My New Theory About A

My New Theory About A 

Just a thought I was thinking about the whole Paul Var Jack alliance and it occurred to me that maybe A is Alison's twin. I know the show says she has no twin but what if they're just saying that to throw us of A's trail. My new theory is that Courtney is a boys name not a girls name he hit Alison over the head with the rock and that is why Mrs. D covered it up she was protecting him. Mrs Hasting found out the secret while going through Alison file that is why she told her to cancel her flight home. Mrs D was killed by A because well she knew too much and I am convinced he kidnapped Mona can't wait to see if I am right.
