Why is Alison texting in Pretty Little Liars?

Answer 1

Mona is sending the messages but how does Mona know the girls secrets? Maya left the stuff that was left of Alison outside and Mona toke Alison's diary who carries all the girls secret in and she sends them to the girls to get them freaked out. and then Hanna is hit by a car but before she got hit she found out that Mona was A and during the car crash she lost her memory but then she starts remembering and tells Spencer because Spencer was with Mona and Mona tries to kill Spencer before she reads that text but Spencer lands up killing Mona . but then the new A is the real Alison ( Courtney was the one who was playing Alison while Alison was in the mental hospital) and the real Alison send them the texts

Answer 2

Well, to be honest -A really isn't Alison. A is actually Mona in the books. She knows all of their secrets because she hung out with Hanna once everyone split up. So -A is not Alison. -A is Mona.

Answer 3

A is Alison. Courtney (her twin sister) pretended to be her on the night "Alison" went missing, so it was really Courtney who died. Ali killed Courtney for ruining her 'It Girl' life by befriending the 4 girls. She send text messages to have revenge

Answer 4

Mona was sending the girls texts in Pretty Little Liars because if she didn't, she's would get tortured like the liars are. She was doing it for her protection.
