Once Upon a Time premieres this Sunday on ABC, and now showrunner Adam Horowitz offers a teaser of how Belle’s return will affect Rumpelstiltskin’s plans.

In the season 1 finale of Once Upon a Time, Jefferson let Belle out of the mental hospital to spite Regina, and her return completely rattled Rumpelstiltskin – who had been busy carrying out his plan to return magic to Storybrooke.

Emilie de Ravin has now been promoted to a series regular, and that means we can expect a lot more Belle, and of course Rumbelle, a fan-favourite pairing! But it won’t all be love and sunshine, executive producer Adam Horowitz tells TV Guide, as her unexpected return will be a complication for Rumpel.

Horowitz explains that Gold/Rumpelstiltskin had been on such a meticulous, calculated path, and, “The wild card was Belle because he never, ever thought she was going to be coming back.”

Now Rumpel has to deal with the fact that “he has a second chance with the woman he always regretted letting go,” but this might be difficult for him to act on, as, “he is a man who has, in the past, always chosen power over love.”

Do you think that Rumpelstiltskin will be able to seize his second chance with Belle? And will she be able to see past the things he has done for selfish reasons?

Once Upon a Time comes back this Sunday at 8/7c on ABC! The premiere episode, “Broken,” sees the fairytale characters coping with the return of their memories, and Regina rejoicing in the return of magic while Emma struggles to accept the reality that Snow White and Prince Charming are her parents.
