So many theories, here's mine. Don't necessarily expect it to happen, but I though it would be a cool scenario. Courtney was tormented by Alison as a child, but the parent's didn't realize it. Eventually, Courtney begins to show signs of DID (split-personality) but her parents don't realize what it is, they just think that she's crazy. They send her to a mental institution. The split personality within Courtney turns out to be Alison, but one even more sociopathic and brutal than the real one. This Alison sneaks out of Radley (or whatever mental institution she's in) to torment original. Eventually, splitpersonality!Alison confronts Alison and tells the original Alison that she was a better Ali than the original ever was or could be, and kills her. Split-personality!Alison then directs her hatred towards Alison's friends. However, Courtney doesn't want to hurt them, so whenever she can get control of the body, she tries to help out the liars (cue hallucinations). Split-personality!Alison is able to get other's to join her by using their hatred for Alison and those that stood by her
