Work Text:
donatello knows what it's like to constantly have to look our for your own body, and the inconveniences that comes with staying vigilant, or in his case, having to work around his soft shell
it didn't take him long to notice your soft winces or sharp breaths when you got pain or discomfort, and it didnt take him long to start worrying, desperately at that
everytime you had trouble standing or kneeling, he was there to offer a hand, whether that be pulling you up gently, helping you down the stairs, or being condescending towards anyone who gives you shit for it (as with the rest of the brothers, of course)
it'd hurt him. sometimes he'd stay up, eyes wide open, trying to put his brain together and think of something to help you, for gods sake. he'd probably evaporate on the spot if anything happened to you
"thats what i'm here for, what i can do." he thought to himself, his brothers snored next door, and while he held you, finally asleep after a bad night. "its what i want to do. i want them happy.. it makes me happy."
