House

House arrives at the clinic as they decorate for Christmas… and finds Tritter and Wilson waiting for him. Wilson tells House that he confessed he didn't write the prescriptions and they worked out a deal: two months in a rehab clinic in return for dropping the charges. House refuses the deal but Tritter gives him three days.

After Tritter leaves, House goes to Cuddy for pills but she's meeting with a mother-and-daughter who both have dwarfism, and the daughter Abigail's lung has collapsed. House is intrigued by the case and runs a diagnosis, but the mother Maddy is unimpressed by House's sarcasm toward her… which impresses him. Cuddy confronts Wilson who isn't thrilled with him ratting out his friend and notes House won't take the deal. Wilson thinks House will have no choice.

House is running a differential diagnosis and believes it's liver related, when Cuddy takes House off the case and cuts off his Vicodin. The staff runs a MRI on Abigail while discussing House's problems, and confirm that her liver is failing as she vomits blood. Wilson suggests liver cancer but Cameron thinks she's too young. Afterward Wilson confronts Cameron over her hostility and Cameron asks it wasn't an easy choice. She points out that his motives weren't pure, giving him something to consider.

Foreman comes into Cuddy's office to find House working on her desk. He wants to know what House saw and gives him a test, but House refuses to get involved… until House offers him one diagnosis for Foreman opening one drawer. Foreman agrees and House notes the problem is global and it will hit her pancreas next. Unfortunately for House there's no Vicodin in the drawer.

Chase comes back with Abigail's home drugs, including treatment for ear infection, and Cuddy figures out that House gave Foreman the diagnosis, but the pancreas test is negative. House go to another emergency room and claims to have been in a car accident to get some painkillers. It doesn't work.

Foreman and Wilson prepare liver tests but Abigail passes out as her pancreas fails. Cuddy goes to House but neither one will back down. Cuddy goes to the staff and Cameron believes its Lupus while Wilson figures it's cancer. Cuddy orders tests for both but Maddy's is unimpressed and wants to hear from House. Cameron goes to House's apartment where he's clearly in bad shape, and has been cutting himself to release endorphin to relieve the pain. Cameron doesn't have any pills and tells him to take the deal, and he wonders if she's been sick. He wonders if her ear infection is significant and suggests a treatment for Still's Disease, but refuses to yield.

Cameron reports to Cuddy who notes that Still's Disease can't be readily diagnosed, but she orders the treatment. House comes in later to confront Wilson and ask for a drug to stop vomiting. Wilson refuses and leaves, but House spots Abigail's folder and takes a look. He then goes in to interrupt Wilson with Mrs. Zebalusky, the wife of a dead patient to assert his diagnosis was correct. The widow asks him to leave but as he does, Wilson figures out he snagged some painkillers from the dead man's bedside.

Abigail starts to recover and Cuddy notes that neither Wilson or she could have figured it. Later, Wilson meets with Tritter but refuses to testify. Tritter says they'll subpoena him and he'll go to jail with House. While House gets some drugs by claiming to be getting them for Zebalusky, Abigail starts bleeding.

It's back to differential and Wilson suggests leukemia, but Cameron is skeptical and still insists it's auto-immune. Cuddy asks for a half hour. Down in the cafeteria, a much better House is chatting with a little girl and her stuffed dog when Cuddy offers him Vicodin but quickly figures out he got drugs. House figures out that Abigail doesn't suffer from skeletal dwarfism but rather a pituitary problem. And that means House figures she's suffering from both cancer and auto-immune. Gulping down pills, House explains to Maddy and Abigail that Abigail isn't a dwarf and her condition can be treated. Abigail is reluctant to have her height problem treated because right now she's unique. House leaves and Maddy confronts him over it. House points out they're both freaks and Abigail should have a chance at not being a freak. Maddy goes in to tell her daughter to take the treatment and be "normal" no matter what.

Later Wilson visits House in his office and reveals Abigail decided to get the treatment. It's Christmas Eve and the deal runs out the next day. Wilson offers his friend company but House isn't interested. Back at his apartment, House considers the pills and then calls his mom and leaves a message saying "Merry Christmas." He then takes some pills with alcohol. Later Wilson arrives and comes in to find House on the floor vomiting from a combination of the alcohol and the new painkillers.

Later House goes to visit Tritter and takes the deal. Tritter refuses, saying he has new evidence and doesn't need Wilson's testimony. He got hold of the pharmacy logs for Zebalusky and has what he needs. He leaves, wishing House a Merry Christmas.
