~PLL Aria PArt of "A" teAm - Based on Camp Mona & events shortly after: THEORY/CLUES
**EDIT: Thanks to fan, Cathy Patton for pointing out that Aria was with the girls when Hanna was hit by the car. I have changed this theory around a bit to make it work with Ezra behind the wheel instead, or Mona because she was taking orders from Ezra.** At Camp Mona, when Hanna was trying to figure out who "A" was, she saw Aria and Ezra. Noel saw them as well. Aria mu st have known, before Hanna revealed this to the girls, that Hanna saw Aria and Ezra, because this would have been easy to figure out thanks to Hanna's calls to Aria right when Noel was writing "I See You" on Ezra's car. It should have been obvious to Aria that Hanna saw what happened between her and Ezra, and at this point Aria was still keeping everything with Ezra a huge secret.
