Back at the lab, Walter is dropping some liquid into a test tube filled with an opaque white liquid. Gene is mooing, which she only does when it's appropriate, so I guess it's milk. I like to think that Gene is on set every day but only gets lines in some episodes, and she has a trailer that she waits in, and scans the script looking to see if she has any lines that week.

Anyway, Astrid wants to make sure that Walter's not giving Gene any of the liquid to drink, and he says he won't until he understands the long-term side effects. "But imagine the possibilities if this can permanently erase cell decay!" Well, for starters, milk and cheese that don't go bad. And, well, probably immortality, right? But let's stick with the milk and cheese.

Anyway, Astrid's got a big box with "Yatsko Project" slapped on the side, and Walter was right, that they were misfiled: "It turns out that the research that you and William Bell did on human-tissue preservation didn't stop when you went to Saint Claire's," says Astrid, which Walter thinks is "fascinating" despite the fact that just about every episode for a while featured a case involving someone who furthered Walter's research. He's got a hypothesis, though, and needs Astrid to get him something. Not much. Just what's left of the organ donor's body.

Peter and Olivia are talking to Amanda Walsh's mom right now, actually, and seem to have just filled her in on what's happened. "Oh, god. The only consolation I had was her passing gave other people another chance," she says. Well, too bad we had to ruin that for you. Olivia asks if Amanda was dating anyone or if she had any friendships that were cause for concern. Peter twitches noticeably when Olivia says "dating anyone." Mrs. Walsh says that in fact she didn't have any friends, didn't like school, didn't want to do sports. "It was ballet. That was the only thing that ever made her happy," she says. There's a framed picture of a girl in a leotard on the table near Mrs. Walsh, who, when asked by Peter, says Amanda killed herself and had been clinically depressed. "She was on anti-depression medication. She also did a lot of group therapy. She kept trying different ones, but there were a few that she stuck with," she says. Olivia asks for the names of the doctors and the groups, and meanwhile Peter's phone rings. It's Astrid, because she needs to demonstrate the video-chat capabilities of a particular phone whose company hopefully paid a lot of money to earn such a jarring product placement.
