i remember in the good ol' days when we were compiling theories, one of the minor ones was in regards to what happened to ben's friend annie from the DI. a lot of us thought that annie grew up to be diane (kate's mom).
i think there was even an octogan box at her mom's place on the fireplace or somewhere. (we later learned that it was just one of many set pieces that were recycled on the sets.) a lot people thought this was supposed to be a subtle clue.
i'm thinking about compiling all the false clues/ dispelled theories... i know there's a section like this already, but now that the show is over, i think all of us who've been here since the beginning can definately expand it to something bigger. especially considering that most of the theory pages were cleared not too long ago.
