The deer, however, was afraid of the Z, because the Z is a predator. The deer took one look (or listen) of the Z and knew someone (thing) was going to have to be the biotch in this scenario. So she likely ran off to a safe distance to watch the Z make the Prius crawl on the floor with the mail in its mouth like Maggie Gyllenhaal in "the secretary".

Moral of the story: Deer lives. Prius goes home with tail between its legs. Maggie Gyllenhaal goes home with the guy in the Z. Just like Darwin said.
