ABC's hit series Once Upon a Time descended upon the D23 Expo today, with creators/executive producers Edward Kitsis and Adam Horowitz revealing new details about the upcoming Season 7. While no footage was shown during the panel, the creators revealed two photos featuring new series regular Dania Ramirez, who is portraying the new Cinderella, the wife of adult Henry (Andrew J. West) and the mother of Lucy (Alison Fernandez). Since there has already been a Cinderella on the show, portrayed by Jessy Schram, the creators also explained why this new Cinderella has come to be. Here's what Edward Kitsis had to say during the panel.

"Dania Ramirez will be playing a different version of Cinderella. If we remember Henry's grandfather is Prince Charming [Josh Dallas], so we have the grandson of Prince Charming with a new Cinderella."

Entertainment Weekly reports that original star Jared Gilmore will return to the series as young Henry, which will show viewers why he left home. Edward Kitsis revealed that since Henry is the author of the first book, he wants to go somewhere where the "happy ending" isn't written yet. This creates new books, which creates different versions of characters we've already seen on the hit fantasy series in the past. Here's what Edward Kitsis had to say during the D23 panel below.

"Henry's the author of the first book, but he wants to go to the place where the happy ending isn't written. What's interesting to us is that these books tell the stories, a lot of them about these classic characters, and as you know for the first six seasons we did twists and turns on them. New books could have different versions of some stories and ways of looking at them that maybe we've seen before, maybe some new characters as well."

We reported in May that series star Jennifer Morrison, who has played the pivotal character Emma Swan since the first season, is leaving the series, due to personal and creative reasons. However, the executive producers confirmed that Jennifer Morrison will in fact return for at least one episode this coming season. The executive producers also hinted that other former stars like Jared Gilmore could be returning, but they wouldn't divulge any specific characters yet. As for all of the "happy endings" many of the characters received in the Season 6 finale, Adam Horowitz made it clear that those have not been "erased".

"They weren't so much happy endings as happy beginnings. We want to make sure we honor what happened over those six years. As much as there's new stuff and new characters, what came before still matters and is still a huge part of what this show is. It's a new chapter."

Edward Kitsis added that, "We're not interested in erasing those six years," while also confirming that Hyperion Heights, the name of the Season 7 premiere episode, is the new neighborhood in Seattle where Henry now lives. He added there will be a new forest, and that fans haven't seen the last of Storybrooke, hinting that they may go back there a few times this season. He also said that they won't reveal whether Captain Hook (Colin O'Donoghue) and Emma Swan had a baby just yet, but fans will find out in the Season 7 premiere, with Hook in Seattle. Here's what Edward Kitsis had to say about Hook possibly returning to his villainous ways.

"There's always the danger of Hook returning to his villainous ways, but I think his good heart prevents him from going all the way. I think that Emma is absolutely Hook's soulmate that we saw, so the Hook we all know and love, how could he look elsewhere? There is no Tinder in Storybrooke, people."

After six seasons, the residents of the enchanted forest face their greatest challenge yet as The Evil Queen, Captain Hook and Rumplestiltskin join forces with a grown up Henry Mills and his daughter Lucy on an epic quest to once again bring hope to their world and ours. Along the way, new fairy tale characters and old search for true love, find adventure, and once again take sides in the struggle of good against evil as classic tales are once more twisted and reimagined. Once Upon a Time stars Lana Parrilla as the Evil Queen/Regina, Colin O'Donoghue as Hook, Andrew J. West as Henry, Alison Fernandez as Lucy and Robert Carlyle as Rumplestiltskin/Mr. Gold. Edward Kitsis and Adam Horowitz are creators and executive producers. Steve Pearlman and David H. Goodman are also executive producers. The series is produced by ABC Studios.
