HOLY CRAP what if that ridiculous conversation between Nina and Maggie was a red herring to make us think that Crowley was too preoccupied with "Oh my gosh I have to declare my feelings right now" to think about anything else, and distract us from the fact that Crowley actually DID pick up on how stressed-out Aziraphale was and figure out whatever weirdness was going along, and actually said and did all the things he needed to do in that scene?
Today Aziraphale was reading while Crowley took a nap. Aziraphale heard Crowley shiver, so he laid a blanket out over his demon and tucked him in with a kiss to his forehead.
I've been thinking about this scene a lot and how kind Crowley is to Aziraphale, being a safe harbor for Aziraphale, something heaven was supposed to be to Crowley but never was.
