On Saturday, Once Upon a Time invaded Comic-Con with its particular brand of madcap magic. The panel boasted stars Ginnifer Goodwin, Jennifer Morrison, Robert Carlyle, Lana Parrilla, Josh Dallas, Emilie de Ravin, Colin O'Donoghue, Sean Maguire and Rebecca Mader, along with co-creators and executive producers Edward Kitsis and Adam Horowitz.

Fans were treated to multiple video clips, but the two most intriguing were looks at what's to come in Season 5.

First is a sneak peek of Emma as the Dark Swan. We see a jailor enter a dark, wet dungeon with food for an unknown prisoner, who is then revealed to be Emma. She's changed her look - hair is slicked back, her clothes are black and she has a lot of face glitter going on. See for yourself how the interaction turns out:

The panel also ended with a clip, which introduces the next Disney character to visit our Storybrooke pals:

We'd recognize those fiery red curls anywhere! Yep, Once Upon a Time meets Brave's Princess Merida next season. Now that we've seen her, we can't wait to hear that Scottish accent! And yes, the actress is Scottish. That's Amy Manson, who you may recognize from Torchwood, Being Human and Atlantis.

Here are a few other highlights from the panel:

Why people stay Fans were treated to a mockumentary about why, when Storybrooke is the most dangerous place ever, people insist on living there. The interviews with an accountant, the daughter of the blind witch from Hansel and Gretel and the former goddess Freya were hilarious set in such a mundane context. Jane Espenson wrote the fun piece, and we're hoping it will be released soon.

Henry the Author Even though Henry snapped the quill in half, he's still the Author. Kitsis and Horowitz hinted that he'd probably be haunted by that decision.

What a doll Six of the Once Upon a Time characters will be made into Funko Pop! Dolls. You can get your big-headed, beady-eyed versions of Emma, Hook, Snow, Charming, Regina and Rumplestiltskin in early October.

Where and when is Camelot? This coming season will travel to Camelot, but how does it fit in with the show's timeline? Horowitz said, "Camelot exists in a parallel timeline. It's existed long ago, short ago, present ago and maybe in the future." Clear now?

Make a wish A fan asked O'Donoghue what he'd ask for the Author to change if he had a choice. "Let me answer that as Captain Hook," the actor said. "Let me have two hands... that way I can feel things with my left hand. Hey! I didn't actually mean to make a joke there."

Can Hook help? Now that "Hook has been battling darkness for hundreds of years and he found love with Emma, he's desperately been trying to hold onto that and keep her heart safe... but he has been a villain, and his girlfriend is nasty now. So who knows what's going to happen," O'Donoghue said.

Zelena love Mader says that Zelena is the best role she's ever had. "I love playing someone so batsh--crazy... the reason why it's so easy to play someone so awful is that she thinks she's delightful," she said.

The eyes have it After playing a bad guy in last seaon's Heroes and Villains episode, Dallas said, "I was against the guyliner for a long time, but now I kind of like it."

Robin's true love Maguire said that "He's pretty madly in love with this one [Regina]. Robin got a lot of flack for impregnating Zelena, but he didn't know it was Zelena... he was trying to do the honorable thing... but life is messy and complicated, so he has to now follow his heart."

Regina evolution Deep down, she felt that "she could never be truly happy" and that's why she did so much evil. But being surrounded by heroes changed this perception. "And she found love," Parrilla said. "I think she now accepts that she can be happy."

Belle needs a break After last year's troubles, de Ravin said she would like to see Belle get a vacation.

Are you psyched to see Princess Merida on the show? How awesome does Emma look as the Dark Swan?

Once Upon a Time returns on Sunday, Sept. 27 at 8/7c on ABC.
