Mona is revealed as “A” or part of the “A Team” in Pretty Little Liars for the second season finale, UnmAsked. However, what caught my eye is Aria. I think she is the real A. The creator of the PLL series, Marlene King, even tweeted that A is the “black swan” in the masquerade party. She also said that “red is the new black.” Now take a look at the other promo picture for the “Black Swan” movie! The red and black colors and even the pattern match the dress that Aria’s wearing! The gloves? Well, remember A likes to wear black gloves, too? Also, the title of the episode is UnmAsked, and the only who was actually unmasked during the masquerade was Aria (and okay Ezra too but who cares).
Also, have you guys noticed that Aria has the least sufferings among the four pretty liars? And “A” even tried to help Aria to get rid of Jackie! Aria is also the only one whom Alli haven’t visited in the dreams yet. Plus, she’s wearing the red coat and kept it. Towards the end of the episode, we can see Mona talking to A who’s wearing that same red coat. And if you guys remember, the little kid named Seth in the last episode said that a brunette man and woman visited the creepy doll shop. Maybe he’s talking about Aria and Ezra? And then the old lady shushed the little kid since Aria was there, and have you noticed that when the girls returned to the doll shop, Aria wasn’t there with them? Oh yeah, weird. Plus A usually types the letters that are sent using a typewriter, and in Ezra’s apartment, we’ve seen a typewriter… so what if Aria types it there? Moreover, the note about the “be there…” from A was only in Aria’s invitation, so what if she put it herself there? And she has red nail polish, too!
Plus in the intro of PLL, Aria is the only one who’s shushing, so she’s definitely keeping a secret. There are more reasons why I think she’s A but wow, why Aria why?!
