well i think bc alison blamed the liars for ruining her life and swore revenge
Because the "real" Ali wants revenge on the girls for ruining her perfect life.
You can, but you wouldn't want to.
The motovation is that the girls want to find out who killed Ali.
Wilden and Jason never tried to plot to kill ali, A just made it seem that way but, really wilden and Jason are the good guys. They just seem to be the bad guys who want to kill ali but, there reallly trying to save her.
The real Ali! The real Ali killed her twin sister Courtney who had a mental problem and always thought she was Ali. Ali found out all the girls secrets and is now the new a after Mona vanderwaal fell of the quarry trying to kill Spencer.
because ali made fun of mona, and then when ali was stilll alive . all the pretty little liarss did he same thing to ,mona befor ali died !
the ali that the girls knew was really courtney alis twin sister wich explains why she suddenly became friends with them. the real ali ends up killing the ali that the girls were friends with so the body in the hole is courtney. but in the very end when the real ali comes back she tries to kill the girls in a fire but after the fire she may have excaped but its very unlikely so to answer ur question the girl that the characters are friends with died
Because her sister, Courtney, ruined her life. Courtney pretended to be Ali so who the girls thought was Ali the whole time they were friends was really Courtney. Because they were twins their parents thought Ali was Courtney and sent Ali to the mental hospital instead of Courtney. Ali escaped and killed her sister for revenge.
In the show, Ali does know the girls.
shes married to the guy her sister was last dating
Ali, if it were real. ali will kill him x( lolz but ali wold win )x
First, Melissa and Ian did not kill Ali. If you want to know who killed Ali, and who A is, please read the long answer below! :)*********&&&SERIOUS SPOLIER DO NOT READ IF YOU DON'T WANT TO KNOW WHO "A" IS&&&*********A is Alison. Alison has a twin sister named Courtney who had mental problems and went to a hospital for that. One day when Courtney arrived home for a few hours, she started to act as Ali, and when Ali tried to tell her mom that she was the real Ali, her mom just thought she was Courtney and lying and she brought her to the mental hospital.So, the day that Aria, Spencer, Emily, Hanna, and "Alison" had the sleepover, Courtney had gone into the woods and Ali killed her. She murdered her because she took her life away from her.If you read the books, when Ali was living as Ali, she was friends with completely different people and still popular, pretty Ali. I think they mentioned it in the show, but the girls always wondered why she suddenly dropped Naomi and Riley (her friends before) and went to them. It is all explained in Wanted. :DRead more: Who_is_A_in_pretty_litte_liars_book_series
