I'd love to know what other characters in other fandoms Landa should meet.

I ship Heydrich with so many people it's not even funny. He's a perfect match for Hans Hotter, the greatest Wotan of all time. Hotter always made fun of the Nazis, so it's easy to see him being called into see Heydrich and then subsequently bending Heydrich over his desk for giving up music for all his SS shenanigans.

Oh, please do Hellstrom, I'd love to see what you say about him!
