I Kinda Feel Like There Might Be Several-many Tender Scenes We Haven't Seen Yet - Tumblr Posts

Is it absolutely KNOWN that Crowley and Aziraphale didn't speak or meet at any point between the Holy Water Breakup and 1941? I see a lot of theories based on that certainty, and was curious if I'd missed where or how we came to know that for sure. S2 made it clear to me that we haven't seen all their meetings or close to it, and there's more to reveal. I feel like there definitely could be an in-between make-up scene we haven't seen yet.

It's occurred to me that "I knew you'd come through for me. You always do." would be a strange thing to say to a person you haven't seen in 80 years, especially when your last interaction was pointedly refusing a favor, spitting that you didn't need each other, and storming off.
