In the Fringe lab, Walter's sawing off the jaw of the burn victim, and Astrid remarks that it's amazing the sort of the things you get used to, working with Walter. Like hypodermic needles in the neck? I probably would have requested a transfer. Astrid takes the lower jaw (saying, "Wow. Looks like somebody could have flossed better") over to a computer where she's going to try to match dental records on file. Her use of the word "file" gives Walter an idea that maybe he put the manifesto in his filing system. "You mean like how you sealed things in the walls of your old house? Or how you squirrel things away in random deposit boxes around the country? I would hardly call that a 'filing system,'" says Astrid, and Walter says he hid things because he didn't want someone to unlock all his secrets, and maybe someone should remind Walter that most of the cases they've looked at involved someone carrying on his work, so maybe a better system is in order.
Anyway, he's looking for his Geiger counter, which concerns Astrid, but he says it's merely because the rhythmic ticking helps him think. Well, that's news to everyone. Guess he hasn't had to think up until now. Oh, no, the real reason he's looking for it is so that Astrid can tell him Peter cannibalized it for his project too, like WHAT IS PETER'S DEAL wrecking all the lab equipment? I'm just going to assume by "cannibalize," Astrid means "sold for crack." Not surprisingly, this sets Walter off on a tirade about how you do not take Walter's equipment without asking, and thank god Astrid can shut him up by saying they got a match on the victim. She pulls up the New York State driver's licence for Susan Pratt.
So Olivia and Charlie are let into Susan's apartment by the building superintendent. Charlie rattles off the particulars: 29 years old, single, worked for the New York Highway Department as a tollbooth operator. "That's a lonely line of work," says Olivia, who lives a life of parties in her brownstone.
Olivia looks at the books on the shelf, which include, ominously, Arthur C. Clarke's Childhood's End, and something called The Peter Prescription, like NO THANK YOU, but actually that's written by Dr. Laurence Peter, who said, "In a hierarchy every employee tends to rise to his level of incompetence." Yeah, that sounds like Peter.
The apartment bears out Olivia's "lonely," remark, as it's only furnished for one person. Little kitchenette, etc. Charlie asks if Olivia thinks there was something wrong with Susan. This would be besides SPONTANEOUSLY COMBUSTING? What Charlie means is she was a good-looking woman in the prime of her life, with no evidence of a boyfriend, or any friends: "Just doesn't exactly strike me as being normal." Since the death of John Scott, that could easily describe Olivia is well, but she just says it depends on what the definition of "normal" is. Translation: shut up, Charlie.
