Her twin sister was actually "Ali" so Ali actually killed Courtney.
Ali wanted revenge after her sister took over her life and she believed the pretty little liars helped her do so....she wants revenge.
Because she's so hateful.
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.
Ali killed Ali!
Ali kills Ali
because she thot she deserved to be ali and ali didnt. to keep down her parents suspicions that she wasnt ali, but really courtney. so ali would stay at the mental hospital.
what do you think
No Ali is not being Jenna in pretty little liars.
So , What happened was Ali has a twin sister named Courtney that nobody knew about , and she always like to impersonate Ali . Courtney was mental so her parents tried to send her to a mental hospital , But instead they sent Ali . So , Ali came back seeking revenge and killed Courtney , So it really isn't Ali That's dead ! SO ....i guess you could say Ali killed "Ali"!
Courtney took Ali's ring and fooled parents and they believed her so they sent Ali to the mental place and Courtney became Ali Ali became courtney
NO
