Ron looked at Hermione, who to his knowledge hadn't been out of bed yet, much less standing for any length of time, to the Healer, who looked like he thought Hermione was bloody mental for even suggesting getting out of bed.
But Ron knew there was only one side to be on, and so he looked at the Healer. "She's taking a shower. I can manage that."
At least, he hoped he could without hurting her accidentally in the process. This was probably a bad idea, but his girlfriend was stubborn in her own right. "Really," he said, hoping that was enough of an argument to satisfy both the Healer and Hermione.
