The Observer is briefly distracted by Markham cowering under his bed, and then is shot by Etta from her seated position on the floor. She seems to have recovered nicely.
Downstairs, Peter's alarmed by the sound of sirens, and when Etta joins him, she's surprised that Walter isn't there already. But with a jeep full of loyalists pulling up and shooting at them, the three of them don't have much choice but to haul ass out of there. "What are we going to do about Walter?" asks Astrid, and Etta and Peter just look at each other.
Walter's still stumbling through the apartment, when he finds himself surrounded by loyalists, pointing their guns at him. He puts his hands up. Glad you stayed behind for that Isaac Asimov paperback now?
After a commercial break, the remaining trio have made it back to home base and Etta and Peter are doing that complicated two-person thing to send Olivia shooting out of the amber, and she goes flying against the wall, and you'd think by this point they'd think of maybe PADDING the spot where the ambered person is going to be thrown to, or at least find a spot with fewer protrusions like the coat hooks on that wall, like Olivia's lucky she wasn't instantly lobotomized.
Peter rushes to her side and to give her the special de-amberization injection of whatever and to tell her she's in the year 2036, and she says she ambered herself. "We all did," says Peter. Then Olivia spots Etta standing behind Peter. She looks back at Peter. "I found her," says Peter, before correcting that to the more accurate "More to the point, she found us."
Peter calls Etta (sweetly calling her "kiddo" to come over to meet her mom), and Etta comes over to crouch in front of Olivia. The two of them stare at each other, eyes wet. "You're beautiful," whispers Olivia. Good genes, damn. "So are you," says Etta, crying. Olivia says the last time she saw Etta, she was three years old. "All this time, I thought it was four," says Etta. Olivia, hugging her daughter for the first time in more than 21 years, says, "No, it was three years, one month, five days."
