I like to imagine that after reconnecting with Warlock post-Armageddon‘t, Aziraphale and Crowley have made a habit out of crashing various of the Dowling‘s parties and events and confuse the heck out of everyone, much to Warlock’s delight.
After whitenessing how miserable their godson gets when having to associate with certain people, they also develop a strategy to spare him from all kinds of assholes. It‘s very simple: they channel their joined forces to aggressively put off everyone that spits intolerant nonsense.
Someone is dropping queer-phobic bullshit while sipping champagne, behaving all high and mighty?
Watch Aziraphale gush loudly and happily at the person about how his partner has just bought the loveliest dress („They are standing right over there in the black suit, you see, they are so handsome, I think I’m going to faint when I see them in lace-”) and pestering them with tmi, until the person starts to cringe and back away - and for the possibility of them still not leaving, Crowley has smuggled some laxatives into the champagne for good measure, of course.
And Warlock just stands by and tries not to snort too obviously.
