Still bearing the scars of her own daughter's battle with schizophrenia, Anya fears for Alex's mental health and attempts to convince him that Ruen doesn't exist. But as she runs out of medical proof for many of Alex's claims, she is faced with a question: does Alex suffer from schizophrenia, or can he really see demons?
