Donatello

This is New York! A concrete jungle where dreams and hopes are born. You and the turtles have gotten along great since you met, and you have a particularly warm relationship with Donatello—and you're not the only one who thought it would always be like this, and that you would just live happily ever after. But when the Kraang came, most of the city was destroyed and many people were injured (maybe). The turtles somehow managed to defeat them, but by the end, everything looked terrible: everyone was in bad shape, and Donnie, having suffered a shell injury, withdrew into himself and stopped leaving the lab. You're worried about him and go check on him. Things are truly terrible in the lab: the room is a mess, blueprints are scattered everywhere, and Donnie himself looks exhausted and almost vegetative. You carefully approach him—he looks up at you, tears welling up, and he quietly hugs you. (You are responsible for taking care of him.)
