"Game Over, Charles" is the tenth episode of the sixth season of the ABC Family mystery drama television series Pretty Little Liars, serving as the mid-season finale.

[1] In the episode, Alison, Aria, Emily, Hanna, Spencer and Mona finally uncover the true identity of "A," who turns out to be CeCe Drake, and they learn why she has been tormenting them.

At the prom, Aria (Lucy Hale), Emily (Shay Mitchell), Hanna (Ashley Benson), Spencer (Troian Bellisario) and Sara Harvey (Dre Davis) meet Mona (Janel Parrish), who reveals that she has been following Alison (Sasha Pieterse) all night to protect her.

There, Spencer breaks into a restricted room after Sara remembers a specific date meaningful to Charles, which is the code for unlocking the door.

As the girls witness Alison discovering Jason and Mr. DiLaurentis's unconscious bodies, they realize she's alone with "A," who is revealed to be CeCe Drake (Vanessa Ray).

According to CeCe, as a child she asked her mother to purchase her dresses, but Kenneth despised his son for being feminine, so he used the bathtub incident as an excuse to send him away.

After the funeral at Aunt Carol's, Jessica finally accepted Charles as her daughter and took her back to Radley, renamed Charlotte.

She used the opportunity to go to Rosewood High for yearbook picture day, where she met Jason, whom she began dating under the CeCe Drake alias in order to get closer to her family.

On Labor Day Weekend, Bethany stole Charlotte's clothes and snuck out of Radley to murder Jessica at the DiLaurentis property.

Back at the Carissimi Group, Mona tearfully admits that she hit Bethany that night and mistook her for Alison, since they both had blonde hair and were wearing the same clothes.

After Charlotte was released from Radley, she moved to Rosewood, where she purposely met the Liars, and began hating the girls due to their relief over Alison's disappearance.

She killed Wilden to protect Alison, since he would've never allowed her to return to Rosewood, and sent Sara to his funeral, costumed as the Black Widow, to ensure he was deceased.

Before Charlotte fled to New York, she snuck home to say goodbye to her mother, only to find her lifeless body lying in the DiLaurentises' backyard.

Following her mother's passing, she saw the events in New York as the perfect opportunity to end the "A" game and begin a new life in Paris, but eventually came back, due to her addiction to power.

Sara, dressed as Red Coat, sets a bomb to detonate inside Radley as part of Charlotte's final plan to kill her family and herself.

On Labor Day weekend, the five Liars stand outside Alison's house, with their cars all packed and ready to leave for college.

As a regard to who 'A' is going to be, King said "We knew that Mona was the original "A," but we didn't know how long we were going to be able to go to sustain that story before we gave her up to the audience.

- I. Marlene King to BuzzFeedJoseph Dougherty, executive producer, expressed his concern over the amount of material the writers had to deal with in the first half of the sixth season in order to reveal who 'A' is when crafting the first ten episodes.

"[12] King revealed in an interview with The Hollywood Reporter that "lots of people" have correctly guessed A's identity", but noted that fans would still be shocked to learn A's motives for living a life devoted to stalking.

"[14] Troian Bellisario said in an interview that "it was thrilling to watch this mysterious actor "really stretch their legs" as 'A' in Tuesday's summer finale.

The episode deeply divided fans, since some viewers expressed considerable dissatisfaction in regards to CeCe Drake's motives for becoming the show's primary antagonist as well as Sara Harvey's reveal as the third Red Coat and Black Widow.

Although he described it as "an episode that fulfilled its promises," finding that CeCe as A was "a solution that fits" and Sara Harvey as Red Coat "added up beautifully," Campbell noted that it was "a flashback to cornier times."

Ferguson applauded Vanessa Ray's emotional performance "reminding the audience (and characters) why they were drawn to CeCe in the first place".

[18] Writing for The Washington Post, Bethonie Butler agreed that the identity of A made more sense than Gossip Girl's reveal, although it was, in her opinion, obvious and disappointing.

Further, with regards to the flash-forward, Butler wrote: "it’s kind of odd to spend all that time in high school, only to breeze through college and land abruptly into adulthood.

[21] Entertainment Weekly's Isabella Biedenharn deemed the reveal "satisfying", saying she did not understand people's disappointment and that Wren or one of the Liars "would have made no sense".
