WATCH: Pretty Little Liars Season 6 Teaser is Scary as Hell!

Presumably Pretty Little Liars solved the mystery of who A is in the season 5 summer finale. Now it's time to turn to "Why is A?" While this summer teaser doesn't offer any answers as to the why, it sure offers some insight into the depths of depravity. It looks like A (Charles) has graduated from suspenseful Hitchock nods and gone straight to the very modern, very scary Saw series. So many questions are raised in this 15-second teaser that we hardly know where to begin. We'll just say that, even without make-up (or what's supposed to look like she's without makeup), Shay Mitchell (Emily) is flawless.

One question not raised in the teaser is, "Who will be Emily's girlfriend du season?" We know there will be one!
