when do we find out cece killed wilden
Charlotte Drake In "EscApe From New York", CeCe is taken away by officer Barry Maple to be sent to jail, however, at some point she knocks him unconscious, steals his cop car and heads off to New York where Alison and the Liars are. Drake finds Ali and asks for her help since Alison owed CeCe a favor for helping her out in Ravenswood. Alison offers her a plane ticket to France and she leaves the country, under the alias of Vivian Darkbloom. When Emily catches Alison, she divulges that CeCe was being paid by Ezra for information. Ali further claims to have asked her to dress up as Red Coat only to distract "Big A". However, it's revealed much later that, unbeknownst to Alison, CeCe was the person who stole the "A" game from Mona and donned the Red Coat disguise during some of her missions. Ali also reveals that Drake was accountable for Wilden's murder.
