In Charlotte's valentine scene, she refers to Guda as a "mirror," and man. She really do be right about that. Their core beliefs are consistent, but the way they talk to people often mirror the way they act. If you're a shitlord who troll people and schemelike crazy, they will troll you back (Ishtar, Merlin, Moriarty) if you're friendly they'll be friendly back (Francis Drake) if you're respectful and dignified and a stickler for hierarchies they'll try to be dignified back (Gilgamesh, King Hassan, Goredolf). Guda can play any role but the actor doesn't change.
