Comic-Con: 'Once Upon a Time' Team Teases "Pure Evil" Queen, "Secrets" About Hook's Past

Once Upon A Time - Comic Con Panel - H 2016

Fans of Once Upon a Time who thought that the Evil Queen was bad before haven't seen anything yet.

The cast and creators behind the ABC fantasy drama appeared at Comic-Con Saturday to tease the upcoming sixth season. Once Upon a Time's fifth season ended with the Evil Queen  newly separated from Regina (Lana Parrilla taking the Dragon's heart and declaring war.

"The Evil Queen is slightly different than she used to be," Parrilla told the crowd. "She is now without a conscience so she is pure evil and a lot of fun."

Regina, on the other hand, "is desperate to really be this hero and be happy internally, deep down inside," Parrilla said. "It's going to be an interesting journey this year to see how the two versions of Regina, Regina and the Evil Queen, co-exist."

Although Regina is now split from the Evil Queen, she will still have an edge. "Regina's still sassy. She's not going to lose her sass," Parrilla said. "She's sarcastic and that’s what we love about her. She's not going to lose that."

The split between the Evil Queen and Regina will also add another layer to Regina's growing bond with Emma (Jennifer Morrison). "They're working together and I think Emma has really helped Regina get to this new place in her life," Parrilla said. "And I see that continuing down that path."

Morrison said it will be difficult for Emma to figure out how to stand by Regina but fight off the Evil Queen.  "I think its going to be complicated for Emma to navigate because she wants to believe in Regina," Morrison said. "She knows she needs to protect everyone she loves.

"How do you separate the two mentally and figure out where to draw the line?" Morrison continued. "It's going to be complicated like it always is."

Co-creators Eddy Kitsis and Adam Horowitz also said the show will also delve further into the Regina-Snow relationship in season six. "It's something that we do start to explore even more this season," Horowitz said.

"We're going to see very early on, we're going to see that relationship further. Regina has, for the very first time, a group of people to support her while her other half is going to try to kill everyone and cause a lot of mischief," Kitsis said. "The Evil Queen, if we remember  the one thing she wanted most in the world was Snow's heart and that will not stop."

In addition to the changes ahead for Regina and the Evil Queen, the question also arose about how Hook's return from the dead will impact him and his romance with Emma. "I think he's still pretty much the same Hook," Colin O'Donoghue said. "Now that they know it's true love with Emma and Hook… they're trying to figure out how to navigate that."

There might be some bumps ahead for the pair, however. "I think we might find out a few things about his past," O'Donoghue said. Horowitz elaborated, teasing "some surprising secrets that have been harbored."

In addition, Horowitz teased a "fun arc" for Hook and Charming (Josh Dallas) coming up in season six. "There's going to some fun times to be had, it just depends on what your definition of fun is," Kitsis said.

The panel ended with the opening scene from the season six premiere, which introduced Aladdin and Jafar and received thunderous applause from the crowd.

Once Upon a Time's sixth season premieres Sunday, Sept. 25 at 8 p.m. on ABC.
