He had called a halt to the match three times because of an apparent threat: a helicopter passing; a flock of pigeons flying overhead; and the last time because the shadows were getting too long. Tonks had whacked Moody with her broom when she found out that they had been called in a third time for no reason other than Moody simply being grumpy because he saw the Quidditch match as a breach of vigilance.

Logically, she was aware that she would not get into major trouble for something that was simply the fault of Moody's overzealous safety precautions.

Hermione, when she glanced at him, couldn't help herself from giggling helplessly. Ron looked over at her and winked.
