You guys.. A is Allison. (Allison originally had a twin sister) Evil Alli went to a mental hospital because she was bipolar and tried to kill her twin. So, in the meantime, her twin (Good Alli) became friends with the Liars, and kept a journal of all their adventures. Evil Alli had somehow escaped (I forget whether she was released, or ran back home). Good Alli dies (at the hands of her evil twin), and Evil Alli goes on to set her sights on her twin sister's friends as a sort of 'revenge.'

Basically, the real Alli is alive, and very evil.

Her twin sister was posing as her in her stead, and died, letting evil Alli take back her throne. :-)
