This is a great episode centering around ace musician John Henry Giles. He comes into the hospital with one condition. But House wants to diagnose and fix another condition, one which has already been diagnosed, and is being treated by another famous doctor. And in doing so, he ends up in court, facing a charge of assault.
Dr. James Wilson is the one friend House has. And he knows House better than most people; that Giles is a puzzle and nothing more. And he points out this fact to House in the courtroom.
