Fraser makes nightmares about a past attempted murder against Canadian prime minister after Special Agent Helms mocked him about that. It's inspired by a real incident in November 1995 while Aline Chrétien really took an Inuit sculpture to protect her husband.
While going through a security check, Benton Fraser is asked for his mother's maiden name, and he replies, "Pinsent." Gordon Pinsent is the actor who plays the ghost of Fraser's father.
