I find it very interesting about the movie and book. Maybe in his own way, he's trying to "enlighten" you and your daughter about what is going on w/him. Some of them do give family members movies, books, poems and songs to listen to that describe what they are going through.
I think, in his own way, he's trying to tell you he's not ready to sign the papers. I do not believe there is anything you have to be concerned about something more troubling. I just think he's trying to delay the process because he's not ready to totally walk away.
Just my two cents.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
