"Do you remember your way back to Gryffindor?" she asked. "I could get the house elves to fetch you some food if you wanted to clean up." She was conscious of the fact that Arya wouldn't appreciate it if she hovered, but she was good at taking care of practical matters, if only by being unwaveringly firm until they got done.
