Nah, he wouldn't be very. His canon friends drink around him at parties too. It's just something he eyes a little like the old man he is and then ignores, lmao. ... ... honestly... god I'll have to see. He misses his master/father figure so much at this point of canon and it's been so long since he died that he might... actually... get a kind of conflicted nostalgia, thinking about him. LMDSKjs. "god that bastard loved his wine."

SINGING... oh no that's cute. no one's sang for him since his other, first father figure when he was little, and that's a whole ass complicated tragic can of worms. (don't ask, he has multiple dead father figures and no actual parents... they sold him, so he was told...) it doesn't even matter if it's terrible, he'd be charmed.
