EXCLUSIVE: 'Pretty Little Liars' Boss Promises 'Heads Will Roll' in 'Craziest' Summer Finale Ever!

Pretty Little Liars may be ending, but we’ve still got to get through tonight's shocking summer finale!

Now that we've already swooned over the episode's most heartfelt confession, it's time to focus on the most cutthroat moment: Rosewood's next victim.

"It's definitely one of our craziest finales ever," executive producer Marlene King spilled to ET's cameras earlier this month at the Television Critics Association press tour. "In terms of what the big set piece is and what the danger is, it's one of those situations where you feel like heads are gonna roll."

"Heads will roll in this one," she coyly stressed again. Hmm… what an interesting way to phrase that one, Mar!

In addition to her head-turning tease, King confirmed that there will be "at least one" death in tonight's finale and it's guaranteed to add to her grand plan to make this the "deadliest season ever."

"We can confirm that there will be a death and, in addition to that, the fate of several other characters definitely sort of hangs out there," King said.
