Cosi

An aspiring director and drama teacher who arrives at the hospital to mount a variety show for the inmates. He must navigate Roy's volatile energy while trying to keep auditions fair and productive. His creativity and patience are tested as he attempts to unite a diverse group into a coherent performance.

Manic-depressive inmate who dominates auditions and asserts control over the cast. His volatile temper and flamboyant demands push Lewis and the other patients to test boundaries. Roy's charisma keeps the group off balance, shaping the show's direction even as his own grip slips.

A suicidal woman who delivers a dejected rendition of 'I’m So Excited', revealing her vulnerability. She is emotionally fragile but also capable of insight and performance. Her presence exposes the fragile lines between despair and expression within the hospital.

A woman prone to making false claims of sexual harassment who lusts after Lewis; she creates tension and manipulates others. She is provocative and self-serving, complicating the auditions. Her behavior raises questions about truth and agency among the inmates.

A recovering drug addict, the only one who can actually sing; she emerges as a bright talent and perhaps a hope for the group.

A cat-burning pyromaniac; dangerous; his presence adds tension; he is unpredictable.

An inmate who is completely submissive to Roy; passive; integrated with Roy's plan; tension.

An accordion player who aspires to perform Ride of the Valkyries wearing a horned Viking helmet; quirky, ambitious; adds comedic energy.
