Peter wanders into the lab from god knows where and asks Astrid (poor, poor Astrid) where his father is. She shrugs, because she was too busy on Craig's List looking for a real job to keep track of Walter. Olivia arrives at that point, also wanting to see Walter. Astrid and Peter get a little nervous then. As Astrid goes to check the cafeteria (off camera naturally) Olivia tries to tell Peter that David Robert Jones shot Nina Sharp, but Peter is in the middle of a phone call trying to track down his dad. No one knows where Walter is and Olivia starts to feel a little guilty about yelling at Walter at the pastry shop about the Cortexifan trials. Peter lets her off the hook way too easily for someone who made his old man cry, in public! He more or less shrugs, which I think is unrealistic considering the developing relationship between Peter and Walter. Peter is sure that Walter is just back at the hotel eating ice cream and reading US Weekly. So he's sulking. Or PMSing. Or maybe took acid again?
Cut to Walter not at all in a hotel room, but, rather, in a cemetery staring mournfully at a grave. In the woods watching him is the bald headed pale guy we'll call Powder in a shout out to a 90s film I never actually saw. Over at the hospital, Nina awakes to the unrelenting and intense gaze of Agent Broyles. As Nina stares at the damage done to her arm, and her fingers are wiggling like a bug on a pin, or what I assume a bug on a pin looks like, not having committed that particular atrocity myself, Broyles tells her that it was David Robert Jones. He wants to know what he did to her arm, but she won't tell him. Dunham, she wants Dunham. Well that probably hurt Broyles' feelings.
A black van pulls up on a rainy street. The Invisible Man gets out with his team. They set up a bunch of equipment in the middle of the street. They are in the shadow of the Williamsburg Bridge in Brooklyn, which is actually where they do nine-tenths of their filming, but let's just keep up the illusion that this show is filmed in Boston, eh? As a viewer who lives like five blocks from where they do all the bulk of their filming it is particularly annoying. Anyway, if anyone cares to stalk me and yell at me about my overuse of parentheticals, my house is five blocks from this scene and I buy coffee on that there street corner and my friend lives across the street and my aged Chihuahua has definitely peed on that lamppost. So there you go.
