PLL Episode 2x15 - A Hot Piece of 'A'

Clues in this Episode that Aria is A

[2x15] Mona to Hanna: "Han, did you really order 12 pizzas with green peppers on them? Noel's allergic!”
[2x18] Holden to Aria: "Wanna get a large pizza to split? I'll even order your favorite, green peppers right?”
Hanna is throwing Caleb's surprise party and  Mona asks her "Han, did you really order 12 pizzas with green peppers on them? Noel's allergic!". Hanna admits to Mona and Noel that she did not order it. Hmm, I wonder who messed up the order? Looks like an -A move to me!! Three episodes later, Holden, an old family friend of Aria's, and Aria go out to an arcade. Holden knows that both of them were going to be there for a while waiting for their parents to come pick them up so he suggests that they order some pizza and play some games they enjoyed when they were little at the arcade. Holden remembers that Aria's favorite topping on her pizza is green peppers.  How ironic that -A and Aria love green peppers on their pizza! Remember that Aria couldn't go to Caleb's surprise party because she was grounded. Aria could have easily called and changed the order on the pizzas to mess with Hanna!
