Bloody hell. Ron had no idea what was going on in Hermione's mind, but it wasn't good. Shifting as close as he could over to her side of the bed without actually touching her, he brought a hand up to place gently on her shoulder. Only the faintest touch really, even though he knew it wasn't bruised. He absolutely hated the fact that he couldn't do anything right now.
He let her cry in silence though, knowing that she couldn't answer any questions he had, and there weren't really words he could find when he had no idea what was going on.
