If you're dying to know who the real "A" is on ABC Family's "Pretty Little Liars," you have about one more season to go before you'll get an answer. The cast of the popular drama sat down for a fan-tribute Halloween special, titled "We Love You to DeAth," to discuss what's in store for the remainder of Season 5 and the upcoming Season 6.

Creator Marlene King confirmed that the true identity of "A" will be revealed before Season 7 starts, according to Hollywood Life.

"I think fans got a little worried when they found out that we were going seven seasons, because they thought maybe they're going to have to wait that long to find out who 'A' is, but I am promising you that you don't," King said, according to The Hollywood Reporter. "The identity of Big 'A' is going to be revealed before season seven starts."

Ashley Benson (Hanna) and Troian Bellisario (Spencer) teased that they already know who "A" is. Shay Mitchell (Emily), Lucy Hale (Aria) and Sasha Pieterse (Alison) said they have not been clued-in on the stalker's real identity.

Following the Halloween special, ABC released an official sneak peek at the Christmas episode, which could be deadly for one liar. The Christmas episode, titled "How the 'A' Stole Christmas," will see Emily, Aria, Spencer and Hanna try to clear Spencer's name, according to the Christian Post.

The girls will also try and find a "connection between Alison and Bethany," while Alison gets a visit from Mona's ghost (Janel Parrish). Mona was killed in the summer finale.

"She's going to be the Ghost of Christmas Past, Present and Future," Parrish said, according to Christian Post. "She gets to mess with Alison - and in a fabulous costume, I might add."
