Willis Peyton

Willis Peyton is a guest character in Season 13, Episode 7 (“Jigsaw”) of ER, played by Shawn Hatosy. He initially appears to be a difficult, aggressive patient with flu-like symptoms, but the episode reveals that he has dissociative identity disorder (DID) associated with severe childhood abuse.

Personality

Willis himself

Guarded and distrustful: He has a strong instinct not to trust medical professionals or people trying to help him. Defensive: He can become hostile very quickly when he feels threatened or controlled. Frightened beneath the anger: His aggression is largely a protective response; underneath it is someone deeply traumatized and vulnerable. Independent and resistant: He strongly resists treatment and doesn't like being told what to do. Confused and fragmented: His different identities have different behaviors and emotional states, making him appear inconsistent. Vulnerable/childlike: His more childlike state, Andre, reveals the frightened, dependent side of him that exists beneath his defensive adult persona. Not simply “violent”: The episode establishes that his difficult behavior is connected to his traumatic history. His alter Clyde is particularly aggressive, while Willis is more aware of what is happening. Appearance

Willis is played by Shawn Hatosy, giving him a distinctly rough, somewhat worn-down appearance. In the episode he has:

Dark brown, short, slightly messy hair Light skin Brown/hazel-looking eyes A lean, wiry build A somewhat gaunt, tired face Noticeable facial stubble A generally scruffy, unpolished appearance Casual, practical clothing rather than anything particularly fashionable

His physical presentation contributes to the impression that he's someone who's had a difficult life. Fan discussions of the episode also specifically note his old tattoos, cigarette burns and evidence of old injuries, details that reinforce his history of trauma.

Overall character impression

Willis has a rough exterior with a deeply vulnerable interior. He initially comes across as intimidating, angry and confrontational, but as the episode progresses, the audience sees that his hostility is intertwined with fear, trauma and a desperate need for safety. His different identities allow the episode to show dramatically different sides of the same person—from aggressive and combative to frightened and childlike.
