After my rewatch, this is what i came up with. There are part I don’t know or I’m not 100% sure, like what character is Charles and how (and if) does Sarah Harvey fit in all the story.



I’m certain Cece is our evil bitch. This theory possibly covers all her life and motives.

P.s. I’m sorry in advance for any possible grammar mistake, English is not my first language

PART 1 - Jessica, Marion, Charles and Bethany

Jessica and Marion are (well, were) twins. Jessica gave birth to Jason and later to Alison, while Marion to CeCe and Toby.



Marion cheated on Mr Cavanaugh and the result has been CeCe. He decided to give CeCe up to adoption because she was not his natural daughter and he said he couldn’t love her.



Mr and Mrs D were considering about adopting a little boy, Charles, who was an orphan and with the same age of Jason.



The families, including Charles, met at the Campbell’s farm and they spent a beautiful day all together. That day, Charles became jealous of Ali because all the attention was towards her, he became violent and broke Ali’s arm. Because of that episode, the DiLaurentis refused to take Charles in their family and the boy has been given in adoption out of Rosewood.



Marion started to work at Radley as a pediatric nurse.

Years later, Marion had several mental breakdowns because she was still missing her first daughter and eventually she ended up being recovered in Radley. Bethany was also recovered there because of her mental problem. Marion met Bethany and saw in her the daughter she never had. While visiting her sister, Jessica met Bethany as well and saw in her the good copy of Ali. Both Marion and Jessica were in love with Bethany, they started to fight to have their bonde doll, exactly as the twins did in Ali’s story in 2x13.

Jessica ended up killing her sister by pushing her down the roof, while Bethany was watching. Mrs D then covered everything with Wilden’s help.

PART 2 - CeCe

CeCe grew up happily with the Drakes, but she menaged to collect informations about her natural family. She was meeting her mum in Radley and she knew how much Marion cared about the girl.

CeCe was the Queen Bee of Rosewood during her high school days and she was Prom Queen in 2007. She then went to UPenn.

During the summer , she met Charles and she fell in love with him. One day, Charles told her about when he broke Ali’s arm and had been refused by his adoptive family. CeCe already knew Jason at school and she became curious towards the little Ali. Anyway, CeCe and Charles spent a beautiful time together, they greeted each other promising they would have see again the next year and they went back to their reality. CeCe was truly in love with Charles and he was the first to deeply love her back.



Back in Rosewood, CeCe met and befriended Ali. They were totally alike and people were confusing them all the time.



Ali was the new Queen of Rosewood. Everyone was fascinated by Ali, including CeCe’s friends. One day during the summer 2008, Ali met Charles and he liked her, even if she ruined his life. Later, CeCe broke up with Charles.

A’s messages started in October 2008. It was Cece. She wanted to scary Ali and to make her change.



In 2009, CeCe got kicked out of UPenn because of Ali and her evil four friends.

It was enough, and CeCe started to be jealous of Ali and to hate her. She wanted to dimostrate to everybody and to Charles how much evil Ali was. So CeCe set Ali up for the Jenna Thing, because she was jealous of Jenna too. Mr Cavanaugh made CeCe up to adoption because she was not his natural daughter, but he welcame Jenna after Marion’s death.

Anyway, Ali blamed Toby for the Jenna Thing.

Meantime, CeCe started to met Bethany in Radley with the name of Alison and she found out how Marion died. CeCe wanted Bethany to hate Mrs DiLaurentis. Jessica found out and forbade Bethany from seeing Ali (CeCe). Bethany started to hate Jessica and she kept seeing Ali (CeCe). In Bethany’s thought, Jessica wanted to keep her away from her new friend Alison (CeCe); Bethany hated Mrs D and expressed her emotions in her drawings.

CeCe was still treathening Ali, signing the messages with “A”. “A” probably was for Alison, because Ali took CeCe place and now CeCe wanted to have it back by taking Ali’s place.



CeCe wanted Ali to go away and she wanted to ruin Mrs D’s life because of Marion’s death, so she started planning That Night. The plan was easy: she wanted Bethany, Ali and Mrs D to meet each other. Ali would have run away because Mrs D prevented her from knowing of Bethany. Bethany would have definitely hated Mrs D. Mrs D would have lost both her favourite girls.

Part 3 - That Night

That night CeCe arrived at the DiLaurentis with Bethany, but they needed to wait for Ali. Bethany started to not well-behave while she was waiting with CeCe, they argued and they ended up fighting. CeCe collapsed right there, while Bethany menaged to go away from CeCe before falling to the ground. Melissa found Bethany’s body and buried her.

CeCe woke up and looked aroud, she saw Ali in front of the DiLaurentis and she hit her thinking she was Bethany.



Mrs D went out of her house blaming CeCe. But CeCe knew of Marion’s death, so they reached an agreement. CeCe then left and disappeared.

Mona saved Ali and she took care of her. Ali told her about A. Mona was already obsessed with Ali, as we can see by flashbacks.

Mona then helped Ali to escape.

Part 4 - the show we know

(Because it is already too long, I skipped some parts of the story to focus on the 5 episodes Marlene suggested to look for clues)



After Ali disapparence, the group fell apart and Mona and Hanna became friends.



One year after Than Night, when Aria came back from Iceland, Mona was scared that the Liars would have came together again and she was afraid of losing Hanna, her only friend. She remembered of what Ali told her and she started to threaten the girls with A’s messages.



The more she tried to hurt them, the more they got closer. She went crazy.

Mona was, at the end of season 2, contacted by an unknown person (CeCe) who ordered her to reveal herself as A because she had bigger plans.

In “Unmasked” (2x25) CeCe made her first apparence. She was the girl in red with that big mask on her face. She went down the stairs without anyone noticing her, so far from when she was the Queen Prom in 2007.



Later in the episode, Mona revealed herself and was recovered in Radley.



In 3x01, Mona got visited by Hanna in Radley. While Hanna was speaking, we see Mona have an hallucination of Ali in a red coat sit in the chair behind Hanna. It is a hint that someone in a Red Coat who looks alike Ali was visiting Mona in Radley. Yep Cece.



CeCe, during season 3, officially appeared as a character inside the show. During season 3 the game passed from Original A to BigA.



In 3x24, there is the Lodge Fire. Mona said “she’s coming" and then she revealed she didn’t know who she was. Red Coat got off the plane and is seeing by Spencer. Someone started the fire. CeCe did not want any other innocent to die, so she rescued all the girls except from Hanna, because she is the copy of Ali and she is becoming the new Queen of Rosewood. Ali was there and saved Hanna.

CeCe killed Wilden because he wanted not to cover Marion’s death anymore and CeCe, right then, needed to have power on Mrs D.



In 4x09 we see Red Coat outside of the DiLaurentis house and we found out about the secret place under the house. I believe this was still part of the agreement CeCe and Jessica did and Jessica was totally aware of having a host.



In 4x23 we see clothes on Ali’s bed. Later in the episode, Mrs D gave a bag to someone in black. In the ending scene, someone with black gloves and the black hoodie called the police denouncing CeCe’s position.The police was seaching her because of Wilden’s murder.



In 4x24 CeCe is wearing at the police station the same clothes we saw in Ali’s room the episode before.



At this point of the story, Mrs D was aware of Ali being alive, so she didn’t need CeCe silence anymore and she couldn’t protect her anymore as well. As soon as CeCe and Mrs D were released from the police station, CeCe killed Mrs D. She then headed for NY, where she met Ali (in 5x01) and became able to leave for somewhere with Ali’s Holly Varjak passport. In this way, she went away from Rosewood and she prevented Ali from leave by taking her passport, because she understood she needed Ali to be destroyed, not just to be away.

CeCe worked to make Ali alone. She destroyed her family and she destroyed her group of bestie. But she needed something more. She needed Mona to be dead and to blame Ali for this. And she needed Mona to suffer, because she was an other queen of Rosewood and, even if she has been torturing the girls and recovered at Radley, everyone was loving her. They planned together all along.

In 5x12, what we see on the screen is not in the exactly order it happaned:

Mona greeted her mum, she went inside and she waited for Leslie, who was standing in front of the entrance.

Leslie came in with the black hoodie and a blonde wig. She helped Mona to fake her death, they recorded the fight with the hidden cameras and then Leslie left to reach Mona’s mum.

Mona greeted Leslie and came back in the house, this time she checked if anyone was following her (this is when she looked outside from her window).

Mona went upstairs and called Aria.

Someone with long blonde hair sneaked inside her house and went upstairs. When Mona realised it, she was terrified. A attacked Mona and took her to the dollhouse.

In 5x13, we have CeCe and Ali dialogue. CeCe said "the first Christmas it is always the hardest when you lose someone” and then “you don’t have to worry about Mona”. This two lines are clues that she lost someone in her life (her natural mum) and that she had the Mona situation under control.

It was the last time we see CeCe on the show.

I believe CeCe was at the prom in the dollhouse. Don’t forget that is was her prom, she was prom Queen in 2007. She made Ali to be prom queen because she wanted to give a message and a hint to the Liars.

Moreover, two mannequines, in particular, are changing their positions. When the Liars entered the room, the mannequines were in this way:

7 seconds later, while “Unmasked” is still playing, the mannequines on the right appeared closer and there is no way it is just a prosective thing:



That white mask reminds me the gold one in 2x25.



I know we are in Rosewood, but i don’t think Charles could menage to move both the mannequine in blu we know he’s hiding behind and those three without the liars noticing any movement.
