House walks up some metal stairs back to the common room despite Beasley's protests that he's supposed to be outside for yard time. House finds the common room empty except for Catatonic Gabby and another woman who is playing the piano. House kind of flirts with her, asking how she got the piano key ("they gave it to me") and if Catatonic Gabby is German like the piano-playing woman is. He figured out she was German after she said one sentence? Impressive. The woman, Lydia, says Catatonic Gabby is her non-German sister-in-law. Her husband, Gabby's brother, doesn't visit because, as Lydia explains, he doesn't know how to play the piano. House doesn't think a whole lot of Lydia's abilities, either, saying she's "heavy" on the right foot as he takes a seat next to Gabby. Lydia doesn't care how well she plays, just that Gabby's head bobs to the music (I guess ... very slightly if at all. It kind of looks more like wishful thinking on Lydia's part more than anything else), which is the only reaction anyone can get out of her. House holds Gabby's hand, like, way to violate the non-communicative woman's personal space, House. After just a few seconds of touching Gabby's wrist, House is able to break Lydia's heart by telling her that Gabby isn't bobbing her head to the music at all, but involuntarily to her own pulse. Lydia asks House if he's a new doctor on the ward. "Technically, yes," House says. And here come Beasley and the orderlies to take him back to the padded room. If Lydia is surprised to find out that the man she was talking to is a patient just like Gabby, it's her own fault. House's patient bracelet couldn't have been more obvious. On his way out, he asks her to leave the piano unlocked.
