Aziraphale and Crowley are living in domestic bliss in their Cottage in the South Downs. They are happy to finally be together. Out of concern, Crowley has made Aziraphale promise to never leave the house without telling him and Aziraphale has agreed.

In the chaos of an attack against a village, Crowley hunts for a treasure he’s been seeking since the beginning. (not explicit, but Dark Crowley)
