Mona began torturing Alison by sending her gifts , threats and soon attacking her while wearing a zombie costume . `` A '' continued to mess with Ali and her mother Jessica DiLaurentis , whom she believed it to be Spencer Hastings . After Alison 's disappearance , `` A '' went away for a year but after the corpse of Bethany Young ( believed to be Alison at the time ) was found , she reemerged . `` A '' began sending the Liars messages about things only Alison knew about them and soon even began messing with their parents . Doctor Anne Sullivan had previously dealt with the person behind the hoodie and when `` A '' trashed her office she immediately recognized the person . She almost exposes her identity to the Liars but `` A '' kidnaps her and went as far as to threaten her son 's life . But the Liars are still close to figuring it out and during the second half of season two they manage to get a hold of `` A 's '' phone . They hatch a plan to catch her with this and it works . They find out that `` A '' had a lair at the Lost woods resort and Spencer and Mona ( `` A 's '' newest victim ) head over there and find a room full of pictures of Alison and the girls along with a sketch of `` A 's '' costume to the ball , The Black Swan . However , Spencer begins to notice other clues and soon realizes `` A '' is right there with her . She turns around to see Mona in a black hoodie , who reveals herself as `` A '' . She kidnaps Spencer and gives her an opportunity to join the `` A '' team but Spencer declines and the two get into a fight , where Mona is pushed off of a cliff . Though Mona survives , she is sent to Radley Sanitarium for medical assistance . While in the psychiatric hospital , Mona takes up a partnership suggested by the then unknown CeCe Drake that starts off the second game . After this , Mona became another henchmen in the `` A '' hierarchy , obeying the orders of CeCe , whom she knew as Red Coat . Mona was kicked off of the A-Team in the season three finale . However , Mona joins the new `` A.D. '' team in Season 7 , after `` A.D. '' sends Wren to kill her and she offers to help instead . She helps them kidnap Spencer and wears a Melissa mask , but ultimately turns on them and brings the Liars to them , as well as a cop . However , this turns out to be a ruse and the `` cop '' is actually Mona 's French boyfriend , who helps her take Mary and Alex ( the two remaining members ) to France to live in her own personal Dollhouse . Mona is the final `` A '' of the series , being the `` winner '' of the game . </P>
