I guess I suppose the price Snow and Charming will now pay is that they are linked with one heart and if something dire happens to one, it will also happen to the other, I don’t see that there needs to be more of a price than that if it is played out correctly.
My misgivings about the way it came about aside, I do like the idea that they’re now linked with one heart. That is pretty romantic and could be put to good use, story-wise. 🙂
