And then there's Original Olivia, peeking over the rows of seats, at least until Broyles hisses at her. They're hiding a short ways away, along with a woman and man. So when Charlie said, "Site's clear, boss," when Lee arrived, what exactly did that mean? All that technology and government authority behind the alternate-universe Fringe Division and they missed one whole dead guy lying on the floor and FOUR OTHER PEOPLE ducking down? They haven't mastered the concept of looking BEHIND things? They don't see OLIVIA'S HEAD STICKING UP? The four of them skulk away, Olivia looking particularly distraught at all the weirdness, and then the camera pans upward, through the skylight, to the zeppelin hovering overhead, and then out over the Manhattan skyline, prominently featuring the Twin Towers still in place, some building that looks like a cruise missile that I'm relatively certain doesn't belong there. I'm guessing there are other features out of place, but I hate those What's Wrong With This Picture? puzzles, so we're just going to head into the opening credits.

Which are red! And feature different technologies and phenomena! Hypnosis! Pyrokinesis! Hive mind! ESP! Neuroscience! Clairaudience! Cryonics! First people! Astral projection! Mutation! Protoscience! Genetic engineering! Have I ever said how much I love the theme music? It's true. I even bought the soundtrack, lord help me.

We're at Harvard University, 36 hours earlier. Our own universe. Walter's watching security footage labeled "Northwest Passage Motel Surveillance Tape," which shows Walternate strolling out into the hallway, followed by Peter. "I can take you back where you belong, son. They have our coordinates. But if you go with me, you won't be able to come back here." The Northwest Passage motel specifically? Or this universe in general? Peter thinks about it a moment, then says "Let's go," and they're gone. Apparently, judging from the episode synopsis that was on the Fox website for "Northwest Passage," that was a scene that was supposed to have closed out the last episode.

You are never going to believe this, but Olivia's drinking. She's even in a bar, which is great, because that means she can get other people to pour her drinks for her. Well, bottoms up, Olivia!

It looks like something's occurred to Walter, because he sits up and then starts searching through his files.

And at the bar, an Observer strolls by and drops a piece of paper on the seat next to Olivia, but she's presumably too drunk to notice. She only sees it after the Observer passes through her line of vision on his way out the door. She picks it up, while Walter back in the lab is still frantically searching through his papers, at least until he gives up and calls Olivia. She answers her cellphone, staring at the piece of paper. Walter agitatedly tells him there's something he's supposed to remember, but he can't, but he thinks it's about Peter. "I think something is going to happen to him. Something, something terrible." And Olivia looks at the piece of paper which features some sort of schematic for a huge device that looks like it requires a person plugged into it, as opposed to four D batteries. The device sits on five legs (perhaps six, if there's one directly behind the one in center front), and it's set amongst the ruins of city buildings. Below that, on top of lines of text (various combinations of the letters ATCG), is a picture of man's head, a man who looks a lot like Peter except for the fact that it looks like his eyes are exploding.
