Again the ending...MAJOR SPOILER!!!
SPOILER BELOW!!!!!
If Hyde put the poison in the antidote, and Dr. Jekyll died, as we all saw, how did Mary set it up so that it was Hyde's body on the operating table at dawn? When he died and she lay down next to him, it was Dr. Jekyll. I assume this has something to do with her wanting to protect Dr. Jekyll's reputation, but if he "didn't care what the world thought of him", why was it Hyde who would be found? Thanks!
