Joke
It had gone beyond a joke. Ron had over stepped too many lines for him not to get away with the things he said. While the first few times he'd imitated Krum on land had been funny, now he was just being cruel.
George sat on the other side of the common room, watching her as she tried to focus on her homework, hopelessly ignoring the rude comments Ron was saying slightly louder than he should be. He understood why Ron was trying to make jokes about Viktor Krum- he was a rival. He had set himself up with Hermione as her Yule Ball partner and the incident in the lake was well, not what anyone had been expecting really. He got Ron's frustration and anger that some idiot from another country with much more wealth and talent than him had just stepped on the scene and taken her into his arms. He was angry about that too. He fancied Hermione as much as any of the guys with eyes did at Hogwarts. Hermione was a very pretty and intelligent girl. She was a dream of any boy. But there was no need to be rude about her and Krum.
"Ron, shut up. We've heard the joke before. Just sit there and do your homework." Ron looked up at him, taken aback by the tone in his brother's voice. Hermione just smiled at him across the room, grateful he had put an end to the joke.
