House tells Cuddy his latest theory, handing her some thiamine pills in a bottle labeled as an antacid, all the better to sneak them into Murphy's body. Shouldn't Cuddy be concerned that her boyfriend is so good at making fake prescription bottle labels? This is his second one in like ten minutes. Cuddy is loath to do anything without talking to her mother first. House doesn't think that will accomplish anything, since Murphy will just deny it. Maybe Cuddy should ask her sister instead, since she seems to know everything that's going on in their mother's life. But Cuddy believes that she and her mother have a relationship where they tell each other the truth as long as they are asked for it directly. "Addicts lie," House says knowingly.
Cuddy, pills in hand, tries to kick her sister out of her mother's room to speak to her one-on-one. But Sis won't leave, so Cuddy plows on ahead and says she thinks Murphy's drinking is the cause of her heart problems. "Is it about the champagne?" Sister Cuddy asks, only to be silenced by a glare from Cuddy. I guess we know who the older sister in that family is. Cuddy says she heard from Murphy's friends Patsy and Anne that Murphy "lost control" at a recent museum luncheon that I am very sad we didn't get to see. Also, how does Murphy even have friends? She's so hateful. I wonder if Patsy and Anne are related to Wilson? Murphy angrily denies being an alcoholic. Cuddy says she believes her, but then hands her a bottle of thiamine pills masquerading as antacid.
When House goes to check on Cuddy, she asks him to just proceed with any and all of his wacky theories and treatments without consulting her, because she's too emotionally invested to make the right decisions. "Congratulations. You were right, as usual," she says, all pissed off at House for trying to give her good advice. She's so upset about everything that she doesn't seem to realize that she just basically gave House permission to hang her mother from the balcony by the ankles and call it a diagnostic tool.
