The 'Pretty Little Liars' Halloween special is airing today, (Oct. 22) and to hold over its fan base for the show's hair-raising episode, the cast and crew have shared some juicy tidbits about the ABC family drama and its spin-off 'Ravenswood.'

It goes without saying that this post will contain spoilers for upcoming and past 'Liars' plot lines. Keep reading if you dare.

The Brainy Spencer Hastings, played by Troian Bellisario teased, "We’re going to meet the cast of the new show for the first time during the Halloween episode — and then the 'Ravenswood' premiere is on right after! I think it will be the only crossover between all of our characters and all of their characters. So this is going to be a whole new world."

Just don't be jealous of Bellisario and the other Liars on the cast. They are as in the dark with the plot twists as the audience and their characters to keep things slightly more organic.

"We’re allowed to know absolutely nothing. When we get to the table read is when we find out what’s happening in the next episode."

And for you lovers of the fashion on the show, the Halloween episode will be full of period costumes from the Victorian and Edwardian period.

As if all that wasn't exciting enough, executive producer Marlene King (who we should note loves to troll the 'PLL' fan base) teased of the episode tomorrow, "You can't miss it. You can't not tune in. It's by far the best Halloween episode we've ever done, but it's also the most unforgettable episode of 'Pretty Little Liars' that you could imagine. It's sort of what we've all been waiting for. There's something that happens in this episode that we've all been waiting to see."

Could this cryptic thing have something to do with Ezra stumbling through A's seeming hideout on a rampage after the girls found the base of operations only to don a vintage military outfit in the last episode?

As one fan sussed out from King, "Like we've seen in the past with our mysterious Red Coat, there is more than one soldier costume running around the Ravenswood cemetery bash. Pay attention to his face because you'll be seeing him on your TV screens quite a bit over the next few months!"

And for you Haleb fans who love the chemistry between Hannah and Caleb (who will be moving to the spin-off 'Ravenswood'), actor Tyler Blackburn says, "It’s not the end [for them]."

"Hanna actually asks Caleb to stick around and help Miranda [a girl he finds a strange connection with on the way to Ravenswood], and that’s where 'PLL' ends and 'Ravenswood' picks up. Caleb starts to realize he’s gotten into a lot more than he thought."

What do you think Little Liars -- will Ali actually come back from the dead? Is Ezra A? Or are all these clues just yet more red herrings from the real red coat?

Tune in tonight at 8PM EST on ABC Family to find out!
