I’d been mentally referring to Shovel as “he” as well, so it’s good and interesting to see that challenged. I even looked up whether Quasits have genders on the Forgotten Realms wiki which says near the end “Quasits were assigned genders at the whims of whoever their masters were, whether tanar'ri or mortal” so perhaps we’re all right, or all equally wrong!
