I think that Alison has a twin (Courtney) and in the Halloween flashback when ali was getting texts from A it was actually Courtney. And as it showed in a flashback in season 2 (cant remember what episode) Mona was explaining to spencer that she once saw ali as Vivian darkbloom watching someone from a window, so she could’ve been watching A or Vivian could’ve been Courtney looking at ali?

So I think ali and Courtney had a hateful relationship and was spying on one another, and ali ended up killing Courtney and put her in her place and now ali is tormenting the girls with all the secrets. I also think ali and toby had a thing and that’s why toby is helping A. I also think that when the girls zoomed up on the i.d. card, and found it was Vivian, it could’ve been Courtney’s and that’s why they Mona saw her in the shop watching someone.

But that’s just my theory.
