The companion piece. (They spend a few interesting months developing an antidote for the spell that keeps princess Pietra, well, a princess instead of prince Pietro. It doesn't work, not for a whole day and he should feel bad because Peter's been wanting to have his old body back for years, for decades, but then the kid looks at him beneath longer than usual eyelashes, soft skin hidden behind lace bows and pastel silks and Tony's gone.)
(Peter doesn't really mind after a while, embraces it actually, overjoyed with the knowledge that he can melt a certain king's heart no matter the body that holds Tony at night. The man loves him for him, not because of what's between Peter's legs and that's enough to melt the prince's heart too.
Although it is nice to tease his lover with two bodies, he won't lie about that.)
