The real Ali discovered it.
Alison is A because Alison didn't really die-not exactly. Her twin sister did, Courtney. Courtney is a mental patient but she escaped and got her parents thinking that she was Alison. Alison escapes the hospital and kills Courtney.
The real Alison did but the Alison they knew who was really Alisons twin named Courtney didnt.
Alison is spying in the window. Who Hannah, Aria, Spencer, and Emily think is Alison is really Courtney, Alison's twin sister pretending to be her because Courtney has a mental problem.
They saw alison who everyone thought was Courtney.
well, Alison wasnt really killed. It was her twin sister. Her sister, Courtney locked alison in a house and pretended to be alison. alison finally escaped and killed her sister, Courtney. mona was originally and she died, then alison became A.
Well, honestly when I found out that Alison wasn't really Alison and was her twin Courtney who was pretending to be her and had befriended Aria, Emily, Spencer, and Hanna
yes,i've read all the books and yes she does she is mentally ill and convinces people that SHE is alison
she never died she killed her twin courtny and reamber the episode on the tv show where she took some pills and was seachering in spencers bag and then the pills were open when she woke upBecause Alison has a mentally ill twin sister named Courtney. Courtney and Alison switched places, it was really Courtney who died, not Alison.Alison is still alive. And Alison has it out for the liars because they befriend Courtney believing she was Alison.
Yes, Ali and Ian did dating pretty little liar the books and the TV show. You find out that Ali and Ian are dating in flawless. Ali is really Courtney. So Courtney and Ian are really dating, not Ali and Ian.
After Alison (Really it's Courtney) has that fight with Spencer outside the barn where Spencer hits Courtney, Courtney runs and Spencer just remembers seeing her arguing with someone blond. That's because it's Courtney fighting with Alison. Alison and Courtney fight and it's not specified how she actually killed Courtney but she throws Courtney in the hole behind the barn, the one the next day the workers fill so no one realizes Courtney is in it... After that, Alison and Courney's parents take Alison away thinking she's Courtney... she doesn't come back till the last book and nobody knows she's the real Alison...
Because Mr. DiLaurentis and Mrs. DiLaurentis think Alison is dead (she really isn't, Courtney is) she is thought to be Courtney. So, they send her back to the mental hospital until she is revealed in Wanted, the last book in the series. Courtney is Alison's psychotic twin sister who is really dead. Hope that helps! :)
