You go too fast for me, Crowley.
It’s obvious in the way the Aziraphale bats his eyelashes at Crowley and grumps about the fact that his pristine old jacket now has paint on it, then smiles beatifically when the demon vanishes the stain by blowing gently on his shoulder—both of them knowing full well that Aziraphale can remove the stain himself with angelic will. It’s obvious in how angry Crowley gets when Aziraphale claims he’s “nice”, and Crowley shoves him up against a wall in a standard intimidation tactic that the angel barely registers as fury. It’s obvious in the way that Crowley sits across Aziraphale with a drink every time they’re out, and simply watches the angel indulge in rich foods. It’s right there even at the start, when the Angel of the Eastern Gate shelters the Serpent of Eden from the world’s very first rainstorm with one of his wings, through they both have a perfectly functional set to themselves.
Note: This is how you show a love story. In the little moments.. In the gestures.
I don’t think my side would like that”
