Muggles' Guide to Harry Potter/Characters/Dennis Creevey

Overview
Dennis Creevey, brother of Colin Creevey, is a perpetually-excited Gryffindor who entered Hogwarts in Harry's fourth year.

Goblet of Fire
Dennis Creevey, first seen wearing Hagrid's immense moleskin coat, is Sorted into Gryffindor. On reaching the House table, he tells Colin that he had fallen into the lake and was saved by the giant squid.

When Harry Potter becomes the second Hogwarts Champion, Draco Malfoy starts distributing buttons that alternate between saying "Support Cedric Diggory, the Real Hogwarts Champion", and "Potter Stinks". As Harry heads out for an appointment with Hagrid, he sees the Creeveys, Colin and Dennis, working with one of these badges, trying to charm it to say something different. On his return, he sees that they have not been successful; all that they have managed is to make the badge say "Potter Really Stinks".

Order of the Phoenix
Both Dennis and Colin Creevey are members of Dumbledore's Army. While we don't hear much of them, it seems that Dennis is managing to master some of the more advanced charms, possibly with Colin's help, despite being only second-year.

Deathly Hallows
Dennis and Colin are seen trying to figure out how they can stay at Hogwarts and assist in the defence before the final battle, but Professor McGonagall sends them both away.

Strengths
Dennis is likely the youngest member of Dumbledore's Army; as a member, however, he has a thorough grounding in defensive magic at such a young age. He is gifted with the same boyish enthusiasm that his brother displays.

Weaknesses
Dennis is young and inexperienced. He could be a skilled wizard in the future, but when we see him, he is still in the beginning stages of magical schooling.

Relationships with Other Characters
Dennis is seen to be hanging out with his brother a lot. This shows us that he has a good relationship with his brother.

Like his brother, he also seems to idolise Harry a bit.

Analysis
Like the Weasleys, both Creevey siblings are sorted into the same house; the author shows here that she is aware magic can be taught to more than one family member. It is of note that both Colin and Dennis are Muggle-born; it is unusual that both siblings from a Muggle family would show this trait.

Dennis is in Gryffindor; he certainly shows courage by attending DA meetings. Most people of his age wouldn't dare.

Questions

 * 1) Why do you think Dennis Creevey wanted to stay for the Battle at Hogwarts?
 * 2) How did Dennis attend the first meeting of the DA, as he was a second-year and wouldn't be allowed in Hogsmeade yet?

Greater Picture
It is worth remembering that Colin dies during the Battle of Hogwarts. Dennis' young life is therefore marked by tragedy at this point.
