The Evil Queen (Lana Parrilla) will show no mercy on anyone in the sixth season of ABC's Once Upon a Time.

Now that the Evil Queen has been freed from Regina, she will be going on the warpath. Star Josh Dallas, who plays David on the series, spoke with Entertainment Weekly about the Evil Queen taking no prisoners in season 6.

"She's going after everybody," Dallas revealed. "She's taking no prisoners. She's really doing some mental manipulation with everybody, and it's going to turn everybody inside of themselves. They're going to have a lot internally to deal with."

As Dallas suggested, the splitting of the Evil Queen and Regina will lead to some general themes of exploration within all of our heroes.

It's unclear if the Evil Queen's wrath will extend to the death of some major characters, but one person who should be safe (for now) is Belle (Emilie de Ravin). The frequently distressed princess is now stuck in a replica of Pandora's Box, with husband Rumple (Robert Carlyle) doing his best to get her out.

But according to showrunners Edward Kitsis and Adam Horowitz, she won't be stuck in there for long. They spoke about this to Zap2It recently, admitting that they are delving into Belle's story as early as the premiere episode.

De Ravin also spoke with Zap2It about her character, talking about how fans will learn even more about her in season 6.

"She comes out of the box. She's back in Storybrooke," de Ravin assured. "And you learn a lot about Belle and her family in the process."

Once Upon a Time season 6 premieres Sunday, Sept. 25 at 8 p.m. ET/PT on ABC.
