Pretty Little Liars’ Rosewood is never creepier than when it’s dark out. After all, any member of the “A” team can blend into the dark a little too easily. However, after a Twitter explosion last night, it looks like the Liars won’t be the only ones in the dark at the end of Season 3.

PLL writer Andy Reaser kicked things off by tweeting a pic of the night shoot — the dim street lamps and a high number of trees certainly set an eerie vibe. But if that isn’t enticing enough for you, Andy followed that picture up by tweeting another, more specific pic a vanity mirror, saying, “Make-up mirror in the woods... mysterious things are happening with @ichadlowe #pll.” Define mysterious things for us, Andy.

We know Chad Lowe (Byron Montgomery) is directing Season 3, Episode 20 … so what could be happening so late in the season in such a dark setting?

When asked who was on set, Andy responded, “top secret.” However, when someone prodded for specifics about the whereabouts of Shay Mitchell (Emily), he said there were “grown-ups” on set tonight.

So what could all of this mean? A night shoot does not surprise up, but why are the adults of Rosewood up so late? And why is the cast top secret? Could someone be returning? Like, say, Dr. Sullivan (Annabeth Gish)? After all, she is an adult. Will we finally see the return of all the parents? Speaking of, where has Spencer’s dad been?

And if the answer is yes, what could bring all of the parents together so late at night? Maybe we’re being negative, but our gut instinct is tragedy. And cops. When in doubt, always expect the Rosewood PD. While you’re at it, expect that they’ll fail the Liars in some way.

What are your theories?

Don’t miss the next new episode of PLL, the Halloween special, on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
