I think in the end, Mr. Gold and Regina will both relent. The fact that this is the sneak peek that was released means that this is probably from the beginning of the episode. So, something eventually deactivates the portal. Besides, Mr. Gold still needs Emma for that favor. He can’t leave Storybrooke and he’s still searching for Baelfire.
And if I’m not mistaken, Belle is scheduled to be in this episode as well. So, I have a feeling she’ll factor into Mr. Gold’s actions in this episode.
