It seems there may be more to Mona’s (Janel Parrish) story, if Pretty Little Liars’ showrunner Marlene King’s most recent tweet is anything to go by. Mona told the Liars in the Season 3 finale that she doesn’t know who Red Coat is... but can we trust her?

“401 answers this,” Marlene tweeted on Saturday.

We were willing to take Mona at face value this time (our mistake, this one’s always wearing a metaphorical mask), but this tweet calls our kindness into question. Could Mona be lying about not knowing the identity of Red Coat? And, if she is, why? Is Mona getting in with the Liars part of Red Coat’s master plan?

We’re hoping the Season 4 premiere, “A Is for A-L-I-V-E,” gives us more answers than the Season 3 finale did. Marlene and the other PLL Powers That Be are making quite a few promises - the answers to who pushed Ian off of the bell tower in Season 1 and what happened on the Halloween train, for example. We’ll add this one to the list.

Do you think Mona knows who Red Coat is? Sound off in the comments below!
