Wanna know what goes on in the mind of “A” on ABC Family’s addictive hit Pretty Little Liars? Well, then you’re in luck: Tonight, all the Little Liars out there who will be tuning in for the show’s special Halloween episode at 8 p.m. ET can chat about everything that goes down with star Janel Parrish — a.k.a. Mona, a.k.a. the super-sleuth “A” — right after the show airs, via a tweet chat brought to you in part by EW.

From 9 to 10 p.m. ET — that’s 6 to 7 p.m. PT — Parrish (whose Twitter handle is @JMeilanixo) will be taking fan questions in a live chat via Twitter. Use #AskPLL to follow along a live-tweet led by Parrish, who will be available to answer any and all questions you have about what appears to be a very high-stakes Halloween episode. (Here’s what we know: Someone will die!) After such a suspenseful hour of television you’re bound to have a handful of questions — and who better to answer them than “A” herself? The girls of Rosewood would be so jealous.

Questions that might be good to find out: How does Toby fit into the “A” world? How is he helping original “A” Mona? What are her future plans for Spencer, Emily, Hannah, and Aria? Log onto Twitter at 9 p.m. ET tonight to find out all the juicy scoop and answers to your burning questions.
