Question: who is redcoat in pretty little liars?
Answer: Confirmed in "Game Over, Charles", Charlotte DiLaurentis (alias CeCe Drake) was the one who stole the game from Mona and was thus the "evil" Red Coat. She had been caught in the red coat before in "Now You See Me, Now You Don't" , but Ali claimed that she asked Charlotte to wear the coat as a decoy to distract "A".
