Can I speculate on what would have happened if Azi, Crowley and Muriel had remained on earth in the bookstore? I think Aziraphale would teach Muriel a couple of simple tricks and the inspired Murie would go show them to Crowley. Crowley would, of course, be indignant, but he was glad to see Azi happy. Crowley would start dressing Muriel stylishly, fearing that she would start wearing tartan clothes. Muriel would help Aziraphale put the books in their places. Crowley would do it too, but when no one was looking. The Demon would be just as angry because Angel often explains things to Muriel and would ask for attention for himself. Although I also think that Azi spent more time on Crowley, it’s just that for the Demon it looks like “a little time with others is a lot, but a lot of time with me is not enough.” I want them to be a nice married couple, I want to cry..
