Ron Weasley

You know, Ron Weasley is really loyal and courageous. He really loves his friends. One of Ron Weasley's bravest moments was probably in Harry Potter and the Sorcerer's Stone, when they were playing wizard's chess and let the queen take him out so that Harry and Hermione could continue on to defeat Voldemort. The time he was certainly most loyal to his friends was in Harry Potter and the Prizoner of Azkaban, when he tells Sirius that if he wants to kill Harry he'll have to kill him and Hermione too. There's really no question why Ron Weasley is in Gryffindor, is there?
