I think Goredolf and Sieg should be friends. First of all because you know, Musik and raised by Tooles ect ect and that’s good common ground once you get past the “what do you mean we knew each other in an alternate timeline,” but also and most importantly because Sieg is one of the most normal servants around. Like yes he’s still a weirdo, no one in Chaldea is chill, but he’s normal about it. His introduction event is him apologizing for the bullshit around and being 100% down to let the Guda go if they were just not feeling like it. That’s crack to Goredolf. Goredolf is gonna steal Sieg away, make him hot chocolate specially tailored to have extra sugar in it, and then rant for half an hour about how there are too many Santas on this boat while Sieg awkwardly nods wondering how exactly he got into this situation.
