I'll be honest, the evil editor is the one thing I absolutely dislike about this manga. It just reeks of "anyone who criticises my work is a trolling hater", which is a dumb fantasy. Editors aren't like that, he's just doing his job.
And once more, I think this picture is even funnier if you remember they don't have photography in their world. Edelgard commissioned someone to draw her wife eating bread.
