Ron was already shaking his head in disbelief, staring at Harry with an expression (by now surely familiar) that clearly showed that he thought he'd lost his mind. It lightened a little when Fleur invited them for dinner - he still had an embarrassing habit of looking at his shoes whenever she came into a room - but he couldn't let this stand, he really couldn't. "That'd be great," he mumbled, with a slightly pained smile, before turning his attention right back to Harry and his ridiculous claim.

Why the hell would he show us the door? If it was him - which it wasn't, not nearly slimy enough - we'd have been ... followed, o caught up again, or something. The fact that we're sitting here now should be proof enough he had nothing to do with it."
