I would not overthink Zelena in Storybrooke she has her slippers to take her where ever she wants.

But if Regina, Snow and David cast the curse they will need to make a sacrifice or who ever did needs to. Aurora is a possibility for sure, but she would need to kill her baby that would be awful, or maybe she transfered her baby to Snow and she will have twins.
