"They're dead..." It took Hermione at least five more minutes to speak, though generally she processed new information quite a bit faster. By the time she spoke she was herself again, and her voice was her own even if it was decidedly shaky.
She heard that shaking, though, and then cleared her throat and swallowed once - then almost visibly pushed the thought away and stood up. "Come on," She said, waiving her wand at Ron and transfiguring his clothes back into a school uniform. "We ought to figure out how we're going to deal with that thing before everyone else goes back from Hogsmeade."
