In the third season, Christian is sexually assaulted by The Carver, a masked serial rapist preying on McNamara/Troy's patients. He is briefly suspected of, and arrested once for, the Carver's crimes. A distraught Christian temporarily withdraws from work, prompting Sean to bring in another surgeon, Quentin Costa (Bruno Campos). Costa involves himself in Christian's relationship with Kimber, and the two become bitter rivals; Campos is eventually revealed as the Carver. Christian almost marries Kimber, but the relationship sours after she is kidnapped by the Carver; after she is rescued, she refuses to let Christian see what the rapist had done to her face and body. She breaks off their relationship so she can recover emotionally from her ordeal. Eventually, Kimber comes back as a Scientologist. When Kimber gets pregnant, Christian steals DNA for a paternity test, convinced he is the father.
