A lead on the Horcruxes. Hermione's stomach dropped into her feet, both shocked and excited. For once, she couldn't even speak for several moments as she studied her friend's face, trying to be certain that he was serious. She knew Ron as well as she knew anyone in the world. He meant what he said. She forced herself to breathe, having forgotten a moment or two, and then jumped again as she heard Harry's voice.
"Oh... Harry. Y-yes... yes, it's him. It's fine. Tell... Tell Harry what you told me, Ron, but... but explain. Go on. What... How?" Wow, she really was speechless. The boys might want to celebrate that occasion, considering it was one of the rare moments in her entire life.
