@pastelolivee I'm not sure if I really have any specific hints to be honest -- It's tricky, especially if you want the relationship to not seem forced. In the show, he doesn't seem to have any capacity for emotion/sentiment, the closest he gets is obsession or attraction with Sherlock and Eurus. But I mostly got it by thinking through a bit myself, and reading other fics helped to. There's one on Ao3 by WIckedlyEmma that I think does a fantastic job of portraying Moriarty, and another one called The Great Game by N0vablue. Both do a really good job of portraying his unpredictability, which I feel like I've missed a bit. Overall, if you're trying to write Moriarty, I would suggest looking at other fics and taking the bits and pieces you think are best. It is your fic, and therefore sort of your character -- If he ends up technically a little out of character, then that just makes your fic more unique compared to other peoples'! Hope this helps, and thanks for all your comments and votes on my fic!
