Promo for 3x13: "On October 23rd, All Aboard the "A" Train"

Here's the promo for 3x13 This Is A Dark Ride, airing on October 23rd!

Some clues from the promo

• A good glimpse at all four of the Liars outfits for Halloween! Looks like Spoby aren't going as Jack and Rose from Titanic, as Bryan previously warned us about! Hmm...
• Hanna looks solidly as Marilyn Monroe, Emily's clue is Barbarella and for Aria, we couldn't see much of the outfit, but we know it's Gatsby-inspired!
• We spy an Adam Lambert in performance on the ghost train!
• Looks like Haleb is still going strong, making out on the Halloween train! Or is that really Caleb? It's difficult to tell!
• Is Aria "A"'s new target, considering her mouth is taped up and she's screaming for help?
• Who is wearing the creepy Alison-like mask? Another member of the "A" team? Or someone else?

What are you most excited for?
