What Happened At The End?
Vail wants to prove Aaron’s innocence by arguing that he has dissociative identity disorder. To prove this, Vail has Aaron take the stand and then tries to provoke him to get his other personality, Roy, to appear. Vail’s attempts alone don’t work, so he lets prosecutor Janet Venable (Laura Linney) interrogate Aaron.
As expected, her tough approach leads to Aaron bringing out Roy, who attacks Janet in court. This leads to Aaron getting a verdict of not guilty by reason of insanity. He’ll be transferred to a maximum-security mental health facility. Janet points out earlier in the movie that that sentence will likely lead to him only being locked up for a few months.
