Chapter Summaries

Harry tried to identify a mysterious map by recalling memories and asking Silvan about the Hogwarts map Fred and George had given him. Silvan secretly revealed the parchment was the Marauder's Map and saw Sirius Black alone in the Defence Against the Dark Arts office.

• Sirius burned the Dark magic book in the fireplace, then stayed behind to finish adjusting a trap for Hagrid.
• Harry asked Silvan about using a Pensieve to examine his memories for clues about the mysterious map.

• Silvan spoke the words “I solemnly swear that I am up to no good,” revealing the Marauder's Map and showing Sirius Black alone in the Defence Against the Dark Arts office.

Hermione confronted Fred and George for testing their Skiving Snackboxes on first-years, so Silvan suggested they target third-years and fifth-years instead. Fred and George eagerly adopted his ideas, and Silvan asked whether the Marauder’s Map had ever shown someone’s name incorrectly.

• Hermione stopped Fred and George from testing their sweets on first-years and threatened to tell Mrs. Weasley if they did it again.

• Silvan asked Fred and George whether the Marauder’s Map had ever displayed a name that did not match the person, and they said they had never seen it happen.

Silvan’s doubts about Animagus memories distracted him from O.W.L. revision, so he asked Professor McGonagall whether Legilimency could access memories formed while a wizard was an animal. She could not answer definitively, but suggested the question belonged in advanced Transfiguration study.

• After class, Silvan asked Professor McGonagall whether Animagi had separate animal memories and whether Legilimency could reveal them.
• Professor McGonagall said Animagus transformation involved another body and admitted she did not know whether Legilimency could access its memories; she advised Silvan to focus on his O.W.L.s.

Silvan warned McGonagall that the Sirius at Hogwarts might be an impostor because he had forgotten Silvan's cat, Tom. McGonagall decided to inform Dumbledore and forbade Silvan from investigating, leaving Silvan to avoid Sirius rather than face more fifth-year homework.

Silvan considered why someone might be impersonating Sirius and whether Harry was in danger, while keeping up with his schoolwork. At Care of Magical Creatures, Hagrid introduced the class to Mooncalves and awarded Hermione points for identifying them.

• Silvan told Ron, Harry, and Hermione that McGonagall had directed him to study the Transfiguration textbooks, but gave them no specific exam markings.

• Hagrid showed the class a row of Mooncalves, and Hermione identified them and earned ten points for Gryffindor.

Hagrid's Mooncalves made Care of Magical Creatures enjoyable, but Luna Lovegood claimed that Will-o'-the-Wisps were gathering around Silvan. After receiving an anonymous request to make a wand, Silvan wondered whether Luna's vision was connected to his wandmaking.

• An owl delivered Silvan an anonymous wandmaking request with a lock of hair and a bag of Galleons.
• Silvan decided to return the request because it lacked identifying details, then wondered whether Luna's Will-o'-the-Wisps had something to do with his wands.

Silvan suspected Luna’s descriptions of creatures reflected emotions, then visited Sirius’s office to ask for Invigoration Potion while managing to avoid alerting a Foe-Glass. He left and warned Professor McGonagall about the device, uncertain whether her wariness of Sirius would trigger it.

• Silvan considered whether Luna’s Wrackspurts and Will-o'-the-Wisps represented worries and magic.

• Silvan noticed the Foe-Glass in Sirius’s office and controlled his thoughts so it would not react to him.
• Silvan left Sirius’s office and warned Professor McGonagall that the Foe-Glass was there.

McGonagall caught Silvan breaking his promise not to seek out Sirius and assigned him a three-foot essay on the Vanishing Spell.

• Silvan woke after less than two hours when Gulu Apparated into the dormitory, then joined Harry, Ron, and Hermione for breakfast and Potions.
• Snape returned Harry’s test with a D and Neville Longbottom’s with a T, then assigned both boys remedial lessons for Saturday.
• After class, Silvan told Harry that Snape’s actions matched his earlier prediction, while Hermione argued that Snape resented Sirius and Harry was his godson.
• Ron urged Harry to complain to Sirius, but Harry worried that they would start a fight and Hermione warned that Snape might target him throughout the year.

Sirius confronted Snape over Harry’s low Potions grade, and the argument escalated into a duel in the Great Hall. McGonagall evacuated the students and sealed the doors while the professors continued fighting inside.

• Dumbledore told Silvan that Sirius had left St Mungo’s intending to travel with Harry, but arrived at Hogwarts shortly before the train and never went to the station.
