Peter asks where the lake house was. Fortunately the professor has it right at his fingertips: Reiden Lake. A giant exclamation mark appears over Peter's head. Over Olivia's head, a question mark.
Outside, she reminds Peter that when he showed up in this timeline, it was at Reiden Lake. She asks him what's going on, and he explains that seeing past, present and future at the same time is what the Observers do, and how in his timeline, an Observer saved his life at Reiden Lake. (I'm ignoring their product-placed electric car plugged into the outlet or whatever you'd call it.) Olivia asks if he's suggesting that an Observer is behind this and is using Neil. Peter's not sure, but he thinks they should take a drive. Fortunately, They manage to not chat about how amazingly far they're going to be able to go on a single charge.
Back at the Harvard lab, Walter's got his eyes closed, he's plugging his nose and he's got headphones on. Farnsworthbot asks Astrid what he's doing, and Astrid explains that he's thinking. "You care for him," says Farnsworthbot, and Astrid has to admit that yeah, she does. And now it's time for another babblefest from the Farnsworthbot, who's worried that she couldn't give her father what he wanted because of the way she is. Astrid looks like her heart is breaking, like mine is. "That he secretly wished I could love him back in a way that he could understand." As the tears start to roll down her cheeks -- Jasika Nicole not wasting a rare showcase for herself -- she asks if Astrid thinks her father would have loved her more if she were more like Astrid, if she were normal. Astrid doesn't answer before the Farnsworthbot announces that she'd prefer her coffee with sugar. She goes to get some, while Astrid sits there, hoping Farnsworthbot cheers up again really soon.
Meanwhile, Peter and Olivia have arrived at Neil Chung's lakehouse. While Peter stares at the lake where, for all intents and purposes, he was born, and then goes to peer in the window, Olivia picks the lock, covering herself with a fake-innocent, "Who leaves their door unlocked when they're not home?"
