Emma has to make a sacrifice much like Regina did in 3A and has to leave Storybrooke and everyone else behind in order to break the curse. Henry leaving with Zelena and her child breaks Regina's heart and she starts an ever so slow turn back to the darkside (no thanks to Rumple) since she no longer has Henry or Robin to continually pull her in the right direction (Regina took some of the Evil Queen's hate back so I would exploit that as well as the hole the original dark curse created but was told could NEVER be filled). Henry returns a few years later to find Storybrooke is no longer the town of hope like it once was but instead is a town ruled in terror by Rumple (upset that Belle and Gideon couldn't find it in their hearts to forgive him so they left) and to an extent a conflicted Evil Queen. Zelena, who still feels powerless to do anything, concots a way to gain her powers back using her old pendant but wearing her old pendant also returns some of her wickedness. The season would revolve around Henry trying to get Regina to realize the error of her ways (while fighting off both Rumple and Zelena) while also trying to figure out if there's a way to bring Emma back (they finally figure it out with Emma returning in the series finale). I would have it be between 14-16 episodes and then call the series done.
