Though something about this whole exchange, with Vergil's worried scolding and Gil's cavalier optimism has her adding, almost offhandedly: "But I wouldn't have had to worry about that anyway, King Gilgamesh isn't the type to let someone he considers 'his' get hurt for no reason."

Yes, she noticed he called her a 'vassal' there. And no, she was not at all thinking about what she just said, as her attention is now entirely on the korok as she hands over the apple. The other two can wonder about what that remark even means if they want, or something.
