• Hermione used her Parseltongue and the Basilisk to petrify the Half-Ghosts hiding among the students, then sent the Basilisk through the castle pipes to hunt more intruders.

• Andros revealed that Herpo sought Hufflepuff’s Golden Cup and water from Avalon’s lake mixed with blood from the Guardian’s heart.
• Andros realized that Voldemort had exposed himself by asking how to reach Avalon, and the disguised Sean transformed back into his own face.

Sean captured Andros and helped lead the cleanup after Herpo’s assault on Hogwarts and Hogsmeade. With the attackers defeated and the castle searched, Grindelwald arrived to inspect what they had gained.

• Sean refused to bargain with Andros for information about Herpo’s plans and petrified him before returning to Hogwarts.

• Grindelwald emerged from the Vanishing Cabinet and asked Sean what they had gained.

Sean realized the Returners were searching for something at Avalon, Glass Island, that could accelerate Herpo’s transformation and create a brief opportunity to confront it.

• Grindelwald told Sean that Albus had raised his wand at him and explained that the Returners’ apparent resurrection was not true resurrection.
• Grindelwald described how Herpo’s regression process produced Half-Ghosts and Half-Dead corpses, then showed Sean a Returner who had transformed into a weak, balloon-like state.
• Grindelwald suggested Herpo was undergoing the same regression and could become vulnerable before reaching the Half-Dead state needed to pass through the gate into the present world.
• Sean concluded that the Returners had come to find something that could accelerate Herpo’s process and identified Avalon, Glass Island, as the place connected to the information he had received.
• Sean and Grindelwald reasoned that Herpo’s goal of achieving godhood was to transform from a soul into a living person.

• Grindelwald and Sean argued that Herpo’s return to the real world was part of a process to achieve godhood, and Grindelwald said Pride could verify their theory.

• Sean asked Pride what stage Herpo had reached, and Pride’s guarded reply convinced Sean that he knew more than he let on.

• Sean told Hermione that the Returners’ lack of magical restrictions on revealing secrets seemed suspicious, and they considered what Herpo might be hiding.
• Daisy reported that a young student’s Patronus had helped calm Hogwarts, while Stephanie continued studying Grindelwald’s books for clues to Avalon.
• After further interrogation, Sean learned that Avalon and Glass Island referred to the same place, but the group could not locate it on their maps.
• Daisy recognized that the Returners were keeping the group hopeful with intermittent clues, and Sean concluded they were stalling for time.
• Sean reasoned that Avalon had to be close enough for Hogwarts to notice if it changed, and Stephanie identified Glastonbury as Glass Island on an ancient map.

Sean brought Hermione, Daisy, and Stephanie to Number Twelve, Grimmauld Place, where Regulus Black led them to the cave holding Voldemort’s hidden boat. After Sean retrieved the boat, Inferi surfaced in the lake and Regulus moved to protect the group.
