Triple H. Saul has come to check on Holly, who's distraught; seeing herself in Nora's eyes was a dreadful eye-opener. "It is time that I become a person. I won't be invisible any longer." I'm betting she won't be inaudible, either.
In the living room, I think, Nora's looking no happier than Holly as Kitty comes in and commiserates about how miserable the dinner was. Nora apologizes, but Kitty says the explosion was necessary, and I like that Kitty is the one comforting Nora here; their adversarial status makes her comfort mean more than Sarah's, and the boys are out of the question in this particular situation. Nora tells Kitty that she found out about William's affair fifteen years earlier; she caught him in a lie, and he confessed but said it was over already, only to turn around and buy Holly a house. She goes on that he lied and lied, and Kitty feebly protests that William did love her, but Nora bites out that he didn't give up anything to do it. She adds that when she saw the deed, she knew it had never ended (this seems like some license, because "house in Silver Lake" doesn't immediately translate to "affair," but I can believe that it got her suspicions going) and she wanted Holly to feel as small and stupid as she did. Mission accomplished, and I don't throw that phrase around as lightly as some people do. Nora says she's ashamed of herself, but that it felt good. She then completes the secret-symmetry as she tells Kitty she has to tell Jonathan she slept with Warren. Kitty: "Who told you?" Hee.
Back at home, Sarah's having a teary moment in the kitchen when Joe enters and asks if she's okay. She tells him that when he looks at her, she hopes he sees someone more like her mother than her father. Perhaps pleased by her show of vulnerability, he tells her that he doesn't see either -- he sees the woman he loves. She can't help but like this even as she tells him she's a mess, and he puts his arms around her from behind and they share some happy banter. It's a much-needed nice moment for the two of them, because it's easy to wonder later on how they ever liked each other at all, so I'm going to forgive the fact that the end of the scene comes uncomfortably close to suggesting that they end up doing it right on the center island there.
