Chase's religious faith bubbles to the surface when he treats a young nun. In addition, he and House reach a fundamental disagreement about the patient that may finally end Chase's reputation as House's "yes man" but also bring's House's methods, reputation and objectivity are given more serious scrutiny.

House and the team take on the case of a 22-year-old minor league hockey player who collapsed while coughing up blood after a fight on the ice. Meanwhile, House drops a bomb on Wilson, and Chase offers to help Park change her living arrangement.

Over the years, during the course of performing autopsies at Princeton-Plainsboro, Dr. Peter Treiber has often identified mistakes made by physicians that caused the patient's death. These observations have left him questioning the skills of nearly all the doctors on staff... all, that is, except House. When he falls ill, he demands that only House make medical decisions concerning his care. Unfortunately, House and Wilson have taken off on an impromptu road trip without telling anyone, leaving the team to fend alone and lie to their patient to make him believe that House is the guy calling all the shots.
