A CLUE THAT THEY ARE FOLLOWING TWIN STORYLINE (Spoilers)
I know they said the show isn't the same as the books but.. in the beginning of the special halloween episode, alison is telling a story to a kid that hannah is babysitting. The scary story is about 2 blonde little girls who are playing barbies and one of the girls stabs the other one. After she killed her, she went to the asylum. Doesn't it sound just like the twin thing? (except alison doesn't get stabbed) anyone else find this interesting?
Also if you look at the little who is playing with the barbies they are brunettes not blonde that could be a clue there too.
Lo - lets just agree it was brunette? hahah
