Minerva McGonagall is strict, exact and almost never smiles. She is also one of the few adults who defend Harry without hesitation. The books show her as she is: a stern teacher who risks everything for her students.
Who she is
She teaches Transfiguration, is deputy headmistress of Hogwarts and head of Gryffindor House. She is an Animagus and turns into a tabby cat. She is the first person from Hogwarts we meet in the books: the cat watching Privet Drive in Philosopher's Stone (ch. 1), with markings around her eyes that match her glasses. She is the one who greets the first-years when they arrive and leads them to the Sorting Hat ceremony (Philosopher's Stone, ch. 7). She believes in rules, but she knows when to break them.
Key moments
- Philosopher's Stone, ch. 9: she manages to put Harry on the Quidditch team in first year, which the rules did not allow, and gets him a Nimbus 2000.
- Goblet of Fire, ch. 22: she gathers the fourth-years and up and teaches them to dance for the Yule Ball, with the same seriousness as a Transfiguration class.
- Order of the Phoenix, ch. 20: four Stunners hit her when she tries to stop Umbridge from arresting Hagrid.
- Order of the Phoenix, ch. 29: she defends Harry's dream of becoming an Auror in front of Umbridge and promises to help him.
- Deathly Hallows, ch. 30: she duels Snape and animates the castle's suits of armor to defend Hogwarts.
Relationships
With Dumbledore, total trust. With Harry, an affection she almost never says aloud. With Snape, a cold relationship between colleagues from opposite houses. With Umbridge, open enmity. With Hagrid, mutual respect, even when he is raising dragons in secret. With the students of her house, high standards and pride: nobody in Gryffindor gets an easy compliment from her.
What almost nobody notices
In Philosopher's Stone (ch. 1), McGonagall doubts leaving the baby with the Dursleys and says so out loud: she thinks they are the worst Muggles. The facts prove her right over the next ten years.
And in Order of the Phoenix (ch. 29), her promise to help Harry become an Auror "if it's the last thing I do" is one of the few times McGonagall drops her teacher's calm to speak as a truly angry woman.
