This is about the scene in Donnie Darko where Karen (English teacher) and Monnitoff (Science teacher) have this conversation:
Monnitoff: Donnie Darko.
Karen: I know.
Both of them laugh afterwards.
The scene seems out of place to me. What exactly about Donnie Darko are they talking about? Does this have anything to do with the film's science fiction concepts (the Living Receiver, the Manipulated Living, etc)? Or is it about something more mundane? What is the scene or dialog's significance to the plot of the film?
