What’s y’all’s favorite headcanon of this show?

Heyo, what are y’all’s favorite headcanon of this show?

Mine is the headcanon that Crowley had something with Leonardo Da Vinci. Could be friendship or something more.

Kudos to whoever made that, you’re awesome. But Crowley and Aziraphale have been friends for soooo long and not really doing anything about their feelings that I think it’s okay that they’ve had feelings for some humans in those years whenever they were separated.

I ship Aziracrow with all my heart but the Crowley and Leonardo da Vinci thing is just really cool, whatever way you want them.

Anyway, that’s my favorite headcanon, please let me know yours. Please and thank you and I hope you have a nice day or night😁
