Orson looks out the window of their house and says Sam's still out there and she should talk to him. Right, the creepy stalker outside your house? Talk to him. Bree says she has nothing to say to him, but Orson says he's 26 so was born before she married Rex. She says fidelity isn't the issue; it's Rex's secret life. Orson thinks it's fine to be mad at Rex, but not at the innocent young man. Bree says he showed up at work and didn't tell her who he was. She wonders what he wants, and Orson says there's only one way to find out. Bree goes outside and tells Sam he has two minutes to explain. (What's with everyone and the two-minute limit?) He tells her that his mother and father met at a bar, when they were both single. They had one night together, and she called him when she found out she was pregnant, but he'd already met Bree and was in love. He offered to support her, but his mother turned him down. Bree asks if he visited, and he says a few times, but his mother asked him to stop because it was too hard on him. She asks if he ever saw him again, and he says he did, from right here. He'd ride his bike by as a kid, and wonder why Rex would choose all of them over him. He says he could see they were perfect. And when his mother died six months ago, he decided he needed to meet Bree. She asks why he didn't tell her, and he says he wanted her to like him and wasn't sure she would. She says he looks cold, and hugs him, then invites him in for hot chocolate. It's very loving, but Andrew's watching angrily from his window. Maybe he should find his missing doctor boyfriend and stop the obsession with his mother.
Katherine's reading a book with no cover title, so ... her own diary, I'm guessing? Anyway, Robin comes back from her weekend wedding, and says she caught the bouquet. No pressure. She tries to kiss Katherine, who turns away. Robin asks if they need to talk, since they haven't. Katherine tells her she's a wonderful, beautiful person, and Robin says, "Oh, yowza." Katherine tells her she was drunk, and the other night was a mistake. She's so sorry. She picks up her book again, but Robin tells her that's complete crap. She's not going to let her blame it on being drunk. Katherine tries another excuse: She's been through a lot recently and was trying to forget that. She says she's not attracted to women, so it doesn't count no matter what. Robin says she knows how Katherine touched her and how she liked being touched. She says she might deny it now, but they connected and it counted. She kisses her, and Katherine kisses back. She says, "Okay. It counted." Robin thanks her, and they smile at each other. Not sure if that means it's the end or the beginning.
