Seamus Finnigan is a Housemate to Neville, Harry & Ron; that is to say, he’s of the same House and year. His best friend is Dean Thomas, a good drawer who is currently on the run from the Muggle-borm Registration Committee. Seamus has the tendency to “overdo” spells, resulting in minor explosions. (That’s our only reference to the movies.) He’s seventeen years old, child of a witch and a Muggle. His Patronus is a fox.
