OK this is going to sound weird... But I am watching a movie by Taka****
Miike called "Ichi The Killer".
Spoilers.
A bit into the movie, and Ichi who is exacting revenge, is receiving
"Orders" for hits on people that were like the bullies in his younger
days.
Ichi was his Picture man, Ichi chose his victims.
Something tells me that it's all in his head. So what if the Polaroid guy
was Frank himself? The last episode where he and Jordan are running
away, Frank was running away fron himself?
