Alison. Alison has a mentally ill twin sister Courtney. Courtney switched places with Alison and it was actually Courtney who the liar's met and who was murdered. Alison hates the liars for becoming friends with Courtney and believing Courtney was Alison. Mona was -A but she was acting on behalf of Alison. Once Mona was sent to the mental hospital, Alison takes over. Or at least that is what happens in the book.
No she is not dead but her twin sister Courtney died so everyone thinks Courtney is Alison. That's in the books, in the show, Alison's alive too, but we don't know how.
The real Alison did but the Alison they knew who was really Alisons twin named Courtney didnt.
Courtney is alison's twin sister, who pretended to be her
Courtney wants to pretend to be Alison meanwhile Courtney was supposed to be in a mental hospital
