[Health and happiness is something that Santa can handle, for Manning and any existing and future children they may bear. The wish slips over them as an invisible veil, shining and golden. They will not fall easily to injury, and will prove particularly resilient against illness.
It's the second bit that this Santa feels no small amount of anxiety over, even as he wills it into the universe's hands. Should anything ever happen to Iris, her desires will be remembered. He sends no note, but a bouquet of pointsettia appear on her doorstep.]
