Ducky, Jimmy, and Abby knew that y/n was Non-binary. They didn't care, they supported y/n. Y/N was born female so she wore a binder and bound her chest so she wasn't so round. Ducky knew y/n since y/n was born. Jimmy went highschool and college with y/n when y/n was a Genderfluid, (Jimmy and y/n did date in highschool). Abby knew y/n because they were secretly married. Abby didn't care if y/n didn't have a gender, and was a lesbian. To Abby that meant that she got more of y/n than others could. Vance knew as well since he hired y/n to be the Anthropologist so that Ducky didn't have to do medical examiner and anthropologist. Vance was alright with it and respected it, but he often forget to use the right pronouns. Y/N didn't mind, they were just happy he was trying. Everyone else, Gibbs, McGee, Tony, and Ziva didn't know and just by how y/n looked they thought y/n was male. Short hair, flat chest, didn't have a high voice nor a low voice, wasn't very emotional, dressed in pants and shirts never skirts or dresses. Y/N tried to tell them but failed every time. So Gibbs, Tony, Ziva, and McGee continued to call y/n male pronouns, not trying to be rude or disrespectful but not knowing y/n's gender.
