Daryl and Johnson are always arguing when they are drunk. Today they are steaming drunk and Daryl dares Johnson to stab Kristof, who both of them detest but have always been fearful of. Kristof is involved in major criminal activity and runs an organized crime group. Daryl, knowing that it will cause Kristof to fall into a rage, calls his mum a very rude word. Kristof responds in the way both Daryl and Johnson thought he would by trying to hit Johnson. Johnson responds by stabbing Kristof and claiming that he did so in self-defence. He states that although he thinks intended serious harm, he can't really remember much because he was intoxicated and only responded in the way he did because he was scared of what Kristof might do.
