Dont think so because Ali's twin is 'A'
Nope at first i did not know she had a twin but it is courtny dilaurentis
about book ali has a twin sister. her sister is a special ed and she is over at alis house the night "ali" goes missing... but it is not ali that goes missing it her twin. ali gose home after the fight then the twin leaves and gets killed ali doesn't know that her twin left and her parents walk in and think its the twin... but since the twin is mentaly challenged they think when ali is saying shes ali that she is joking then ali tells mona everything about the 4 girls and thinks its funny to mess with them.
There really is no sibling problem between Ali and Jason, it is between Ali and her super secret twin sister Courtney! Its really hard to explain sooo ....................... READ THE 7TH BOOK!
Yes, Ali had a twin.
Because Ali twin is a good after
a is not Jenna Mona was a at the beginning... then Ali was a... because a is not really dead it is her twin sister!
No because she switched places with her twin Courtney so they think that Ali is dead.
She didn't . She killed her twin sister Courtney who was in a mental hospital . One day Courtney switched with Ali and Ali was in the mental hospital . The pretty little liars didn't know Ali had a twin . So Courtney was acting like Ali the whole time . Courtney figured out all the pretty little liar secrets . And wrote them in her diary . Ali was jealous and escaped from the hospital and killed Courtney . Ali has been hiding in Jason's house the whole time .
In the books, Jason DiLaurentis does know. He is closest to Courtney out of the twins
evey thing is ok right now but not really he will know though
No "Alison's" killer is Alison No, the "Alison" that Aria, Spencer, Emily, and Hanna know is actually Ali's twin sister Courtney, who has a history of impersonating Alison. And actually the real Alison kills Ian for finding out the truth about happend.
no Ean is not "A" first Mona is then she gets killed then the real Ali takes over being "A" Ali has a twin sister who is Cortney, she the "Ali" that dies the real Ali kills her, the girls didn't know Ali had a twin and Mona is "A" because she was mad that Hannah started being best friends with the girls. that's all i know for now hope that's helped.
