Ernie Macmillan is a Hufflepuff student in Harry Potter's year. He is described as "a stout boy" and has "pudgy hands".
Role in the BooksEdit
Ernie Macmillan is apparently one of the students who is helped after the grand chaos of the Duelling Club by Professor Lockhart: "Up you get, Macmillan..."
Identified only as Ernie, he is apparently the leader of the group of Hufflepuffs discussing Justin Finch-Fletchley's decision to remain in hiding when Harry Potter is thought to be the Heir of Slytherin, in The Duelling Club. He more or less acts as spokesman of the group when Harry confronts them – as a scion of an old wizarding family, he feels that the Heir of Slytherin would not attack him – and later accuses Harry of petrifying Justin when Justin is found in the hallway. (Professor McGonagall addresses him here as "Macmillan", giving us his last name.) Ernie is then given the task of wafting the petrified Nearly Headless Nick up to the Hospital Wing with a large fan.
Later, when Hermione Granger is Petrified, Ernie makes a point of apologizing to Harry for having thought him the Heir of Slytherin. Ernie feels that, Muggle-born or not, Hermione would not be a victim if Harry had anything to do with it.
Harry sees Ernie in the campground at the Quidditch World Cup.
He also harassed Harry by wearing a Support Cedric Diggory Badge/Potter Stinks Badge when Harry's name came out of the Goblet of Fire and stopped speaking to him because he thought that Harry put his name in for further glory. However, during the last task, Cedric Diggory was murdered by Lord Voldemort and Ernie became nicer to Harry. He also was one of the few students that believed that Voldemort was back.
When Harry, Ron and Hermione are on the way to Herbology, Ernie runs up to them and tells Harry out loud, that he fully believes Harry and Dumbledore's claims about how Voldemort has returned. It cheers Harry to know that some students who are not weird believe him – previously, only Luna, apart from Harry's friends, had expressed belief in his and Dumbledore's statements.
Ernie is one of the original members of the Defence Association, or as it becomes known, Dumbledore's Army. He shows up at the initial meeting in the Hog's Head, but is initially reluctant to sign his name to the paper that Hermione is passing around. "After all, I am a prefect," he says, meaning, presumably, that he has to set a good example. Hermione points out that she's not going to leave this bit of parchment lying around, after which he signs, though still with some show of reluctance.
As a member of Dumbledore's Army, his work seems to be decent but not worthy of too much comment. He is, apparently, able to conjure a Patronus before the group is betrayed and broken up.
The day after Umbridge is appointed Headmistress of Hogwarts, he tells Hermione, Ron and Harry that Dumbledore will be back soon and Hermione starts to insult Umbridge, but Draco Malfoy comes around and says that he's "afraid" he'll have to dock Gryffindor and Hufflepuff House a few points. Ernie, then says that only professors are permitted to dock House Points. But Malfoy explains that since he is a member of the newly founded Inquisatorial Squad, he is permitted to dock points from anyone he wants. So he docks Hufflepuff House 10 house points for "contradicting" Malfoy's ability to dock house points, which angered Ernie.
As the OWL exams approach, Ernie takes up the disquieting habit of asking everyone how much studying they are doing, and proudly saying that he is averaging eight hours a day.
Ernie is also one of the six members of Dumbledore's Army who see Draco Malfoy attempting to jinx Harry on the Hogwarts Express, and promptly return fire, leaving Draco, Crabbe, and Goyle looking like gigantic slugs squeezed into Hogwarts robes, which Ernie takes pride in doing for revenge against the 10 points Malfoy docked from Hufflepuff.
Ernie first appears in Professor Slughorn's NEWT-level Potions class, where it is revealed that he is the only Hufflepuff in their year who has managed to get in to it. When the trio come in he says hi to them and later sits at their table.
Later in the year, Albus Dumbledore is murdered by Severus Snape. Ernie asks Harry about what is going on, but he recieves no reply. However, he learns that Dumbledore has been killed and he likely attended Dumbledore's funeral.
Ernie is one of the group of Dumbledore's Army alumni who have retreated into the Room of Requirement, thus being able to stay on at the school and keep a form of guerrilla warfare going on against the Dark curriculum. With the others, he greets Harry's arrival with loud cheers and demands to know when they will be taking Hogwarts back.
Ernie takes part in the battle for Hogwarts. When Harry has to get to the Shrieking Shack, he finds his way to the Whomping Willow blocked by Dementors. He is unable to produce much of a Patronus himself, but Ernie, Luna Lovegood, and Seamus Finnigan arrive with their Patronuses and clear his way. The passage of a twenty-foot-tall giant separates them, and Harry, Ron, and Hermione proceed to the Shrieking Shack through the tunnel.
Ernie is generally friendly, loyal to his fellow Hufflepuffs and takes his prefect responsibilities seriously.
Ernie tends to be pompous around his fellow students and sycophantical around teachers. He likes to brag about how seriously he takes his studies.
Relationships with Other CharactersEdit
Ernie and Hannah Abbott both become prefects in Harry Potter and the Order of the Phoenix, Harry's fifth year. It is never made clear whether there is any romantic entanglement between them, though they do seem to be seen together a lot. From the Black family tree created by the author, we can see that his family is distantly related to the Black and Prewett families.
