I can't believe I never thought of this. Alison might not have a twin sister, but Aria HAS A TWIN. THINK ABOUT IT. Aria is GREAT at lying, right? So, it would be easy for her to lie about her family only including herself, Mike, Ella, and Byron. When they were younger, Aria's twin could have convinced Aria to impersonate her to humiliate Aria, just like how in the books Alison convinced Courtney to impersonate her. Aria's twin could have been angry that Aria became popular and knew it was because of Alison. So Aria's twin killed Alison.

I don't think Aria's twin is Big "A". But there could be reason to it. Aria's twin knew that all 4 Liars together are unstoppable because they have each other's backs and would find out who killed Alison. Even if one of the Liars weren't involved in the mystery, it would throw them off. So, before the pilot, Mona was on the A-Team with Aria's twin. Mona's excuse for being "A" was the rest of the Liars taking Hanna away from her. In actuality, there were two reasons she joined the A-Team. At first, she joined because she wanted to torture Alison and the Liars for Alison's torment on her. Then, when the Liars all were in Rosewood, Aria's twin wanted them seperated and knew that keeping secrets can tear friends apart. But, the plan backfired and brought them closer together, which Mona was angry that Hanna was taken away from her and thought it was the Liars' fault.

Leave suggestions and what you think about my theory. I know it's far-fetched and crazy, but maybe...just maybe it's possible.
