It was Hermione.
But she didn’t look like Hermione at all. She had done something with her hair; it was no longer bushy but sleek and shiny, and twisted up into an elegant knot at the back of her head. She was wearing robes made of a floaty, periwinkle-blue material, and she was holding herself differently, somehow - or maybe it was merely the absence of the twenty or so books she usually had slung over her back. She was also smiling - rather nervously, it was true - but the reduction in the size of her front teeth was more noticeable than ever; Harry couldn’t understand how he hadn’t spotted it before.
"Hi, Harry!" she said. "Hi, Parvati!"
Parvati was gazing at Hermione in unflattering disbelief. She wasn’t the only one either; when the doors to the Great Hall opened, Krum’s fan club from the library stalked past, throwing Hermione looks of deepest loathing. Pansy Parkinson gaped at her as she walked by with Malfoy, and even he didn’t seem to be able to find an insult to throw at her.
