If you've never heard Børns' song "Holy Ghost", that's been one of my go-to Crowley & Aziraphale songs for years. Very lovesick and sexy and spiritual.
This was originally going to be a lot more explicit, but then I did the wings and I was like, you know what... I think it's enough. Aziraphale's face says it, I hope.
I imagine that once they can finally be together, they're gonna have moments where it just hits them in the soul that they've been waiting for this for six thousand years.
