Gawain and Ragnelle

They retire to the wedding chamber and Dame Ragnelle turns into a beautiful woman.
And she explains "Oh, BTW, I was cursed by that same Fae to be ugly, but I'm now at least partially uncursed since a good knight married me. I can only be beautiful for half the day, either during the sunlit hours or at night. Choose for me, do you want a beautiful woman at night all to yourself and a hag to show to your friends? Or a trophy for your friends and a hag to share meals with?"
And Gawain, secure in his manliness goes "Babe, what I want doesn't matter. You choose. Like you said to my king, all women want is the right to choose their own fate. Besides, screw other opinions."
Then, Dame Ragnelle smiles and says, "I choose both." And the spell is broken and she's beautiful all the time. And Gawain goes "Oh....SWEET! This learning lessons things rocks."
