   Summary

   When Crowley goes into heat, he sequesters himself from the rest of his merlotl maelstrom like usual, picking one of the good caverns with lots of dipping pools to make his nest. The cavern and pools are empty when he falls into a restless sleep, but when Crowley is startled awake he is no longer alone, and the scent of alpha fills the air.
