As you probably know by now, tonight's episode of Pretty Little Liars, Season 3, Episode 5: “That Girl is Poison,” revolves around a big birthday bash for none other than Jenna Marshall (Tammin Sursok). But what can we expect at the first party of the season? Showrunner Marlene King dropped a few clues.

When asked to describe the party, Marlene chose "maddening." We know the party is Mad Hatter themed, but we wonder if it has maddening aspects that extend beyond the Alice in Wonderland reference. Will it add another layer of mystery? Will the girls come close to finding a clue but ultimately fail in their plans to uncover more info? Will something crazy go down? Knowing Pretty Little Liars, the answer to any and all of those questions is probably "Yes."

A fan also asked Marlene to describe Jenna in the episode, and Marlene said, "Insightful." Hmmm … is it possible Jenna will actually have something helpful to say to one of the Liars?
