'Pretty Little Liars' Season 6 spoilers hinted that after the mysterious 'A' finally revealed with a guy named 'Charles' during the last season, it will continue on the mystery behind the hooded villain.

For now, there are already tons of speculations around regarding Charles' identity. It has been suggested that the guy could be Bethany's twin or Jason's twin, or that he could be Caleb, or even that Dan Humphrey character from "Gossip Girls."

In an interview with Zap2it, Joseph Dougherty, the executive producer of the teenage drama, teased some things that fans should expect. When asked whether Charles a boy or not, Dougherty affirmed that the show had a definite direction, but that direction could go anywhere, saying: "We know what we're doing, but it's impossible to take any possibility off the table right now. I can't say yes or no there."

"Here's my problem right now," he explained, "You're actually identifying things that were done on purpose in order to allow the audience and our rather intense fans to actually figure this thing out before we totally explain it. When we think about these last 10 episodes, we think of it as an amazing puzzle opportunity and if the serious fans get it right even a heartbeat before we tell them what it is, we're going to be incredibly satisfied."

Perhaps, 'PLL' fans should wait for the upcoming season, as what Marlene King said that the Charles story will wrap this summer. Also, we will get to see the Liars graduate, which will feature a time jump probably happen between the summer and winter halves of Season 6.

Meanwhile, 'Pretty Little Liars' Season 6 spoilers teased that one main character is set to return to Rosewood. Paige, Emily's ladylove, who moved to California in season 5, is coming back.

"Not right off the bat in Season 6, but I will say that you will see Paige," King told Zap2It. "I don't want to give away the story -- she's not in the first couple episodes, I'll say."
