I believe that actually Bethany Young is "A", and that her and Sara Harvey is/was twins.

Sara found out that Bethany escaped Radley that night, so she went to Rosewood to go look for her. She followed her (Bethany) into Alison's backyard. Alison killed Sara (thinking it was Bethany) because she hated Bethany and her family because her mom was cheating on her dad.

Bethany Young found out the same night that Alison killed Sara, and Bethany tried to kill Alison (revenge for killing Sara (but actually Melissa did it because she wasn't dead when she burried, but you get the point)) - and Alisons mom saw it. Mrs D covered for her because Bethany threatened Mrs D that she would tell everybody about the affair. And know that Bethany found out that Alison is still alive, she is now "A" for finishing what she started.

''That's just my theory. - A''
