However, the Liars' run-ins with 'A' have furnished them with a surprising amount of information.

"I would try to not read that much into it, but I think Hanna pointed it out that there was some athletic ability to that person, and when she said, 'That's definitely not your mom,' I think we can read at least that into it," said showrunner Marlene King in regards to the alleged rooftop 'A', according to Entertainment Weekly. "That wasn't Mrs. D jumping from one roof top to another. As much as Andrea Parker probably could do that - she is a pretty little hottie!"
