He returns to Mayfield after hours, and yet, there's Lydia in the common room, crying. Crying because she's locked in because the staff apparently forgot she was there and now visiting hours are over? Crying because Franka Potente heard such good things about this show but is appearing in an episode like this? House assumes she's crying over him. He says he pushed her away and he tends to do that to people because he's afraid. Hooray. House is in touch with his feelings now. Lydia says she isn't crying over House, but herself. That makes sense. Lydia is nothing if not self-centered. She says she brought Gabby's cello to the hospital in the hopes that she'd snap out of her decade-long catatonia and play in the talent show. Well, she didn't, and now Lydia thinks she's "pathetic." House says everyone is, and that's what makes life interesting. Lydia says she's sick of things being interesting. Then stop visiting your friend every day in the mental hospital. At what point does it stop being a supportive gesture for a friend and start being self-flagellation? Or, apparently, a way to meet hot boys.
House offers Lydia a hand. She takes it and stands up and they hug. House hangs up his cane so he can have both arms free to hug her back. They start swaying to the music that isn't there. And then they find an empty room (that House somehow has to keys to. Okay ... ) and have sex on a chair while mostly-clothed. House cries at the end. Maybe it's because he knows he has terrible taste in women. A woman who would cheat on her husband with a current mental hospital patient? Not a prize.
