"Welcome first years to the noble house of Slytherin" his voice was sharp and seemed to cut through the air as even Harry who was standing a decent length away from him could hear him almost perfectly "You are now part of a house which has stood for centuries and the values and traditions of said house shall be maintained by you all. There will be no exceptions. The value of ambition is key to Slytherins success, as a result I expect you to all strive towards success and I will not accept anyone who believes laziness is acceptable." His eyes seemed to flick to Ron as he said this. "This house will help anyone who can prove they deserve help, this means if you commit to improving, if you are dedicated to bettering yourself and becoming more than you are now, you will find this house to be most welcoming. You are Slytherins now, do not let yourselves down, do not fail this house and most importantly do not embarrass me." With that last warning he turned from the room and retreated back through the small door, the sound of a lock clicking ran through the common room.
