The seventh season of Pretty Little Liars [1] has already taken us deep into the show's final mystery, and there's no signs of slowing down. The end of the month marks this season's Summer finale [2], and while we've gotten a few spare details, there's no telling what's really in store for the Rosewood bunch. Will we get closer to finding out who killed Charlotte DiLaurentis [3]? Will the identity of "A.D." [4] finally come to light? We'll just have to wait until Aug. 30 to find out.
