Pretty Little Liars Takes Out an A.D. Traitor and Adds to the Body Count

Pretty Little Liars has added another person to its body count.

The only things we know for sure are that Archer Dunhill is not A.D. or still alive and that A.D. is the deadliest threat the Liars have ever faced.

The Liars are still chasing their tails as they try to keep Archer's body covered up in the woods.

What is it going to take for them to start playing smart instead of always playing catchup?
