NPCS constantly speak to me as "The Lamb" when I have the Goat skin/play equipped and it often takes me out of the story (a little funny to read though.) I don't mind NPCS referring to the Lamb or things like the sermon having only Lamb related bubbles, I think those are great! But when an NPC is talking to Goat they should call them a goat!
I think there should be certain special dialogue about Goat other than just replacing Lamb's name in text with Goat's. Clauneck could call them "The Lamb's acolyte," Shamura could tell Goat that Lamb will betray them too. Powerful beings could recognize Goat as a demon, Mushroomos/Lighthouse followers could comment on how they've never seen a creature like Goat before or think they're from distant lands, etc etc
I've seen certain cutscenes/battles turn me back into Lamb so that could apply if there's other scenes that only apply to Lamb.
