Who are characters you’d like to see interact?

Who are two (or more) characters that haven’t interacted, but you’d like to see?

I’d kill to see Fyodor and Q interact. I also can’t think of a time where Chuuya and Atsushi have interacted, apart from WAN. Same with Chuuya and Akutagawa (they had a very brief scene together in DA, and they’ve been in the same scene without directly interacting. Any others, I don’t remember.)
