But we cut to Peter's secret Harvard lab, where he shows her everything they know about the machine, every schematic, every piece of data and diagnostic. Olivia walks through the lab, and looks at the display of the Space-Invaders memory disks. "Are these..." she says, and Peter says yes, they're memory disks from dead shape-shifters. "How did you get them?" she asks, and Peter doesn't say anything, and she nods as she gets it. And while he's explaining that they're still working but the information is encrypted, Olivia seems a little discombobulated by a faint ringing sound. "I've run it through every code-breaking program that I know, but so far I can't break it."

And then Olivia, without turning around, says, "That's because the decoder key is in my office," and Peter doesn't appear to notice that Olivia's voice suddenly sounds like she's been smoking a pack a day for the last thirty years. "What? At the FBI?" he asks, and Olivia (Bellivia?) says, "No. At Massive Dynamic." S/he turns and looks at Peter. "Hello, Peter. It's nice to see you again." Gah! So: just when Peter and Olivia have worked things out and Olivia has gotten over her resentment at Peter boinking her alternative-universe doppelganger, she goes and gets herself possessed by the soul of an 80-year-old genius scientist. I hate when that happens!
