ONCE Upon A Time Producers Finally Reveal All

At this year's San Diego Comic-Con it was revealed that Scottish princess Merida from Disney/Pixar's "Brave" will be a new character on "Once Upon a Time" in season 5. She'll be played by Scottish actress Amy Manson ("Being Human," "Torchwood") and will appear in the season premiere this fall on ABC. The series creators Adam Horowitz and Edward Kitsis dished on the character's involvement in the new episodes.

"[Manson's] already shot some stuff," Horowitz said at Comic-Con, according to TVGuide. "She becomes very much a part of the story as we pick up with Emma being the Dark One and Emma's family trying to help her not be the Dark One."

"You don't bring Merida on and not let her shoot her weapon," Kitsis added. "Merida really fits in. You see her with Snow, you see her with Ruby, you see her with anyone."

But one connection that doesn't exist is the speculated mother-son relationship between her and Rumple. The former Dark One's mother will appear in flashbacks in season 5 and is also Scottish, but Horowitz and Kitsis told Hypable that Merida isn't her.

A sneak peek reveals Merida and her skills with a bow and arrow. Watch it below:

Some other new faces next season include King Arthur, Guinevere and Merlin. The role of King Arthur will be played by British actor Liam Garrigan, Entertainment Weekly reported. Garrigan has appeared in "24: Live Another Day," "Strike Back" and "The Pillars of the Earth." The actor will make his first "OUAT" appearance in the season 5 premiere. Elliot Knight ("How to Get Away with Murder") has been cast as Merlin and Joana Metrass ("Sinias de Vida") will play Guinevere.

"As we do on 'Once Upon a Time,' we're doing our own twist on Camelot, on Arthur's background and on his relationships with Merlin, Guinevere and Lancelot," Horowitz and Kitsis stated.

"Once Upon a Time" turns to ABC this fall on Sunday, September 27 at 8 p.m. ET

"Once Upon a Time" season 5 is still underway and won't premiere until this fall but ABC has already released the titles of the first two episodes, "Dark Swan" and "The Price." According to a report from the IBTimes, the titles give a big hint on what's to come.

"Dark Swan" is an obvious reference to Emma Swan (Jennifer Morrison) as she is now being consumed by the Darkness after she sacrificed herself to save Regina (Lara Parrilla).

According to a report from Enstarz, the character is now free "in the darkest way you can imagine." Morrison described her character as "completely selfish and completely free of her responsibility" and, at the same time, "almost sociopathic in a way."

"Free" is the term that Morrison used to describe Dark Swan because now, the character no longer has to worry about saving other people or about being strong since she was often the one that the companions looked up to. She is no longer weighed down by the duty of doing the right thing.

"The Price," meanwhile, might be hinting at what the costs might be to bring Emma back from the darkness. According to the IBTimes, this could refer to either Henry (Jared S. Gilmore) paying the price if he attempts to change their fate now that he is the Author, or Hook (Colin O'Donoghue) trying to save Emma, no matter the consequences.

This might lead to Hook becoming a villain once again or it could mean something else entirely. It does paint the picture that whatever the good guys need to save Emma may be introduced in episode 2, and it will likely be found only in Camelot, which is the setting for season 5. They might need Merlin's (Elliot Knight) help in finding it.

"Once Upon a Time" season 5 premieres this Sept. 27.
