It’s already been confirmed that the very special Halloween episode of Pretty Little Liars will be flashback-heavy, but some recent tweets from cast and crew suggest that it’s going to be secrets-heavy, too. Over the weekend, cinematographer and director Dana Gonzales took to Twitter to explain that he couldn’t tweet out pictures, because everything on set was so sensitive:

@danagonzales: It is very hard for me to post pictures because their are so many secrets all over the place.. I will try my best #PrettyLittleLairs

He also tweeted a big hello to Brendan Robinson (Lucas Gottesman), who will feature in the episode as well. But the biggest spoilerific detail comes courtesy of showrunner Marlene King, who wrote that the girls will be attending a big Halloween bash hosted by resident creeper Noel Kahn (Brant Daugherty):

@imarleneking: On set with all four Pretty Little Liars dressed foe Noel khans over the top Halloween party. "Come prepared to be scared."

Trick or treat, bitches — we have a feeling that this is going to be a Halloween to remember!
