Judging from the physique of the person who jumped to the next roof, A was a tall athletic person. Based on that + who Ali's mom would protect, I think it's Ali's brother. He was in the creepy video club, right? I forget most things about the creepy video club. Obviously the person who jumped was a stunt actor so it's probs irrelevant what they looked/walked like. I still think Paige is A. I don't think Mona is A because Mona doing all these A-type things but for her own social-climbing needs is so much more fascinating and nefarious than actually being A.
