Dean Thomas is a Gryffindor in Harry's year and one of his dormitory mates, a sociable, soccer-loving boy whose West Ham poster marks him as a link between the Muggle and wizarding worlds. Across his first four years at Hogwarts he stays in the background of Gryffindor life, a steady and loyal classmate through the Chamber of Secrets crisis, the Sirius Black scare, and the Triwizard Tournament. His candid reactions, quick humor, and readiness to help, such as offering to forge a Hogsmeade permission slip, make him a familiar part of the house's camaraderie. As the world around him grows darker, Dean comes across as an ordinary student still finding his footing in a strange and dangerous world.
