As the Pretty Little Liars Halloween special (Season 3, Episode 13: “This Is a Dark Ride”, airing October 23) approaches, Lucy Hale (Aria) has revealed another juicy spoiler from the episode.

Lucy tells E! that if she had to describe the Halloween episode in three words, she would say “Adam Lambert, which is two words.” After laughing, Lucy filled in the blanks. “OK: Adam Lambert, a box, and red lips.”

Wow, those are some seriously cryptic clues. We already know that Adam Lambert will be singing at the Rosewood Ghost Train Halloween party, which takes place on a literal moving train. But what about the other two hints?

When we think of a box on PLL, two things come to mind. There’s the box where Alison (Sasha Pieterse) used to store her personal items, like her doll with a note from “A” inside, and a big wad of cash. And then there’s the slightly larger box which used to hold Alison’s body before it was mysteriously robbed. Either way, we’re hoping the “box” has something to do with Alison.

As for the red lips, that’s tricky, since according to these sneak peek photos all the Liars appear to be wearing red lipstick. Maybe we’ll see a kiss mark on a new note from “A,” or one of the creeps wearing the monster baby costumes will accidentally leave red lipstick behind, and we’ll be able to narrow down the suspects.
