Harry Potter and the Goblet of Fire
"Why do they have to move in packs?" Harry asked Ron as a dozen or so girls walked past them, sniggering and staring at Harry. "How're you supposed to get one on their own to ask them?"
"Lasso one?" Ron suggested. "Got any idea who you're going to try?"
Harry didn't answer. He knew perfectly well whom he'd like to ask, but working up the nerve was something else ... Cho was a year older than he was; she was very pretty; she was a very good Quidditch player, and she was also very popular. (22.28-30)
"We should get a move on, you know ... ask someone. He's right. We don't want to end up with a pair of trolls."
Hermione let out a sputter of indignation.
"A pair of ... what, excuse me?"
"Well – you know," said Ron, shrugging. "I'd rather go alone than with – with Eloise Midgen, say." [...]
"Oh I see," Hermione said, bristling. "So basically, you're going to take the best-looking girl who'll have you, even if she's completely horrible?"
"Er – yeah, that sounds about right," said Ron. (22.84-91)
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 had never spotted it before.
