Meanwhile, Cuddy adopts a newborn but when the birth mother displays a rash, she has to make a decision between putting the mother or daughter at risk.

Thirteen brings her one-night stand to the hospital after the woman has a seizure. However, the woman admits she slept with Thirteen just so she could get to House and have him diagnose her condition. Meanwhile, House continues to pay Lucas to spy on Wilson.

While en route to his father's funeral, House must help the team with a differential diagnosis on a young Chinese girl who has collapsed under mysterious circumstances.

A painter's undiagnosed illness affects his work, and House and his team must look at the man's paintings to determine what's wrong with him.
