In the fourth season's mid-season finale "
Now You See Me, Now You Don't", the Liars head to Ravenswood to look for Red Coat. While there, Red Coat kidnaps Emily and locks her in a coffin on a Sawmill. The Liars witness Red Coat heading to that Sawmill and chase her inside, where she actually stops the saw and another Red Coat, donning a mask of Alison's face, appears on the stairwell, revealing that two people have been sporting the disguise all along. Spencer follows the Red Coat who saved Emily, while Aria fights the masked Red Coat and unmasks her as
CeCe Drake. The Liars manage to catch the Red Coat who saved Emily in the ending of "
Grave New World", who reveals herself as an alive Alison. During "
Escape from New York", Aria claims that she asked CeCe to wear the disguise to distract "A" and that CeCe was never truly Red Coat. It is later revealed that CeCe actually was the Red Coat who stole the game from Mona and wore the disguise during her schemes, presumably until the saw mill incident. In "
Game Over, Charles", the Liars learn there was a third Red Coat who posed as a decoy for CeCe and used the infamous disguise to distract the Liars whenever CeCe couldn't. The third Red Coat is revealed to be
Sara Harvey. ===Exegesis: summary of episode "
Game Over, Charles"=== Big "A" kidnaps Alison from the Rosewood High senior prom and takes her to Radley, where their dad and brother are also there, unconscious. With Mona's aid, the Liars figure out that "A's" phone server is located at the Carissimi Group's building and along with Sara make their way over there. They manage to break into a secret room hidden in the wall of an empty storage room. The Liars and Mona go inside but Sara suspiciously leaves them behind, just as the door closes. A holographic monitor comes on and the Liars get a glimpse of a live feed that shows Alison in a room, talking to "A". "A" turns around and is revealed to be CeCe Drake, who reveals that she was born as
Charles before transitioning into Charlotte. CeCe/Charlotte reveals that she became "A" (and thus Red Coat) in order to sneak out of Radley and because she was angry that she thought the Liars were happy about her disappearance. While Charlotte is telling her story, the Liars are alerted to a motion sensor in another room. Mona turns the camera to the room and they see that the motion sensor was alerted by Red Coat, who is setting up a bomb for Charlotte to blow up Radley with her family alongside herself. The Liars are stunned by this revelation, having previously assumed that CeCe and Alison were the only two Red Coats. Charlotte mentions that she kept seeing a blonde girl in a black coat watching the girls and deduced the mysterious entity was Alison. So in order to find out, Charlotte organized the lodge party at Thornhill to trap the girls and lure Alison out of hiding, since she knew her sister would only show up if her friends were in grave danger. Charlotte sent the other Red Coat to the Lodge to distract the Liars and keep Mona occupied. She reveals that the other Red Coat is Sara Harvey, explaining that she was a decoy whenever she "needed her to be". Nigel Wright was paid to fake a flight plan to Delaware by Charlotte but the plane actually made its way to the lodge since Sara landed it in a nearby field despite the fog in the area.
Shana Fring also showed up with
Jenna Marshall to find out if the Liars were going to meet Alison at the request of
Melissa Hastings, since she too had her own suspicions. However, both plans went away and while Jenna wasn't noticing, Shana set fire to the lodge since she grew a hatred towards the Liars for blinding Jenna as she later admits to in "
Escape from New York". Sara managed to rescue Aria, Emily and Mona while Alison arrived just in time to save Hanna, giving Charlotte the much needed confirmation that her sister was indeed alive. Knowing that Wilden would never let Alison return and tell her story, Charlotte went to the lake and killed him, dumping his car and body in the middle of town. She then sent Sara dressed as the mysterious woman in a black veil to attend his funeral and ensure he was deceased. The Liars are shocked about this revelation, but Hanna tells Emily that Charlotte is just messing with her. However, Spencer realizes that the authorities haven't arrived to Radley because Sara must've pretended to dial them. The Liars manage to break out of the room and head over to Radley, where they come upon Sara in the hallway. She orders them to leave as she turns on the bomb for Charlotte, but they manage to subdue her and give Spencer enough time to stop the bomb. Alison quickly arrives and tells them that Charlotte has headed to the roof and begs them to help her surrender. Sara tries to escape but Emily grabs her by the hood of her trench coat and angrily punches her in the face for betraying her trust. They chase Charlotte and persuade her not to commit suicide. She instead declares an end to the "A" game. At the end of the episode, Emily mentions that Sara is getting released from the local town's hospital and Alison states that what happened to her that night wasn't their fault. Nonetheless, Spencer discloses to Caleb during "
The Gloves Are On" that after Emily punched Sara, she got back up but accidentally put her hand on some electrical cords, which began electrocuting her body, as the Liars watched in horror. This led to Sara being unable to use her hands since she lost her palpable abilities. ==Reception==
