'Pretty Little Liars': A history of 'A's' messages
As you can see, Hanna has received the most "A" messages over the years, which surprised us, actually -- especially since we know she's "A's" prime target for Season 4.
We also like how "A" has gotten less profane over the years -- and how s/he has more incidents of both threatening bodily harm and helping the Liars out. That "A," quite an enigma wrapped in a riddle.

What do you think, Liars fans? "Pretty Little Liars" returns Tuesday night, June 11 at 8 p.m. ET/PT on ABC Family. We can hardly wait!
