Callie admits that her mother didn't really hit her. She just lied because she wanted to get out of seeing her mother and it was a simple story. Her new story is that she had to get a job and work double shift to keep her mom alive. So she decided to leave and be a grown-up on her own. This is exactly like the story that Chase told last week, but even though he's in the room, he doesn't seem to notice. Adams assures her that her mother wants to try again. Callie says that she'll feel that way until she starts using again.

Adams and Chase in the lab. They want to talk about people changing, but first they spot a bleeding ulcer in Callie's esophagus.

House's office. The team throws around lots of diagnoses. Adams suggests alcohol-induced esophagitis, since there was a lot of beer at the house. House says she hasn't been drinking around them. So maybe some of the symptoms are due to the DTs? He suggests a berry aneurysm. There's no sign of that on the CAT scan, but it could have been hiding. The two proposals are alcoholism and berry aneurysm. Let's do some brain surgery!

Taub and Adams tell Callie and she accurately notes that they don't believe the aneurysm theory. She says she's not an alcoholic, since she only has beer with friends occasionally and most of the beer she keeps around is for payment. She insists she's not an addict. She wants the brain surgery. But it's her mom's decision. Callie orders her to approve the surgery. "I need a few minutes," says mom.

House yells at Adams for undermining his diagnosis in front of the patient. She tells him not to bully the mother into approving brain surgery because she's feeling overwhelmed. House says the daughter is going to die from the aneurysm she decided not to treat.

House sits by the mother and ostentatiously takes some Vicodin in front of her. He tells her she shouldn't be making the decision. He wants her to leave. He follows up, "She hates you" with, "Your daughter is better off without you. So let her be better off without you." He tells her he's doing the surgery. And he seems to have left his pill bottle next to her. She reaches down slowly and eventually calls after him. "My daughter's care is my choice. And so is this. Treat her for alcoholism." She gives him the bottle back.

Foreman asks Chase and Taub why Anita would tell her husband about the affair but not stop. Yeah, why? Chase is playing with the kids and getting on Taub's nerves. Foreman mopes about hurting the husband. Moving on.
