We are still recovering from the Pretty Little Liars Season 3 summer finale (Season 3, Episode 12: “The Lady Killer”) but now we have to start preparing ourselves for the special Halloween episode this October.

In a promo for the episode (airing October 23) we see Spencer (Troian Bellisario) and Toby (Keegan Allen) attending the Ghost Train Halloween party together dressed up as a retro gangster couple (Bonnie and Clyde?), Hanna (Ashley Benson) making out with someone who we hope is a now-recovered Caleb (Tyler Blackburn) while made up like Marilyn Monroe, and Aria (Lucy Hale) with duct tape over her mouth. Scary and weird!

Considering that last year’s Halloween episode held so many clues, we will definitely be studying this year’s episode.

Watch the preview below.

Catch the PLL Halloween special on Tuesday, October 23 at 8 p.m. ET/PT on ABC Family.
