Chona

"Now you know what it's like to really be afraid. The way you made us feel. Say goodnight to the world, bully."

- Mona to Charlotte in Farewell, My Lovely

Chona is the antagonistic relationship pairing between former A-Team Members and creators, Charlotte DiLaurentis and Mona Vanderwaal.

Relationship
The relationship between Mona and Charlotte was always a negative one, even when they didn't really know each other. Charlotte, as "CeCe Drake", manipulated and fed Alison DiLaurentis ideas on how to bully Mona throughout High School. She even helped Alison name Mona, "Loser Mona". After Alison went missing, Mona started stalking Alison's former friends under the alias of "A". After she was caught and admitted to Radley Sanitarium, she befriended Charlotte (who she originally mistook as Alison) and told her all about the game and the girls. Charlotte made a deal with Mona: Mona would help her get out of Radley, and in return, Charlotte would play the game with her. Charlotte became addicted to the game, and stole it from Mona to become a much more vicious A. Later, Mona attempted to get close to "A" to figure out her identity, and the pair planned a fake murder that would result in Alison being arrested. Mona planned to sabotage the deal by turning on A, but Charlotte found out and viciously attacked her over Thanksgiving break. Charlotte kidnapped her, put her in The Dollhouse, forced her to pretend to be Alison (dress, talk, and act like Alison), and tortured Mona when she didn't do as Charlotte wanted. After Mona escaped and Charlotte was revealed to be A, Mona continued to be haunted by the events and had nightmares for many years. Five-years-later, Mona returned to Rosewood for Charlotte's hearing, and told the judge to let her out and that she sympathized with her. Charlotte was found dead after her release, and months later, Mona confessed to having killed Charlotte in self-defense.
