I’m pretty sure she’s involved.

Firstly who is the one that found this corridor from radley sanitarium? ARIA! Spencer was there too, of course, but Aria is the one who had the idea of going to sara´s room and she is he one who found this hallway, where we see those buttons the girls were torture with, which left Aria pretty traumatized as we can see in her reaction.

Also she was the one who realized the file cabinet was with no dust when spencer didn’t even bothered in looking at it, how did aria imagine/know that?

We know from the beginning of the episode that the buttons have some meaning because in the “previously on Pretty Little Liars” they put this (which by the way is from Aria’s perspective, in 6x11)

At the end of the episode while Uber A is cleanning the buttons 

the background music is Whistle While You Work from Snow White do you remember anything connecting Aria with Snow White? no? let’s go back to 6x10 where she dressed as her

As you can see, there are a lot of things that connect Aria with Uber A this episode, I’ve seen a lot theories about Aria having a mental disorder and that being the reason the montgomery’s moved to Iceland, if that’s true, this could be part of her illness.

I found a CLUE coming from the episode of the last week (6x14) In the final scene of the stalker, we see him get into a car license plate: “6.6410”. Well, my crazy mind thought that ‘410’ can mean #4x10, which is the last episode of Wren in the show. Then I said, ‘and if the '6.6’ meant the minutes of the episode?’ Well, I couldn’t believe it but then i went to the exact minute 6.6 of the episode, I find myself at the BEGINNING of the mysterious dialogue between Mona and Wren. Not at first moment of a scene together, where they talk about other things, but just the exact moment when the discussion becomes mysterious and Mona exclaims: “Why would I ever be honest with you? That was before I realized where your loyalties were” 6.6. The minutes of the #410 start exactly with this scene. I’m really insane, or is it a real clue? And I remember, there was a similar clue for Charlotte.

In # 3x20 Spencer is in the sauna at his house, sauna has an error, error indicated with “307320” numbers. Well, #307 is the episode Cece appears for the first time. 3:20 is the exact minute when Cece comes into the show. And in fact, Cece turned out to be 'A’.

I don’t know if I’m a crazy, and now my neurons are just dancing the macarena burned in my brain, but I discovered this for myself, and that it. All this can not be a coincidence.

something a friend of mine, joanna, noticed recently was a silver car pulling away from the church the night charlotte was murdered during aria and ezra’s early morning stroll.

during a rewatch, i noticed hanna mentions lucas drives a silver car now. in both instances, neither of the liars notices it.

hanna: that was you? in the silver jag?

i’m not a car person, but i googled what a silver jag would look like to be sure it was/could pass for the car in 6x12. it does.

most people notice the big white suv that apparently looks like ali’s car, just pulling in, but i think that’s a red herring. neither aria or ezra remember hearing a scream or signs of a struggle, and they left shortly after their walk, which might indicate charlotte was murdered a little before four a.m.

this is not the first time lucas has been driving around in the middle of the night when something happened (3x01). and he also may have been so quick to give hanna a alibi because it provided him one in return. he never says where he was or what he was doing that night.

it’s also brought to our attention lucas is now rich with several homes, including one in rosewood, and could easily be used as a lair and he had a technology company he sold before moving onto gaming apps, both which can put him in the running for uber a again, if he’s not the killer.

something else small, but potentially interesting, lucas says he waved to hanna but she didn’t see him, much like mona did to spencer in 6x11. is that a subtle call back to how the liars used to choose them second, if at all, to each other or alison?

However, I now think that the idea of Charlotte being asked to lie and cover for someone else is actually a high possibility.

Looking back on 6x10 and the very brief moment that we see her in 6x11; Charlotte strikes me as someone who is incredibly meek, innocent (I understand that’s far from an accurate word to describe her but bare with me) and someone who could be manipulated into doing  anything. 

I think that the Big Bad took advantage of Charlotte’s mental health and manipulated her into doing all the dirty work while the Big Bad simply came up with ways to torture the girls and send the text messages out. 

I also think that Charlotte was in love with the Big Bad which would explain the flower in her hand when her body was found as well the fact that she’d do anything for them. The Big Bad didn’t have any feelings for Charlotte but pretended to as a means of getting Charlotte to continue to do her dirty work. 

I also think that it was Big Bad that killed Charlotte and I think that this could be for various reasons:

1- Charlotte was supposed to stay in Radley for the rest of her life and Big Bad was angry with her for going against their wishes so asked to meet up her only to kill her. 

2-Big Bad set up Charlotte being let out so they could start playing the game again. When they met up, Charlotte explained that she didn’t want to be part of the game anymore because she liked her new family and wanted the girls to forgive her. Big Bad got angry and killed her. 

3- Big Bad knew that Charlotte was better and was scared of her telling the truth and going to the police.
