you pose a very good point, nonnie. gris, as a supporter, is always there to help and be useful in and out of cleaner duties. if you told gris you weren't feeling well, i think he'd immediately make it a priority to assure you get proper care and treatment. he'd check your temperature with his big palm against your forehead, make sure you were eating and drinking plenty of water, monitoring your medicine doses, etc. honestly, i can see him almost mother henning you due to his strong sense of looking out for others
but i can also make an argument that any of the givers would also be excellent candidates to take care of you when you're sick. after all, they have the natural innate ability to cherish their jinkis, and i do believe that could bleed into caring for another person once they're close enough to them
