Harry looked thoughtful, lips pursing for a moment. He had an idea for polyjuice. He didn't know if it would work, and he knew damn well Hermione and Ron wouldn't like it. So he kept it to himself.
He couldn't help but grin a little at Ron. "Well. . . if you'd rather walk about in women's shoes, we can let you be Bellarix, or someone else in knickers?" he suggested innocently. "I mean if you've got a taste for it now. Nothing wrong with that. We could ask Fleur to get you some skirts?"
Harry sidestepped out of smacking range, or tried to, and nodded to Hermione. "Yeah, let's go talk to Bill." He ducked out the door quickly.
