Quoting from the chapter: "The shoeless young woman was in her mid-twenties, with riotous hair and a quietly determined expression. Two things slammed into both Fred and George, though neither shared it with the other: Hermione Granger was somehow just the same and completely different than she'd been so many years ago, and she was beautiful. Beautiful in an unaffected, unintentional kind of way, beautiful in a "no I'm not, don't talk such rubbish!" manner." If that isn't beautiful imaginery, then I don't know what is.
I don't know how I missed this, but it's totally beautifully. Lovely work!
