::I guess trivia would be the most apt description for it, since it relates to an apparently non-existent role/character development, its just there.  Its not like say, some unreleased concept info that says "She was originally going to be revealed as Jigsaws final apprentice".  Its just saying "They thought of an idea and didn't go with it" but Im sure this could be said of almost every living character that appears in the series, they all tend to get drawn into future films.
