the wall and thinks there's some kind of refrigeration unit or something causing the condensation. Cecil says he's been all around the place every which way and there's nothing on the other side of the wall. As you can imagine, that's not good enough for Walter, who wants to have a look for himself and he tells Cecil to follow him.

Walking faster now -- it helps they're on a proper floor again -- Cecil and Walter stride down a hallway, with Cecil demanding to know how it is Walter knows his way in and out of here. Walter says it's because he's been here before, but he just can't remember it. I'm sure that clears everything up for Cecil.

The rest of the gang are following in Walter's footsteps, and are surprised Walter apparently negotiated the stairs half-blown apart by the hole in the wall. "Walter's full of surprises today," Peter says, darkly. You should talk, Peter. Really, at this point, they're assuming Walter even made it this far, instead of, you know, getting rounded up by the Observers and Loyalists who are supposedly on the lookout for all these fugitives.

Anyway, Cecil and Walter are still walking around, with Cecil saying he thought they were getting out of here. "Not until I find what I came for," says Walter, barely paying attention to the guy. "For a while, I thought this was purgatory," says Cecil. Yeah, J.J. Abrams gets that a lot.
