Ashley Benson's (Hanna's) big sister Shannon may have jokingly posted this suspicious photo of her dogs holding "Who Is A" signs, but we can't help but wonder if there's actually some truth behind the funny image.

The photo (below) shows the Benson's dogs each with a different "A" suspect name: Ezra Fitz , Mona Vanderwaal, Melissa Hastings, and Jenna Marshall. Along with the photo, Shannon wrote, "Monday is A day so...Chloe (L) is asking the dogs Olive, Phoebe & Daphne. Who is A? lol"

Could Ashley have given her big sis a hint as to who "A" is, or is Shannon just speculating like the rest of us?

We'll find out soon enough on the Pretty Little Liars Season 2 finale on Monday at 8 pm ET/PT on ABC Family.
