Personality

Her discipline can be severe. She rebukes James Potter and Severus Snape for their nighttime duel, escorts them directly to Dumbledore, and later silences the captive Marauders when their arguments become disruptive. 22 23 175

Although she is reluctant to compromise her principles—particularly regarding Memory Charms and releasing Gellert Grindelwald—she accepts difficult measures when survival requires them. 146 147 157 Her occasional dry humor emerges when she describes Hogwarts history as “carefully redacted.” 154

Background / History

McGonagall has served at Hogwarts for decades and identifies herself as having taught Transfiguration there for many years. She is also responsible for consulting the Admittance Book and sending Hogwarts acceptance letters to children approaching age eleven. 142

During Snape and James Potter’s conflict, she catches the pair using magic in the girls’ lavatory at night, releases James from a Petrification Curse, reprimands both students, and brings them before Dumbledore. 22 23 Her professional relationship with Dumbledore is respectful; she generally defers to his authority while taking responsibility for discipline and school administration. 23

When Dumbledore departs Hogwarts to investigate a threat, he entrusts McGonagall with instructions to act as Headmistress if he does not return. 136 After he is found unconscious in a cave, she works with Snape to bring him back to Hogwarts and assumes responsibility for his recovery, the school’s evacuation preparations, and the protection of its students. 140

To conceal Dumbledore’s incapacity, McGonagall takes Polyjuice Potion and impersonates him in public. She also works with Snape to remove the Sword of Gryffindor, the Sorting Hat, the Admittance Book, and the Acceptance Quill from Hogwarts before the Death Eaters can seize them. 142 143

After Hogwarts falls, she continues leading the exiles aboard the Founder's Boat. Initially wary of releasing Grindelwald, she ultimately accepts Snape’s argument that his assistance is necessary against Voldemort. 146 147 She remains a central organizer of the resistance until Dumbledore awakens, then briefs him on the events that occurred during his coma. 183

Relationships

• Albus Dumbledore — Long-serving colleague and Headmaster. Dumbledore entrusts her with Hogwarts during his absence; McGonagall protects him through his coma and later briefs him on the crisis. 136 140 183
• Severus Snape — Initially disciplines him alongside James Potter, but later works with him as a trusted partner in evacuations, artifact protection, resistance leadership, and the Battle of Hogwarts. 22 140 142 188
• Filius Flitwick — Fellow professor and close collaborator in Hogwarts’ and the Founder's Boat’s defenses. 31 143 154
• Gellert Grindelwald / “Mr. Green” — Deeply wary of releasing him from Nurmengard, but accepts his help against Voldemort; later coordinates with him aboard the Founder's Boat. 146 147 152
• Aberforth Dumbledore — Attempts to persuade him to evacuate Hogsmeade because of his connection to Albus, but he refuses. 142
• Elphinstone Erchott — A longtime friend and former superior from her Ministry service; McGonagall personally vouches for the reliability of his information. 186
• Alastor Moody — Fellow resistance member whose emergency Patronus message she receives; she remains concerned for him when he and the Longbottoms go missing. 143 154
