Aria is A.D I'll fight you on it
I’m still keen on the Aria is A.D/uber A theory. It does add up.
My theory is that at some point, perhaps after Alison went missing, Aria had some kind of mental breakdown and was in Radley. Whether or not she actually went to Iceland I don’t know. It would be a fair cover for being in a mental institution. This would explain why Eddie Lamb recognised her when she volunteered at Radley. She did seem pretty surprised and uneasy when Eddie recognised her.
Also, another major point is the fact her medical files were missing but all the other girls’ files were still there. Then at the end we see A with Noel and Aria’s files. Why Aria? Unless she stole it herself or is working with Noel (unless he’s dead, I can’t remember lol). Even Ezra would do something like that. There’s obviously something worth seeing in it. What if it was records of a mental illness or her stay at Radley? I’m pretty sure the girls might have a few questions for her if that is the case.
I just wonder why they aren’t acting more suspicious towards Aria now. One, we still don’t have definite proof that Aria and Ezra didn’t kill Charlotte. Aria was the only one to say she wanted Charlotte to stay in Radley. Maybe she truly was scared and she killed her out of fear and anger. Aria does tend to have violent, explosive outbursts, sorta like Charlotte. It wouldn’t surprise me if she did kill her. Maybe she killed her because she wanted to take over the game.
Aria seems to be the most affected by what happened to them. Or that’s how the portray it at least. Maybe it’s all just a cover and Aria has been the real A since episode 1. Mona started it, but Aria and Mona have an interesting relationship. Mona did call Aria ‘big A’ in like season 1 or 2. If that’s not a dead giveaway then idk what is. They don’t seem to hate each other, it just feels like there’s something unspoken between them. There’s a lot of little looks and queues they make, and when they work together they are a pretty good team. Aria is the best liar of them all, she’s secretive and mysterious. All key traits a psychotic stalker/abuser would have. Mona even respects Aria in a way, like that time they were at the movies and Aria said something into Mona’s ear that made Mona cry. Mona said something akin to 'you know where to stick the knife and how to twist it’ meaning she didn’t just go for the kill, she doesn’t mind letting the victim suffer a bit too. To me this was a big moment. Not many people can get Mona to break with just a few words. Maybe we weren’t meant to hear it because it had something to do with the A game? That’s unlikely but just speculation.
What we do know is that Aria has massive potential for being a much darker character, all the prerequisites are there. I’m not psych but I am studying to become one, and I would be pretty concerned about Aria, even from season 1. She’s volatile, her moods change very quickly, she gets irritable and impatient easily, she’s destroyed other people’s property in her anger outbursts, she’s very paranoid and suspicious of people and in general, she looks in the mirror a lot which I used to do when I was going through derealisation and depersonalisation. It’s a strange feeling, but I suffer from anxiety, depression and bpd, and I know the signs of dissociation. Aria is the most likely suspect in my opinion. She dresses eccentric which could be from a lack of self image, some speculate that she has DID dissociative identity disorder formerly known as split personality or multiple personality disorder. This could be true, but I feel like at least her parents would notice her changes and get her some help. Who knows? After all it is just a TV show.
I feel like she has something similar but on a lesser scale. Severe anxiety can cause paranoid thinking and even hallucinations, but that would be at the point of psychosis. Psychosis can form as a result of trauma, which Aria has certainly experienced. Spencer had her thing with the meds, Emily and her drinking, Hannah and her drinking, what about Aria? Maybe her trauma manifests differently, in the form of mental illness. Mental illness cannot always be detected easily, and I mean by others who you spend time with. They won’t always notice and sometimes the sufferer will purposely hide it because they’re embarrassed or whatever. Aria could be aware of her illness and now she’s better at hiding it. All the evidence is against her. Guilty, I say. I say, you are A.
