I did not see the ending so I really thought he had killed her
until I talked with a friend of mine later. It was confusing because I read a few weeks ago that Minnie was attacked by coyotes and Ozzy saved her. I wasn't sure how that could have happened if she was already dead!
I think the last episode was a joke in extremely poor taste, but I don't think the rest of the season was scripted. Imagine if those hidden cameras had been in Jack's room all year. They would have made for some very interesting viewing!
