My Theory on PLL after the season finale of Season 4.

My theory on PLL after the Season 4 finale.

Who is A? 

The A (the one that scare Alison and harassed the 4 girls in the beginning) is Mona. There is no more A after Mona but Ezra trying to figure out stuff to write in his book which is why he asked Mona for help because Mona is the original A. Then suddenly Mrs. D found out that Spencer thought she is the one who killed Alison and Alison told her mom about A before and Mrs. D thought that the A that scares Alison is Spencer so she thought she would let Spencer taste her own medicine by being A to scare her which is why when Mrs. D is A the target is only on Spencer and the other girls didn’t get anything(Spencer’s wedding dress is the one with the bones and the message, Spencer got dirt in her bed, Spencer got the drugs in her lockers, Spencer got EVERYTHING but everyone else NOTHING). The A with the mask on the roof is Jason Dilaurentis.

Who is Jason trying to kill? 

Jason under the influence of drugs and alcohol hallucinate and thinks that his sister is Cece and he wanted to kill Cece because he probably had an argument with Cece that night while he is under the influence and Cece is obviously wearing a yellow top that looks exactly like Alison’s. When Jason saw Alison walking toward his house he thought that it is Cece and hit her with the rock attempting to kill her maybe because Cece did something to him (that is the mystery that they need to tell us). Melissa and Cece are obviously there and saw everything.

Why Jason didn’t know he was the one that killed Alison?

Jason, like his half sister Spencer, when under the influence he cannot remember what he did and what happened so when he was in that stage, he hit Alison with a rock and then their mother tries to cover it up and probably told Spencer's dad that Spencer is the one that hit Alison with a shovel to protect Jason and of cause Spencer’s dad will do anything to protect Spencer so he thought that Ali’s mom is trying to help him protect Spencer because they once had a fling that produced Jason but Melissa saw everything and that is what she told her father in the Police station.

What happened after Jason hit Alison with the rock? 

Mrs. D told Jason to lie down on the chair while she handles it and tries to bury her own daughter thinking that she is dead already in the backyard so that nobody will think to look for her there then Jason started to wake up a little cause maybe the drugs are wearing off then he saw someone in a yellow top arguing with Melissa and assume it is Alison but it turns out that Melissa is arguing with Cece on what they should do. They argued on if they should tell the police about Jason killing Alison and they came to a conclusion that they shouldn’t tell the police anything because Melissa wants Alison dead anyway because Alison is trying to seduce Ian and Cece after seeing Jason hit Alison with a rock knows that Jason want to kill her and thinks that Jason probably thinks he killed her so she didn’t want Jason to think that she is still alive as he might come after her. The next day, Mrs. D arranged to pour cement on it (Alison’s “grave”) for a pool or something (I cannot remember) as a cover story but she doesn’t know that Alison is no longer down there. 

Why did Jason go away? 

Also like Spencer, Jason slowly start to remember stuff as he became sober and all that. He then realized that he was the one that killed Alison or so he thought (like his mom thinks that Ali is dead and buried her) and he started to drink and do drugs again. This is when Spencer found him and helped him then he thought he is not going to kill another sister or put another sister in harm’s way. He told his mom that he cannot stay there anymore knowing that he killed his sister and that the police in Rosewood is still looking for the person that killed Alison and that is why he ran away.

Why did Jason come back? 

When the police told Mrs. D that Alison might not be dead, she told him that he didn’t kill Alison then he thought maybe Alison saw him and if she did and she talk to the police that he will be caught. So he came back to find Alison before the police found her. He knows that Spencer is doing drugs as well on that night Alison supposedly went missing because maybe Spencer’s dad told Mrs. D and Mrs. D told Jason so he planted the story about Spencer to Emily and knows that Spencer probably couldn’t remember what happened that night as well. He assumes the girls know where she is and follows them so by putting the focus on who hurt Alison on Spencer, it will throw Spencer off her game because she will think that she hurt Alison and that maybe she is the one that Alison ran away from.

How did he find them? 

He followed the police carefully and the police thought that he was concern about the safety of his sisters so they didn’t question him.

Why is Ezra there?

Ezra used to love Alison and he wanted to find out what exactly happened to Alison and ended up falling in love with Aria. So with the two people he loves in trouble with A, he tries his best to help them. He follows the police carefully as well and then he saw Jason (he doesn’t know it is Jason because of the mask and hoodie) so he followed Jason and trying to be the hero.

Why is Mrs. D being buried and by who? 

Mrs. D is being buried by Spencer’s dad because Spencer’s Dad wanted revenge on her lying to him about who killed Alison and tries to frame his daughter for killing Alison. They thought that the 4 girls are missing and he assumed Mrs. D is trying to kill the 4 girls so he kill or hit Mrs. D with something to make her look like she is dead to protect the girls and to make Jason not have anybody to protect him because obviously Jason is mentally ill. (He attempted to kill Alison, he takes pictures of Aria, he is all creepy).
