Harry rolled his eyes at Ron, but didn't bother arguing the case for Snape-sighting again. He knew what he saw. He'd just have to try to figure out why he'd seen it without them, if they wanted to think it'd been a trick. He knew what polyjuice wearing off looked like.
He couldn't help but smile at the mouse Luna had liberated. "Luna made friends with him while we were all held," he explained. It was a bit daft. But then, it was Luna. She'd made the best of a bad situation. It was something Harry admired her for a bit, really.
He took the set of clothes that were for him, setting them aside for the moment in favor of food. Food had a higher priority than clean, non-tattered clothes in Harry's mind. "Yeah, this is fine, thanks," he told Fleur quickly, starting to pile an improbable amount of meat and things onto bread. "They should know about Griphook too. And the bit about the goblins at Gringotts," he added after Hermione asked him about having told the Order.
