MP Creative - Altered Realities: The Beginning

When a contestant comes on the show, the audience will remember how she changed until the show is over. After that, they will remember that the show alters people, but have no recollection of who was the contestant.
The people who already know the contestant will not notice anything different about them. Those who don't know them prior to the show will be seeing the contestant for the first time.
The contestant themselves are given no coping mechanisms (other than clothing or something the show provides) for their changes. They have to work through whatever happened to them.
