In response to question 12: First, I want to note that we have seen the A.D. initials at least twice before: 2x24 when Alison and A were communicating through newspaper ads and 4x22 when Emily mails Alison money using A.D. Incorporated. In 6x20, A.D. thinks they have discovered Charlotte's killer, so they can now "reveal" themselves. This sets them up perfectly to manipulate the girls to finish the game (as I mentioned in my earlier post). Plus, using A.D. after striking is a bigger mind game.
Yes, but in both those instances, I believe AD stood for Alison DiLaurentis as opposed to Alex Drake (for example, Twincer). I think those were coincidences that the letters A and D have appeared.
That’s very true, never thought about it like that.
