"Thank you Professor Snape for those inspiring words," Daniel said, drawing attention back to him. "Now it is up to us to explain the things professor Snape either can't or won't. First things first, Slytherin's have a rule. What happens in the common room stays in the common room. I don't think I need to explain that one. Second, if you have any issues with another student of Slytherin house you deal with it in the common room, outside of this room no matter your personal differences, stay together, stick together, and support your fellow Slytherin. No exceptions. Thirdly, if you have a problem with someone from another house, you deal with it in a Slytherin way. Professor Snape drove into you all the importance of ambition and it's our job as prefects to make sure you understand the importance of cunning. If you want to do anything to anyone in another house, either revenge or any other reason, do not under any circumstance let me or another perfect catch you."
