There are only three more days between us and the Pretty Little Liars Season 4 summer finale! And the PLL Powers That Be are really excited for us to see it. What clue did PLL director Norman Buckley recently drop on Twitter?

“Here's a #PLL summer finale clue. It applies to one of the girls,” tweeted Norman, along with a screenshot from the 1941 film noir I Wake Up Screaming. When we see classic Hollywood cinema references, our gut instinct is that it applies to either Aria, who is a fan of classic film, or Spencer,who basically lives her life as if she is in a Spencer Tracy movie.

I Wake Up Screaming tells the story of a man falsely accused of murder, which makes us worry and think it could apply to any of the girls. Will one of them be arrested for Wilden and/or Ali’s murder? If this is the twist the show takes, our money is on Emily  “A” already sent the cops a video with a faux Emily holding up a sign that says “guilty.”

On the other hand, maybe Norman isn’t referencing the film at all, but is literally referring to one of the Liars waking up screaming. With lives like theirs, we’d have nightmares, too.

What do you Norman means by his “clue”? Which of the Liars do you think it refers to? Sound off in the comments below!

Catch the Season 4 summer finale of Pretty Little Liars on Tuesday, August 27, 2013 at 8 p.m. ET/PT on ABC Family.
