The FAC section on Idgie vs Ninny is nonsense. SPOILERS
"1. Ninny states in the nursing home during her first scene that she was practically adopted by the Threadgoode family, not born directly into it."
In what way does this prevent them from being the same person? Ninny couldn't have LIED?
"2. Ninny Threadgoode also states that she married Cleo Threadgoode, another one of Idgie's brothers. However, Cleo Threadgoode never appears by name in the film, and neither does Ninny, so the confusion is understandable."
Not only "understandable" but INEVITABLE! The reason we never see Ninny or Cleo is that they don't EXIST!
"3. During the wedding scene near the beginning, a child-aged Idgie is on her brother Buddy's back while Ninny says in voice over that she had always had a crush on Buddy. If she and Idgie were the same person, then she would have stated that she had a crush on her brother."
What? Incestuous feelings don't exist? But even THAT isn't nessicary. It might be how Idgie thinks an "adopted sister" would inevitably feel. Thus the "crush is just part of the cover story.
"4. Towards the end of the movie Ninny says that she was told by Sipsey the maid the full truth of Frank Bennett's death. If Ninny and Idgie are the same person, then that statement would have been nonsensical, as Idgie knew about Frank Bennett's death long before Sipsey told Ninny."
Once again it's just part of the cover story as to how Ninny knows about Frank's death.
The implication that Ninny and Idgie are the same person, therefore, is impossible based on several other" NO NO NO !!!!!!
This FAQ is WHACK! It offers NO evidence that Ninny is not Idgie, but instead provides the most impressive reason why they ARE! The fact that there are no Ninny or Cleo in the stories Ninny tellsis very revealing. What old lady (or ANY of us) could possibly tell a long, LONG, story of events they witnessed w/o including themselves??
