Seamus Finnigan is a minor character in the Harry Potter series. He is desribed as having snady hair, freckles and being
short. He is often used as comic relief and is best known througout the series for blowing things up, his
Irish accent and is friendship with fellow Gryffindor Dean Thomas. He holds no significant plot but is recurring in other plots. In the books he asks Sir Nichols de Mimsy-Porpington how he can be nearly headless, but in the film the line is given to Hermione Granger. He explodes a feather while attempting to levitate it in a Charms lesson, a goblet of water as he attempted to turn it into rum ( and Ron Weasley claims once managed a weak
tea before an explosion) and his potion in his sixth year Potions class with Prof. Slughorn. He saved
Harry Potter from dementors in Deathly Hallows. In Order of the Phoenix he argues with
Harry about the claims of Voldemort's return, claiming he believes the Daily Propher and he refused to join Dumbledore's army, until later in the book/film when he apologies. In this sub-plot
Harry insults his mother.
