But Ms. Donovan needn't worry, because Walter's got his best dropout con artist son preparing the syringe to stick in her daughter, who says it's nice to have someone not afraid of her. Peter asks what she means. "Well, my friends at church. When I walked past them, I could feel them all talking about me behind my back. Kids at school are even worse. Ever since what's happened, they think I'm like a freak or something." Wait, how much time has passed? Peter tells her that they're kind of partial to freaks in this lab.

Olivia strides into the lab and bellows out something about wanting to know how it's going, and I think she can be forgiven for thinking they're goofing around because Walter is MILKING GENE, for god's sake. And Lisa, who seems a little smitten with Peter, asks if Olivia is Peter's girlfriend, and Peter explains that she's like a "friend who's a girl. And who carries a gun." Which is kind of hot, actually.

And Olivia confers with Walter over the possibility of extracting Rusk's thoughts from Lisa's brain, and wonders if she'd be able to get Rusk to describe his last moments, because she wants to find out who killed him. He sucks back the fresh milk and decides to give it a whirl.

Peter straps down Lisa, which Walter assures Ms. Donovan is just a precaution, and Peter all sensitively tells her to tell him if the straps are too tight. Then there is sciencey talk of "six hertz" and "increase the drip two mikes" and Lisa's uncomfortable to the point that Ms. Donovan wants to stop, but Peter and Walter calm the two of them down, and Lisa closes her eyes. Then Olivia steps in to softly talk to her about Andrew Rusk, and then some needles on a graph somewhere start skittering wildly, and Lisa starts seizing and Ms. Donovan wants to stop and Walter says, "We have to let it run its course," which doesn't sound right, and then Lisa speaks in a possessed voice: "There is no Dana. Only Zuul." Ms. Donovan wants to know why Lisa's speaking like that, and Walter says, "Because the recapper has seen Ghostbusters like eight million times."
