The students arrive at the station and take boats to Hogwarts. Professor McGonagall tells the first year students that they must go through the process of being sorted into their respective houses and she explains the points system and the house that wins the most points will win the house cup. Draco makes a comment about Harry Potter, which causes the other students to exclaim and Draco introduces Harry to Crabbe and Goyle. When Ron Weasley snickers at Draco, Draco insults Ron and tells Harry some wizarding families are better than others.
