Who kills Ali in Pretty Little Liars?

Answer 1

n the Conclusion to the Series " Wanted" it is revealed that Ali has a twin named Courtney who did not live with the family due to health problems. Courtney comes to Rosewood day where she befriends the four PLL and tells them that she is really Ali. She explains that Courtney was home the weekend of their sleepover and that after her & Spencer's fight in the barn she went back to her house. However Courtney was out & about and Ali says that she was the one who got murdered by Billy ( the supposed murderer revealed in " Heartless"). Since Ali was supposed to be at the sleepover and Courtney at home the parents believed that Ali was Courtney. Leading them to believe that Ali had been the one murdered. When Ali tried to explain that she was Ali not Courtney her parents refused to beliebe her, since Courtney would always say that she was Ali due to her mental problems. The girls believe that there friend Ali has returned and the story continues. Later on in the book the girls all go to Ali's house in the Pocanos where she convinces them that the best way to forget about the horrible night Courtney went missing was to re-do it. The girls agree and Ali hypnotizes them. They wake up from the trance to find Ali missing and the smell of smoke. The realize the house is on fire and find a note on the floor from "A". The note says as follows

"Once upon a time, there were two beautiful girls named Ali & Courtney- but one of them was crazy. And as you know, with a few magical twists of fate Ali became Courtney for while. But what you don't know is Courtney became Ali too.

You heard me right Pretty Little Losers... and it's all because of you. Remember when you stalked me in my backyard for my time capsule flag? And remember that girl who trotted out to the lawn and talked to you? That wasn't me. As you astutely figured out, Courtney was home switching from the Radley to the Preserve that weekend. And oh, how poor widdle Courtney didn't want to go. She has her neat, crazy little life at the Radley... and she didn't want to start over at a new hospital.

If she had to start over somewhere, it was going to be in Rosewood. And start over she did. She was supposed to go to the Preserve the very morning she saw you sulking around my yard- and man, did she jump on the chance fast. One minute she and I were arguing- I was so happy she was on her way out- and the next she was in the yard, pretending to be me, talking to you guys like you were BFFs. Talking about my flag, as if she hadn't been the one who'd stolen it first and then ruined my masterpiece with that stupid wishing well. How was I supposed to know that everyone- my mom, my dad, even my brother- would think it was me out there and Courtney inside? How was I supposed to know that my mom would grab me in the hall and say it's time to go Courtney? I pleaded with her that I was Ali, but my mom didn't believe me, all because Courtney took my A-is-for-Ali ring when I wasn't looking. My mom yelled outside to the girl who wasn't Ali that we were leaving, and the girl who wasn't Ali turned, smiled and said " Bye!"

Off we went. Courtney got my perfect life, and I got her wrecked one. Just like that.

She ruined everything. She put her lips all over Ian Thomas. She nearly got arrested for blinding prissy Jenna Cavanaugh. She ditched Naomi and Riley, the coolest girls at school. But the very worst thing she did in my name was choose four new best friends in their place. Girls she knew I wouldn't look twice at, girls who weren't special in any way. Girls who she knew would fall all over her, desperate for the opportunity to be in her exclusive club. The girls who'd help her get everything she wanted.

Any of this sound familiar ladies?

But don't worry. This little fairy tale can still have a happy ending for me. I saw to it that my sister paid for what she did. And now, so will you.

I tried to burn you . I tried to make you crazy I tried to have you arrested. I even messed with you this week.-- surprise! I flung myself at Aria's boyfriend. I sent poor Hannah fake tickets to a certain fashion show. I let Em believe there was a happily- ever after for us after all. Smooch! And Spencer.... I have a surprise for you. Look closely! It's right under your nose.

I suppose I should thank Courtney for her meticulous diary keeping. It helped me - and Mona- so much. It's all led up to this big moment. The curtain's about to go up, bitches, and the show is about to begin. Get ready to meet your maker. It won't be long now.

Kisses!

A ( the real one) "
