Aziraphale's hand touches Crowley's cheek, and Crowley looks down at the angel desperately. He loves Aziraphale. He has always loved Aziraphale. That has to be for something. They can't be like this for nothing.

He turns his head just a little to press a kiss to the angel's palm.

He lowers his hand down to Aziraphale's waist. They're on their own side, but why would they need a side if the Almighty would just fight for what she created? She created them, she gave them the gift of love. They deserve to live with it.
