Well, the list is short now so it probably wouldn't be a bad idea just so we don't lose track of the remaining contestants on the list. Although I don't mind updating anyways.

Next to go is
Amber from "The Silver Cannonball of Grandy Nanny". I honestly don't remember a thing about her besides backtracking to the Observatory and being slow. Other than that, she was forgettable and doesn't warrant placement on this list anymore. There are worst on this list also.
