Back at the lab, Astrid's on the phone with Broyles, who lets her know that Amanda's body was stolen before it could be cremated. "And the funeral home covered it up. Apparently, stealing bodies is not all that unusual," she tells Walter. Does she expect Walter of all people to be surprised to hear of grave-robbing? He points out that the theft of corpses is a "time-honoured tradition" in the fields of science and medicine. "My dear, we've been stealing from the dead for as long as we've been burying them," he says, telling her that in the 19th century it was the most common way doctors and scientists had for getting cadavers to study. "In fact, the practice was so common that it inspired the gothic novel Frankenstein. You may have heard of it." This sounds kind of like the thing they do on Law & Order for legal reasons, where the lawyers or cops explicitly refer to the real-life case that the episode is based on to add a little layer of legal protection. Only this is Fringe, so the real-life case is Frankenstein.
Anyway, Astrid asks if Walter believes the dead can be brought back to life. He doesn't, but it's not for lack of trying on his part: "Belly and I dabbled in that arena for years. But alas, we never could revive Yatsko," he says. Astrid looks at him. "Peter just loved that cocker-spaniel," he finishes, and Astrid's face wrinkles up a little. Anyway, looks like the rigor mortis is setting in, as Walter looks over the corpse. "Feel that. Finally some stiffness," says Walter, and I think this scene got cut off too soon because obviously Astrid would have added, "That's what she said."
Elsewhere, Peter and Olivia are going through the stacks of files on the groups Amanda was in and the people she knew, having already removed anyone who doesn't have a medical or a scientific background. Peter's got one: Ellis Rourke, from the General Depression group, which he was in with Amanda for almost a year. Age 36, majored in biology, has an anger-management problem, arrested twice for battery. Olivia rejects him because she thinks whoever's doing this isn't driven by anger. Peter gives a slight eye-roll as he tosses the file aside, and an FBI agent comes in with more patient files from Col. Broyles, and I guess now everyone is going to call him Col. Broyles to remind me what an idiot I am. Anyway, Olivia says Amanda was also in a cognitive behavioral group that focused on ways to cope with depression. "You'd think that someone who was working that hard at being OK would get some sort of payoff," says Peter, who probably means well but displays a sadly common misconception of depression, and Olivia quietly says it doesn't always work like that. Anyway, Peter picks out another file: "Simon Whelan, age 29. Says here that he is socially and sexually incompetent," he says, but Olivia dismisses that one too.
