“Once Upon A Time’s” terrific Season 6 finale left fans satisfied… and wondering what happens next. EW got executive producers Adam Horowitz and Edward Kitsis to talk about it.

The Final Battle led to a lot of loss during Sunday’s two-hour season finale of Once Upon a Time.

After the curse hit, Henry (Jared Gilmore) found himself in a Black Fairy (Jaime Murray) run Storybrooke where Emma (Jennifer Morrison) was locked up in a mental hospital, unaware she’s the savior and refusing to believe in fairy tales.

It turns out, the Final Battle is not an actual fight, but a battle for Emma’s soul. The Black Fairy hopes to crush Emma’s belief, thus causing all the realms in Fairy Tale Land to crumble and disappear — and she nearly achieves her goal, too. Though Emma initially returned to her old life in Boston, Henry was able to convince his mother to return, saving everyone’s lives.

But it’s Rumple (Robert Carlyle) who actually breaks the curse. Furious that the Black Fairy imprisoned Belle (Emilie de Ravin), Rumple killed his mother, thus ending her spell, returning Emma’s memory and bringing everyone home to Storybrooke. Unfortunately, the Black Fairy had already commanded Gideon (Giles Matthey) to kill Emma. Instead of fighting back, Emma decides to sacrifice herself rather than kill an innocent. But, in a scene echoing the season 1 finale, Henry’s kiss resurrects Emma.

Though the storybook was burned, it reconstitutes and subsequently ends. Yes, it’s the end of this book, but not their story. Everyone gets to keep living happily ever after together. And yet, in a flash to the future that echoes the pilot, a young girl named Lucy (Alison Fernandez) shows up at an adult Henry’s (Andrew J. West) door, exclaiming that his family needs his help. She’s the same little girl whom an adult Henry in the Enchanted Forest employed to protect the storybook when a darkness came for him in what turned out to be a flash forward. What does this mean?!

ENTERTAINMENT WEEKLY: Many of the cast we’ve known over the last six seasons are not returning. Can you talk about how the story will be changing moving forward?
ADAM HOROWITZ: Just on a conceptional level, it’s the same show. We’re trying to tell the same kind of stories and honor the DNA of what Once Upon a Time was from the very start. But I think we — Eddy and I — felt that as we approached season 6, the time had come to close the chapter on a lot of the stories we had been telling, which was the impetus behind this season finale, and open some new chapters. While there are some characters returning and some not returning, it’s still the same universe, and it’s still the same kind of storytelling. It’s just that we’re going to be coming at it from a little bit of a different angle. It’s not going to be necessarily Storybrooke-based.
EDWARD KITSIS: Also, what we see is, a new hero is leading us into a new world, which is an adult Henry Mills. We saw that in what we realize are flash forwards, and then at the very end, Henry has grown up and he looks like he left home. He was an Author writing everyone else’s story, so to me it looks like he left home to find his own story and then something happened, and now he’s got to be the hero.
HOROWITZ: It’s a little bit of the continuity between the two iterations of the show, which is Henry. Henry has been the heart of the show from the beginning. Jared was amazing, and we couldn’t love him move; watching him grow up has been amazing. Now, we’re going to see what that character becomes in a 10-years-older version. But he’s still going to be that character and still carry that essence of the show and be the center of the family that’s at the heart of the show.

You gave so much closure to so many stories, how do you plan to reconcile that with some people returning next year but not others? Does that change their happy endings?
KITSIS: What happened to these people, those are episodes, those are things we will probably want to show. For us, we felt creatively it was time to end a lot of these stories. What we’re really interested in is, as we said, it’s like a new book. So we’re starting with new stories. Although it’s going to have some of the people that we’ve loved for six years at the center of it, we are going to meet new people and new worlds.

Will we see an influx of new characters and other fairy tales? How will you branch out in that sense?
HOROWITZ: Hopefully when you see the premiere, that will become super clear, so we don’t want to give too much away right now other than to say we do intend to branch out, we do intend to also stay with some of the characters we’ve been with. It’s about how do you honor everything that’s come before, but also widen the canvas a little bit?
KITSIS: Open the world up.
HOROWITZ: That’s the goal of season 7. In addition to the people that we’ve already announced who are coming back as regulars, and who are not, there will be more regulars we’re adding to the mix.
KITSIS: As we completed one journey, what we want to do next year is take people on another one. The DNA is still the same, which is fairy tale characters in the real world in search of hope. We still have Henry, we still have Regina, we still have Hook and we still have Rumple, and we still have people are that are going to come in and out that we know, but we’re going to meet a whole new universe and a new group of people. So for us as writers, we’re also excited to do that. Probably you’re going to see a world with no magic in it on one side, very similar to the way we did in season 1.

Thematically, what are you hoping to explore that’s different than what the first six seasons were?
KITSIS: We always say that Emma was a character looking for her family and finding hope. I would say that Henry was the heart of the truest believer, and what we saw at the very end is he no longer believes. Henry’s loss in faith and the idea of belief is the jumping off point. The DNA of the show remains, and always will be, of hope. Each character was always looking for their happy ending, and that is no different than anyone in the real world.
HOROWITZ: One of the hardest times to have hope in anyone’s life is when you’ve lost belief or faith in something. That is a jumping off point for where we are for the next season, which is, how do you deal with questioning faith and belief and finding hope again?

This scene with adult Henry echoes the pilot, even down to Henry saying he doesn’t have a kid. Has something happened to him in terms of his memories or has he just become cynical somehow seemingly being separated from his family?  
HOROWTIZ: These are excellent questions that might be better answered—
KITSIS: —in the teaser of next year.
HOROWITZ: But they’re excellent and insightful questions.

Is the storybook that Henry charged his daughter with protecting in the Enchanted Forest the book we’ve always known, or a book with brand new stories within?
HOROWITZ: It’s another excellent question, and without getting too specific about what that book we saw in the teaser is really about, what we can say is that Henry has grown up, he has remained true to what we’ve established and he is an Author.

Let’s talk about Lucy. Who is her mother? Is it Violet?
HOROWITZ: Violet is in the montage at the end. When Henry goes to school, she’s waiting for him at the school.
KITSIS: But that being said, unfortunately like a lot of us, your first love in high school ends up not being the person you marry. You end up leaving home and moving on. It is not Violet. Who the mother is, and who Henry fell in love with, is one of the things we’re really excited about next year. In the tradition of Snow and Charming, Henry and his wife are a very much Once epic romance.

Is there a Savior in this story?
KITSIS: There could be.
HOROWITZ: There very well could be.

Can you talk at all about this new darkness coming after adult Henry that we saw in the Enchanted Forest? Is this the introduction of the new antagonist for next season?
HOROWITZ: It is. It looked pretty scary, so I don’t think it’s a new friend-tagonist. What we see in the season finale in those little snippets is, it’s a darkness that grown-up Henry has to deal with and has a big impact on what’s going on in season 7. We’re still at that we need to be slightly infuriatingly vague stage.
