In case you're still not convinced that Mona (Janel Parrish) is the real driving force behind "A", Marlene King tweeted an interesting hint about just how powerful Mona was last night after the premiere.

"A/Mona did all but two things that were done to the PLLs. Guess what those 2 things were? And who did them?," she said.

Well, we're pretty sure that one of those things was the creepy, creepy back massage Emily (Shay Mitchell) received during Season 2, Episode 10, "Touch By an 'A'-ngle," since that seemed to take place at the exact same time Mona was off spending the day with Hanna (Ashley Benson) and Kate, and while Mona is clearly good, we're pretty sure she's not so good she can literally be two places at once.

Which cruel acts do you think weren't carried out by Mona? And who did them? Could it be the person she was talking to at the end of Season 2, Episode 25: “UnmAsked”? Weigh in at our Facebook page.
