Chapter Summary: “Expecto Patronum”
Key Plot Points and Events
- Professor McGonagall confirms that Su Yu is unharmed after the recent battle, while the other professors begin managing the aftermath. Madam Pomfrey examines him and finds no injuries.
- Sister Ka and Sister Fa report that all the Slytherin students are safe, and Su Yu’s defensive coordination with them has succeeded without casualties.
- Worried about Hermione and the other students involved with the Time Turner, Su Yu searches the Forbidden Forest and realizes that one of the two Hermiones is likely at Hagrid’s Hut.
- Using the Tenseigan, Su Yu locates the second Hermione, Isolde, and Buckbeak. He transports himself there and embraces the two girls in relief.
- Hermione and Isolde explain the night’s events:
- Harry, Ron, and Hermione discovered Sirius Black’s innocence and learned that Peter Pettigrew—hidden for years as Ron’s rat, Scabbers—was the real traitor.
- Lupin revealed his werewolf identity, but transformed under the full moon after failing to take his potion.
- A mysterious man in black arrived with Dementors and escaped with Pettigrew.
- Snape repeatedly protected Harry and the others, suffering serious injuries.
- Sirius was captured and scheduled for execution.
- Hermione used the Time Turner to return to the past with Harry and Isolde, rescue Buckbeak, and arrange Sirius’s escape.
- Hermione suddenly remembers that Harry has gone to the lake alone. Su Yu, Hermione, and Isolde hurry there and find him confronting the Dementors’ attack from the earlier timeline.
- Harry casts a powerful Expecto Patronum, driving away the Dementors and unknowingly becoming the “mysterious” figure he had previously believed was his father. This confirms the time-loop nature of the event.
- The group watches Snape, badly wounded but awake, carry Harry, Sirius, and Ron back toward the castle on magical stretchers.
- Hermione explains that they have roughly forty-five minutes to rescue Sirius and return to the hospital wing before Dumbledore seals it and notices their absence.
- Su Yu questions why they must proceed secretly instead of simply explaining Sirius’s innocence, leading to humorous criticism of the inefficient decisions made by Dumbledore, Voldemort, Grindelwald, and the wider magical authorities.

Significant Themes
- Sacrifice and protection: Snape, Sirius, Isolde, and Harry all risk themselves to save others.
- Time, causality, and self-fulfilling actions: Harry’s Patronus succeeds because he has already seen himself cast it, creating a closed time loop in which the future causes the past.
- Justice and wrongful persecution: Sirius’s innocence and Pettigrew’s betrayal expose the danger of relying on appearances and official judgment.
- Responsibility and intervention: Su Yu struggles with whether to observe events or interfere, ultimately choosing to protect those in danger.
- The contrast between heroism and institutional failure: The chapter criticizes the Ministry and powerful leaders for relying on secrecy, inefficient plans, and personal action instead of clear communication and organized support.
