This show is killing me! & I have a new theory, that I dont know if anyone has ever metioned and also there are a few pieces missing but still I want to get it out. I never ever believed that Ezra is A or A.D. However, there are a few things that I don't understand. Firstly, we know he is an excellent liar. In the first ever episode of PLL Ezra acts super surprised to see Aria in the class room and he says the 'holy crap' unintentionally. But why? He freaking knows who Aria and the other girls are. (I do think that he has a split personality) Also why is it that Ali and Ezra act like they dont know eachother. He wrote a book about her. They have history.. They all choose to ignore that. They were romantically involved in the past and even though Marlene at some point said that Emison is going to happen, I cant stop thinking that Ezra and Ali are going to be on the A.D- Team. Secondly, why does someone need to stalk someone, have a secret lair, watch the girls 23/7 for a effing book? You had a good storyline, why not just go with it and let your fantasy work a little. It seems so odd to me. I really think that he has some kind of mental disorder. Split personality and anger issues are a part of the disorder. I think that he got to know Ali at some point and fell in love with her, maybe even get too much obsessed with her. The stalker that took photos of her and the girls was probably him. I think she made a mistake and slept with him, which caused him to obsess over her more and more. After time, she wanted to get rid of him but he wouldnt let that happen and Ali started to get scared, so scared that she did not have another option than to run away and later fake her own death. Ezra, after finding out about her death, did not want to believe this and probably thought that the other girls knew where she was and started to get involved with them and met Aria and took the opportunity to date her to get closer to the girls. After Ali reappeared in Rosewood, Ezra felt so betrayed that he wanted to take revenge (Also possible: he thought that he needed to get back at the girls for forgetting about Ali so quickly) At this time, he knew about Mona being A and was fascinated by the idea of torturing the girls and decided to play the game. In the process of trying to get revenge he met so many new people: Mary and Cece Drake, Wren, Charles etc etc. They are all on his team because he made them believe that it was time that they finally get the life they deserve. So Ezra with the help of his friends decided to build board game and the dollhouse (there is a scene of the boyfriends trying to track down the girls and Ezra really get angry, kicks the wall and stuff; the reason behind that is probably because one of the Team kidnapped the girls without the knowledge of A.D) And so on. Ezra now got to obsessed with the game that he cannot stop. Probably his love for Ali faded or one persona of his still loves her while the other persona is in love with Aria, idk haha. But what do you think????
