Obviously Harry wasn't hurt too badly, Hermione took a moment to feel the joint a bit, making sure it didn't feel as if he'd broken his finger - though she wasn't entirely sure what that would feel like at the touch. She assumed that Harry would scream or something to let her know if it hurt too badly, though, and he didn't.
She was distracted from her rudimentary exam of Harry's hand, though, when Ron appeared, storming in to the tent. This time, Hermione had absolutely no idea what it was that had him spitting at them and furiously stomping through the tent.
"Ron?" She asked, against her better judgment, and it wondering what the hell it was he was on about this time she forgot, for a moment, to let go of Harry's hand.
