Having returned from Minnesota without Abigail, Will wakes up the next morning and vomits up her ear. Evidence is soon found linking him to the murders of Cassie Boyle, Marissa Schur, and Dr. Sutcliffe, but Will is sure he didn't kill any of them. He escapes and convinces Hannibal to take him to Minnesota, where Will realizes that Hannibal is the killer. Jack shoots Will before Will can kill Hannibal and Will is held, pending trial, in the Baltimore State Hospital for the Criminally Insane.
