House is an American TV medical procedural drama. “Love Hurts”, aired May 10, 2005, is the twentieth episode of the first season.
The episode begins with a man in the Emergency Room with what appears to be a stroke. The patient, Harvey (John Cho), also has nominal aphasia (difficulty naming things), as his friend Annette (Christina Cox) explains.
As Harvey has a metal plate in his jaw from an earlier injury, the doctors can’t do an MRI scan, and have to diagnose with other methods. They also notice oddities like how Harvey enjoys having needles inserted, and how Annette hovers around the patient. Finally, they find Annette in Harvey’s hospital room, apparently strangling him.
One of the doctors, Chase, explains that she is a dominatrix.
