Harry Potter and the Prisoner of Azkaban

Ron obviously realized that he’d gotten Harry into trouble, because he hadn’t called again.

Their Seeker, Cho Chang, was the only girl on their team. She was shorter than Harry by about a head, and Harry couldn’t help noticing, nervous as he was, that she was extremely pretty. She smiled at Harry as the teams faced each other behind their captains, and he felt a slight lurch in the region of his stomach that he didn’t think had anything to do with nerves.

He and Ron simply sat admiring it from every angle until the portrait hole opened, and Hermione came in, accompanied by Professor McGonagall.
Though Professor McGonagall was head of Gryffindor House, Harry had seen her in the common room only once before, and that had been to make a very grave announcement. He and Ron stared at her, both holding the Firebolt. Hermione walked around them, sat down, picked up the nearest book, and hid her face behind it.
“So that’s it, is it?” said Professor McGonagall beadily, walking over to the fireside and staring at the Firebolt. “Miss Granger has just informed me that you have been sent a broomstick, Potter.”

“Naturally,” said Madam Rosmerta, with a small laugh. “Never saw one without the other, did you? The number of times I had them in here — ooh, they used to make me laugh. Quite the double act, Sirius Black and James Potter!”
