Mona is -A in Pretty Little Liars in the beginning of the series. However, she is killed by falling off a cliff. Aria, Hannah, Emily, Spencer, and Courtney (Alison's twin sister) were always mean to Mona and she wanted to get major revenge. In this show, Courtney really dies not Alison. Courtney had problems and that's why she made her "best friends" do stupid things. Alison went away and she is coming back to also get revenge on the girls because Mona was her best friend and the girls had ruined Alison's life.

In the end Ali becomes the real A and is the killer. Alison has a mentally ill twin named Courtney that none of her friends knew about. Courtney escaped from a mentally ill center, pretended to be Ali, and had her sister sent to the center saying Ali was Courtney. Courtney read Alison's diary containing all the girls secrets.
