In a new interview, Adam Horowitz and Edward Kitsis tease the second half of Once Upon a Time‘s first season!

EW has a great in-depth interview with the showrunners about the second half of the season. Among other things, they talk about Graham’s death and how it’ll affect the people in Storybrooke (in an “emotional” as opposed to a “mythological” way). They also talk about the significance of Regina’s heart vault:

The reveal of the vault is a very important thing for us in terms of moving forward in the season in that we wanted to send a very clear message that Regina knows what’s going on and has some very clear intentions in Storybrooke.

On what viewers can look forward to in the upcoming batch of episodes:

What we can say is that the first batch of episode after we return in January, there are a whole lot of characters we explore — Rumple and Mr. Gold being the first. Then we also are going to be meeting Hansel and Gretel, and getting a look into the origin of the magic mirror, and meeting Belle from Beauty and the Beast. So we’re excited to see them and to see how they mash-up with our existing characters.

On romance, expect a big David/Mary Margaret episode soon! Horowitz says:

We have two people who’ve had an immediate attraction to each other, but one is just coming out of a coma and is married and the other one is Snow White and doesn’t know it. There’s a lot they have to overcome and Dr. Whale is just part of it. But one of the big stories we’re telling this season is about this true love and about how it can overcome anything. That’s one of the hopeful messages we’re trying to send with the show.

But expect David’s wife to stick around, because, “We definitely have an arc for her. We’re going to get deeper in her story in the back half of the season.”

Finally, in the words of J.K. Rowling… there will be more deaths. Horowitz cautions:

As Henry said to Emma in the pilot, the final battle will be begin. Unfortunately, with final battles, there are casualties.

We don’t like the sound of that! None the less, we know that everyone’s so excited for the show to return in January, and we are as well!
