• Sean cast the Disillusionment Charm and left for the Common Room while Grindelwald’s figure twisted into a disguise.
• Grindelwald’s Sean challenged the four students to a bet, then summoned a surge of blue flames.

After Daisy left to consult Professor McGonagall, Hermione affirmed her trust in Sean and promised to keep helping him.

• Hugo Barbarossa arrived, passed Hermione’s assessment, and became a member of Golden Dawn.
• Hugo asked Sean whether the club would teach the Blue Flame Spell.

Sean welcomed Hugo, Ian, Patricia, and Savannah into Golden Dawn, then learned that Fabian Aiken was opposing the club because of his ties to France’s powerful Wizarding Rights Protection Association.

• Hugo explained that the association had gained influence by securing lenient punishments for wizards, including a serial killer whose crimes it concealed and recast as a fight for wizarding rights.
• Sean wondered whether Grindelwald had arranged for him to confront the association’s influence in France.

Sean learned that Fabian Aiken and his allies were helping revive blood-based divisions at Newmontgard, and decided to stop Aiken to protect the Golden Dawn and the Weasley twins. He devised a plan to ambush Aiken, who then encountered a hooded wizard in his usual herb garden.

• Savannah explained that Newmontgard's traditionally transactional but egalitarian culture was being deliberately divided, with Pure-blood and Half-blood wizards gaining advantages over Muggle-born students.
• Sean realized Grindelwald had likely tasked him with addressing the divisions, and chose to confront Fabian Aiken because Aiken was obstructing Golden Dawn and had targeted the Weasley twins.
• Sean reviewed the twins' information about Aiken's defenses, Trevor, and his Kneazle, then began planning a covert attack and considered how to shift the blame.
• Aiken told Trevor that he maintained a humble image around professors while looking down on ordinary students, and Trevor anticipated privileges after joining the Aiken Family.
• Aiken learned that few students had joined Golden Dawn, mocked Sean as a Mudblood, and entered his usual greenhouse, where he found a hooded wizard tending a plant.

Sean disguised himself as a Newmontgard student to approach Fabian Aiken, but an unexpected meeting with Ernie Macmillan gave him clues about Aiken’s Pure-blood connections. After Sean’s planted Dungbomb humiliated Aiken, Aiken entered the prefects’ lavatory, where Sean’s hidden attack left him unable to control his body.

• Sean disguised himself as an unnoticed Newmontgard fifth-year and met Fabian Aiken in the Flower Greenhouse, where Ernie Macmillan arrived unexpectedly.

• A planted Dungbomb exploded beneath Aiken, covering him in mud and dragon dung and ruining his clothes.
• Aiken ordered Trevor to bring clean clothes and guard the lavatory, then bathed and considered who might have attacked him.
• Aiken felt dizzy and lost control of his body as a strange figure emerged from the air across the pool.

Sean kidnapped Fabian Aiken from Newmontgard and hid him in his ring, but Fabian’s father traced the abduction to the school and came to suspect Sean. Old Man Aiken tried to force Sean to take Veritaserum, until a blue flame appeared in the office.

• Sean paralyzed Fabian with potion in the Prefect's Lavatory, took his protective necklace, and had Pudding carry him into the ring.

• Old Man Aiken ordered his followers to bring out Veritaserum, and a ball of blue flame ignited in the office.

• Grindelwald arrived in the office and stopped Old Man Aiken from accusing Sean without evidence.
• Grindelwald intimidated Old Man Aiken, magically made his right hand younger, and caused his left hand to disappear before letting him leave.
