Pris/raccoon?
I have always thought of Pris as a Cat, and numerous things steer me in that direction. Hear me out:
Just before entering the Bradbury with J.F., she squints her eyes as you hear the howl of a cat, and the streetlights above her head resemble slanted green cat's eyes (intentional & fantastic camerawork BTW).
Also, wasn't there supposed to be an animoid cat outside J.F.'s lapping-up some oil originally? (early script or something. can't remember.)
When she attacks Deck and jumps on his shoulders, it causes her hair to stand on end... like a pissed-off cat.
After her death we still hear the cat's howl during the Roy/Deck chase but, I believe that to be the canine's/Roy's grief as he is thinking about avenging the death of his feline friend.
I may be forgetting some other stuff. Heck, even many domestic cats have masks or spots on their eyes.
I thought about having a poll but it's not such an important issue... just something that always kinda bugged me. I'd rather just hear your thoughts and opinions on this. Anyone?
