Severus gulped his wine hard down. Those two would be trouble, but he would have nothing against pranks. He only disliked pranks, if they were humiliating and were crossing the border of bullying. He really hoped that the twins would set an example of what a prank was and not go into a bullying mode. He would have a word with them, but he was sure that those two would understand it. Severus saw potential in the twins and that they would be successful in life and he wasn’t a desperate betting man.
