Set AU-ishly somewhere in Season 4 (no demon blood addictions, Jimmy is gone). Castiel's vessel has started to develop basic needs. His libido seems to think it's a fifteen year old's. Sam helps him control it.
Sam and Dean have always been oddities among the dragonriders; the youngest man to Impress a Bronze dragon in a hundred years and a boy who turned his back on the riders to become a dragon healer instead. But when fate steps in and chooses a far different path for Sam, the brothers and all the Weyrs of Pern will have to come to terms with much greater changes in their traditions.
