Meanwhile, Peter and Walter are no closer to the Towers, which loom even larger than they ought to in the distance, as Peter notes. "It's Olivia's mind assigning importance. Our surroundings represent her emotional landscape, don't forget," says Walter -- and now they got trouble.
He notices a creepy guy across the street staring at them. It's Olivia's stepfather, and Peter and Walter duck around the corner, because that's going to work. They peek around, and the stepfather is still standing there glaring at them. Not only that; suddenly everyone on the street stops what they're doing and starts staring at them. Cars screech to a halt in the street and the drivers get out and stare. "Walter, I'm getting a bad feeling about this," says Peter. Probably because he saw Inception too.
So any suggestions? Walter says, "Run!" and Peter and Walter take off running, and the crowd chases them, and it sure is a good thing that there was no one on the street in the direction they were running. Still, they can't outrun the mob forever, so they grab a cab that's handily parked in the street with the keys in it and no driver. They haul ass down the street -- not a lot of traffic on the streets in Olivia's mind -- and are chased by a couple of dark sedans that force the Bishops onto a cross street that takes them out into a calmer area of the city. They screech to a stop, and when they get out, Walter excitedly says, "Peter, I made a skid!" Please GOD he'd better be talking about on the street.
And now they're in the lobby of the World Trade Center building where they see Nina Sharp among the hustle and bustle, and Walter says she's a sight for sore eyes. They explain they think Olivia is somewhere near the top floor, likely in Bell's office, so she leads them to the elevators, and she tells them this special elevator will take them right there, and Peter looks suspicious, and Nina runs her card through the reader, with her arm looking very android-y. The doors open, and Walter heedlessly plunges right ahead and would have stepped right into an empty elevator shaft had Peter not grabbed him, and I'd just like to add that empty shaft or no, when are people going to stop doing that head-down-stomp-right-into-the-elevator-without-waiting-for-people-to-get-off-first thing?
