What do we know about Aria?
2×22 – She’s good at keeping secrets.
3×07 – We’re pretty sure this was not only an acronym.
5×07 – Eddie Lamb recognized her and she freaked out.
7×15 – A has something BIG on Aria!
Based on the above information, let’s assume the following: Ezra Fitz got his under aged girlfriend, Aria Montgomery, pregnant, but she didn’t tell him, because she got an abortion. She got an abortion, because Ezra was under enough heat just for dating her, let alone getting her pregnant. To get the abortion, Aria went to Radley, because it’s basically a don’t ask, don’t tell kind of place where she knew secrets could be kept. Of course, she wouldn’t know for a while how many and dark of secrets Radley could keep, but she knew Radley could keep secrets. After her abortion, Mona found out; or CeCe found out and told Mona, because well they were both A at one point. Mona used this information as a scare tactic for Aria. A few months later, Eddie Lamb noticed Aria at Radley and she pretty much immediately freaked out. Let’s assume Eddie Lamb, who was a nurse at Radley, was there when Aria got her abortion. As Aria and Ezra started to work closer with Eddie, he disappeared. Let’s assume that’s for two reasons. 1) CeCe didn’t want him telling her secrets. 2) Uber A was saving Aria’s dirty little secret for a special occasion. Now, of course, we know that that special occasion was to get Aria to work with him/her. Maybe Uber A would have drawn Aria in sooner, but didn’t have the necessary evidence to reel her in? Idk, but he/she did wait. Of course, because Aria is the liar with the biggest heart–Emily is the most loyal, but Aria feels most deeply–A knew that with the right evidence, he/she could get Aria to do almost anything.
Or, we can get even darker…. what if Aria and Ezra really did kill someone? What if Eddie knew and she killed him too? Probably not, but you know… it is Rosewood!
