Chase is back. His first patient is a cute nun about to make her final vow. While still blaming House, he needs his help with his patient. House and Taub try to one-up each other with pranks.
Chase takes on a patient, Moira, who is a cloistered nun on the verge of making her life-changing vows, and through the treatment process, he and Moira form a unique connection that tests their faith and reason. But when Moira's condition worsens and requires a risky surgery, Chase's judgment is compromised. Meanwhile, House and Taub try to remain one step ahead of each other's pranks.
- Chase (Jesse Spencer) is in bed with a one-night stand who tells him he's bleeding through his bandage. He's been ignoring House's calls. House (Hugh Laurie) shows up at his door and starts talking about a case. Chase hasn't spoken to him in three weeks and still hasn't accepted his apology. When House says he's still Chase's boss and demands he come into work again, Chase challenges House to fire him.
Foreman (Omar Epps) drops by Chase's rehab and suggests maybe he should see somebody. Chase assures him he's fine. Even if he doesn't return to House's team, Foreman wants Chase to work in the clinic so he doesn't go crazy.
Chase's first clinic patient is a nun (Julie Mond) with pain in her left shoulder. Chase realizes she hasn't yet taken her vows and asks whether stress could be a symptom. Her order is one that will require almost complete silence. He tells her that he attended seminary for a period of time. Chase finds a lump in her breast wants to admit her.
Wilson (Robert Sean Leonard) tells Chase the mass is a benign fat deposit. House and the team show up. Chase says he doesn't want House's help and tries to leave. House suggests an infection before Chase walks out.
Park (Charlyne Yi) asks Chase if he wants to talk about anything. He says "just knowing you are there is enough."
Chase talks to nun Moira Parker about her past. They talk surfing. He asks why she decided to be a nun. She begins to vomit.
Chase goes back to House, who suggests maybe Moira has cholangitis.
Moira now can't feel her foot.
Chase returns to the team. Before House will help, he makes reference to Taub (Peter Jacobson) taking self-defense classes. House thinks Chase shouldn't be attaching any great significance to an unexpected event. Taub shouldn't be preparing for them. The next guess is vasospasm, offered up by Adams (Odette Annable).
Adams asks Chase how he is acting so normal about what happened. She is seeing a trauma counselor and thinks he should. He gives her the same brush-off he gave Park.
Chase points out to Moira he's never seen her with rosary beads and quizzes her about faith. She admits she hasn't felt the calling yet and needs the silence and contemplation of the order. She says she's "looking for something more."
Taub pretends to be a clinic patient to hide from House and talk to Chase. He thinks Chase should accept House's apology and come back.
Moira is feeling better. Chase prepares to release her. She admits that while working as a nanny, the boy in her care wandered off and was killed. She's never been able to forgive herself. He tells her not to run. She admits it will be hard not touching anybody. He takes her hand. She leaves.
House thinks Chase is "grasping" at intimacy.
We see Chase bored during a date. He returns home alone and finds Moira waiting at his door. She admits she's been running away and takes his hand. They end up in bed together. The next morning, she begins having symptoms that let Chase know the artery to her brain has a clot. He rushes her to the hospital.
Park chokes when starting to work on Moira. Chase rushes her to surgery. Nobody thinks Chase should operate on someone with whom he has a relationship. House gives the go-ahead. Chase takes a risk during the surgery but the gamble pays off.
After surgery, Park admits to Chase she's scared "of everything." He tells her she needs to act like a doctor.
House suggests Moira could have syphilis.
Moira tells Chase that during her operation, she saw the boy who died. It didn't feel like a dream. He held her hand. She thinks it felt as if he forgave her.
Adams tells Foreman about Chase operating on someone he slept with. He pulls Chase off the case. Chase is upset that he's being treated differently than House.
Adams tells Chase she ratted him out because she thinks he needs help.
Moira has symptoms which indicate she's having liver failure. The consensus in the team is she has lymphoma.
Chase tells Moira they'll know in a few hours if she definitely has cancer, but the prognosis is grim. Chase tells her he left the seminary because he slept with the groundkeeper's wife. She thinks he must have done it because he was struggling with whether he belonged there. She begins having trouble talking, citing pain in her jaw.
This new symptom tells House she must have giant cell aerteritis. She is going to be okay.
Moira is ready to leave the hospital. She tells a stunned Chase she's planning to go back and become a nun. The image of the boy was her calling. Chase says he thinks he's in love with her.
House finds Chase printing off an article that explains what happens to people during near-death experiences. This starts an argument where House tells him he shouldn't be interfering with her decision. Chase thinks this is because House wants everyone to be like him. House tells him if he really wanted that, he'd be urging him to make a terrible decision.
Chase walks towards Moira's room with the article. He stops when he sees her with the rosary beads. He goes in and hugs her.
