And then I had a discarded princess as the prince returned to the princess he had originally promised to marry. (Blame his father for the false hopes.)
Hmmm. . . . what do with a discarded princess?
There are no fairy tales I know of with such a character, but then, she's going back, and in the woods, and she could meet someone there. One of the sleeping princes? Nah, I don't like that one as well. An iron stove, perhaps. "The Iron Stove" in fact, which is considered an animal bridegroom story. Stove, animal, as long as they function as the same plot device. . . .
Of course then I have to tie off her story before the hero and heroine live happily ever after. And that of the servants. Ah, well, mash-ups are like that.
