Do These 'Pretty Little Liars' Photos Spoil Who Killed Charlotte?

Fans are going nuts over these stills from tonight’s episode of Pretty Little Liars in which we’ll learn who killed Charlotte.

In “Farewell My Lovely,” convinced they know who A.D. is, the Liars gear up for a confrontation. And from the looks of it, that definitely looks like the back of Mona’s (Janel Parrish) head, right?

Spencer (Troian Bellisario), Hanna (Ashley Benson), and Caleb (Tyler Blackburn) team up to investigate and discover new information about Charlotte’s death.

Meanwhile, Mary Drake returns with a gift for Spencer and Alison (Sasha Pieterse).

Oh, and did we mention there’s a photo of Mona carrying purple flowers at the bell tower where Charlotte died?! Janel also recently told us that there’s a definite possibility that Mona is A.D.

Pretty Little Liars airs TONIGHT, June 20 at 8/7c on Freeform.
