Speaking of Olivia, she's at home, going through her closet, and we learn that she shops at a place called Everything Black and Grey, and then she looks at herself in the mirror and touches her Fauxlivia tattoo on the back of her neck. Then she starts yanking clothes off the hangers. No plastic or wire coat hangers for Olivia! All wood, baby! She gets angrier and angrier. And she yanks sheets off her bed and takes them to the little closet that houses her washer and dryer, and discovers a load of clothes that Fauxlivia had left there, apparently without even washing because Peter's MIT T-shirt is there and it is magically dry and unwrinkled. She dumps it on the floor, and then breaks down crying, crouching in front of the washer. I suppose it could be worse: what if Fauxlivia hadn't done laundry at all?
So the next day Olivia strolls into the break room where Astrid has just made a fresh pot of coffee. "Bad night?" says Astrid, because Olivia seems like death warmed over, and Olivia just says she had a lot of laundry to go through. Astrid asks her how it is to be back, and Olivia says it's good, except for the whole Peter-sleeping-with-Fauxlivia part.
She asks Astrid what Peter was like with Fauxlivia, and Astrid seems really awkward. "He didn't seem different? I mean, like, happier, or..." and Astrid seems awkward enough that Olivia gets the hint and backs off, saying they should probably go because Broyles wouldn't have called them in if he didn't have something. She starts to leave, and Astrid stops her to point out that Peter thought he was with her. Olivia says it's fine. "It's not fine. Whatever feelings Peter had, they were not about her. They were about you. And they were real. They still are," says Astrid. It's a valiant effort, but Peter's already kinda tried it.
