In the 7th book, Heartless, it is suggested that Billy Ford killed Ali. In the 8th book of the series, Wanted, the truth is revealed (in somewhat retroactive continuity).Ali secretly had a twin sister, Courtney, who the girls knew as "Ali" until she was killed, actually by her sister the real Ali. Courtney was pretending to be Ali while Ali was in a mental hospital overseas. When Ali came back, she was so mad at Courtney for pretending to be her that she pushed Courtney into a hole, killing her. Aria, Emily, Spencer and Hanna didn't know about Ali's twin, so they were led to believe that the real Ali died.Mona was originally "A" because she was jealous that Hanna dumped her for Aria, Emily, and Spencer. Mona was "A" for awhile until she was killed at Homecoming. After Mona died, Ali took on the "A" persona.It wasnt Ali that died. It was Courtney.Well, in the books, Ali had a twin sister Courtney who switched places with Ali, then Courtney became friends with the 4 girls. Ali was mad at Courtney because of the switch so ali killed Courtney that night. and the REAL Ali was alive and courteny was killed.First of all Ali was really Chelsea, Allisons Twin sister. They switched places because Chelsea wanted a normal life ( was in a crazy house). So to make the long story short, Ali Killed "Ali"Read it in Wanted, The Last Book
Ali (the real Ali) kills Courtney.
No one, she isn't dead. Ali had a twin sister named Courtney, and Courtney wanted to be her. So when Courtney was being transferred to another mental facility, she switched places and Ali's parents sent Ali to the facility by mistake. She tried telling her that she was Alison, but she didn't buy it because Courtney pretends to be Ali. So the Ali that the four girls knew was Courtney. So that night when Spencer gets into a fight with Ali(Courtney) Courtney gets killed. Ali killed Courtney out of revenge for ruining her perfect life. Thus Ali killed Ali.
ali had a twin named courtney who was the real best friend of the four courtney was the one murdered.this happened because alps mom mistakes ali as courtney and courtney as ali and courtney is mental so they sent ali to the preserve as courtney without knowing ti was the real ali so ali was hiding at the preserve.
Ali's mom introduces their daughter who is Courtney (Ali's twin) then Courtney asks them to talk to her...she eventually tells them how Courtney had mental issues and that she always wanted to pretend to be Ali and the night that Ali was supposably killed it was Courtney who was killed and Ali tried to tell her parents that she was Ali but they thought that it was Courtney saying she was Ali again so they sent her to a mental hospital for years and then she came back later
Its was it was a lil if Ali but after Courtney she started to get obssess with him
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
When you say "aali" do you mean Alison DiLaurentis? Well if so, Ali wanted to get back more at her twin sister Courtney for being friends with total "losers". She was mad that these girls were involved in her life. Ali didn't get to live her life all that time because she was mistaken for Courtney and shipped to a mental institution. Ali seeks revenge because she had lost so much. In my eyes, Ali was a mean, bitter, person. If I had to choose I like Courtney more even though they were both equally rude.
Ali isn't dead. The whole time it was Courtney pretending to be Ali. Courtney is sick in the head and somehow managed to switch places with Ali, then Ali came back and killed Courtney :)
The real Ali killed her twin Courtney. Courtney was friends with the Pretty Little Liars. Ali didn't like Courtney.
