Ron lost that calculating look as the blood drained from his face. He, out of them all (save, perhaps, for Hermione), had been the one to deal with the various losses from the war, and after, the least well. He'd fallen apart nearly as badly as Malfoy had when Hermione had disappeared. Had left the Auror department when a raid had gone badly and some intelligence that he'd gathered had been wrong, leading to the death of a junior Auror. He had blamed himself, incorrectly and unfairly, in both instances. He had only started being himself again after that second loss, had only lost that devastated look in his eyes, after he started working the joke shop, and had met Pansy. Harry wasn't sure how he'd handle this... thing with Hermione. Wasn't sure that Ron could be counted on to not do something entirely stupid. Harry glanced at Hermione, who was staring at Ron with a certain look of understanding, and Harry began to suspect at least part of what she would be making "clear."
