Chapter Summaries

Nelson found himself inside a room packed with black boxes after Pythia vanished, while the battle against Barry’s Obscurus continued outside. Tom Riddle drew the Obscurus’s attention as Alexander searched through its body, and Tina Scamander found two injured wizards linked to the battle.

• Nelson examined the black boxes, suspected Pythia was his future self, and heard a lock click nearby.
• Andre explained that Nelson would likely use Patronus-based magic against Barry’s Obscurus before Gioconda knocked him unconscious and treated him.
• Tina Scamander spotted Zweig, then found two injured wizards he had been treating and called for help.
• Tom Riddle addressed the Obscurus, which turned toward him and became distracted by Barry’s memories.
• Alexander struck the Obscurus and searched its body with beams of light while Tom watched.

As the Obscurus invaded Alexander from within, Tom sent Gioconda to protect Nelson and used blood-tracing to follow Barry Dippet. Meanwhile, a group discussing Moody's unconscious state was interrupted by an objection to their plan to examine him and another person by force.

• The Obscurus climbed into Alexander through gaps in its armor, while Mayflies inside the giant formed an army to fight the invading fragments.
• As the battle turned into a race to find Barry before the Obscurus reached Nelson, Tom sent Gioconda to Alexander's head, where her snakes began swallowing the slime.
• Tom found Barry Dippet's shadow in an alley, used blood-tracing to follow its connection to the Obscurus, and sent a python after the trail.
• A group considered using Moody's eye to see his memories and proposed examining another person if that failed.
• Someone objected, warning that Dumbledore's student would arrive soon and that Dumbledore would not approve.

Dumbledore arrived as the International Confederation of Wizards argued over how to respond to the crisis in Berlin, while a Voodoo wizard was ordered to force memories from the injured Nina Kant. An explosion struck the city at four fifteen, and Dumbledore rushed to the ward where Moody and Nina were being held.

• An old wizard ordered the Voodoo wizard to use Legilimency on Nina Kant, despite the risk to her life, and the ward was cleared for the ritual.

• The Confederation representatives argued over sending Aurors into the danger zone and considered contacting Grindelwald at Nurmengard for help.
• Dumbledore arrived and hurried past the meeting to search for Moody, while Tina followed him upstairs.
• An explosion rocked central Berlin at four fifteen, and Dumbledore blasted apart the ward door after Tina blocked the guard’s spell.

Dumbledore found a Voodoo wizard performing a ritual on Moody and Nina, and violently stopped him after seeing the damage done to his student. He treated Moody’s wounds, then discovered that Nina had lost both eyes as the other wizards arrived and defended their actions in the name of peace.

• Dumbledore and Tina entered the ward and found Moody mutilated, Nina unconscious, and a Voodoo wizard holding a bloody dagger beside them.
• The Voodoo wizard claimed Moody had endured the ritual willingly and that his eye preserved visions from the past.
• Dumbledore crushed the dagger with his magic, broke the Voodoo wizard’s cane, and hurled him into a grandfather clock.
• Tina rushed to help the injured while Dumbledore examined Moody’s extracted eye and saw that the wizard had preserved its residual visions in a bottle.
• Dumbledore cleaned Moody’s wound and sealed it with ice as the gathered wizards’ elder argued that their actions served peace and pointed to Nina’s sacrifice.
• Dumbledore recognized Nina and saw that both of her eyes had been destroyed.

Dumbledore reflected on the regrets that had shaped his choices as he confronted the wizards who had harmed Nina and chose to enter Berlin himself. Meanwhile, Tom found Barry Dippet inside a ruined house and began to confront him.

• Dumbledore saw Nina’s injuries and recalled the moment he had let Grindelwald fall in Paris to save Tom, leaving another regret behind.
• Dumbledore remembered how he had restrained Nelson in the past, then decided not to interfere with Nelson’s war in Berlin.
• Dumbledore opened a passage through the wall around Berlin and challenged the other wizards to follow him into the city.
• The wizards hesitated while Tina cared for Nina, and one mocked them for having taken three eyeballs.
• Tom found a small, blackened boy named Barry Dippet in a ruined house, pulled a thin black thread from his head, and raised his wand to confront him.

Tom dismantled the magical balance binding Barry’s memories and discovered that Barry’s missing heart was the abused child hidden within his Obscurus. Zweig explained Dippet’s plan and asked Tom to hand Barry over for treatment, while the battle continued and Tom challenged Gioconda’s belief that Nelson could not wake himself.

• Tom extracted a memory of Barry being refused admission to Hogwarts by Dippet and stored it in a crystal vial.
• Dumbledore entered Berlin’s city center as Tom continued breaking the runes that bound Barry’s memories.

• Zweig asked Tom to hand Barry over so he could try to cure him.
• As the Obscurus pressed its attack and Gioconda worried Nelson could not use the Patronus, Tom replied that he could.

Tom tried to persuade Gioconda to escape, but she chose to remain with the Muggles she had brought to Berlin. Nelson awakened and joined the fight, cutting the Obscurus in half and blasting another hole through the Berlin Wall.

• Gioconda showed Tom the Deathly Hallows-inspired Locket and explained why she had chosen to stand with the Muggles, whom Nelson had inspired.
• Tom summoned a Giant Python to offer Gioconda a way to evacuate people, but she refused and insisted on staying to fight.
• Inside the maze of Black Boxes, Nelson climbed above the shifting boxes and leapt toward a newly opened story.
• Tom used a small snake to bite Nelson awake, and Nelson confronted Gioconda as the Obscurus surged back onto the deck.
• Nelson assembled Mayfly into a sword and cleaved the Obscurus in two, leaving a deep slash through Berlin.
• Nelson transformed Mayfly into a shoulder-mounted device and fired a silver-white beam through the Obscurus and the Berlin Wall.

Nelson returned to Berlin and used his magic to awaken Alexander as the Obscurus tore the city apart. He opened a path to the long street, where Muggles and wizards were resisting the monsters together, and prepared to face the world’s questions.

• Nelson’s earlier message to Zweig revealed that he had asked him to leave Barry a sight in the Department of Mysteries, where Barry could find Armando Dippet’s final words.
• Zweig watched Barry disappear and trusted him to fight for his own life as the boy’s memories drifted toward the Obscurus.
• Nelson guided Alexander’s transformation as the Obscurus split in two, and the awakened system sent silver Mayflies to fill the giant’s exposed frame.
• Nelson transfigured the buildings aside to reveal Muggles and wizards fighting the life-devouring shadows on the long street, while the International Confederation of Wizards debated whether to stop him.
• Nelson thanked Gioconda for her choices and told her that humanity could change its fate, then warned that they would soon face the world’s questions.

Alexander transformed into a colossal Mayfly-built warrior and trapped the Obscurus in a barrage of light. As the International Confederation of Wizards debated Nelson Williams’s devices and Muggles’ use of magic, its leaders decided to exploit the crisis and move against him.

• At Nelson’s command, Alexander approached the Obscurus and sealed it in a cage of scorching beams and spears.
• Dumbledore recognized that Alexander’s body was assembled from simple Mayflies whose coordinated work created the illusion of individually adaptable machines.
• The International Confederation of Wizards discovered that Nelson’s registered Missionary device had enabled Muggles to use stored spells, and its members argued over who had concealed its spread.

Johnny carried the gravely wounded Joseph out of the forest as the Wizarding Government’s Aurors overwhelmed the defenders and the forest burned. After leaving the rescued Muggles hidden in a farmhouse, the two headed toward Berlin, where signals from their allies drew the Aurors away before a gigantic ice penguin froze the battlefield.

• Johnny carried Joseph and the retreating survivors to a farmhouse, where he counted the Wizards who had stayed behind to cover their escape.
• Johnny prepared to leave with Joseph, and Joseph insisted on going despite his serious injuries.
• Johnny sealed the farmhouse around the Muggles and left with Joseph, telling them to stay quiet and draw no attention.
• As Aurors pursued captives through the air, Johnny hid with Joseph beneath the Invisibility Cloak and saw allies signal that it was safe.
• Penguin signals appeared in every direction, splitting the Aurors’ pursuit, while a gigantic ice Emperor Penguin formed over the forest and froze the battle.

Ogden survived Penguin’s attack on the Aurors and learned that the operation in Prussia had misrepresented Muggle refugees and resistance fighters as dangerous enemies. After Penguin froze himself and the remaining Aurors, Ogden took his camera and asked the ice-encased wizard his name.

• Ogden’s protective pendant shielded him from Penguin’s spell, leaving him as the only Auror still standing amid the frozen group.
• Penguin accused the Aurors of attacking innocent Muggles, while Ogden recalled how the International Confederation of Wizards had ordered them to hunt the fleeing people after falsely branding them Second Salemers.
• Ogden remembered seeing Penguin address hidden refugees and threaten the Aurors with explosives, then distract them while the fugitives escaped.
• Penguin explained that he had acted to protect his friends and that the Aurors had been misled about what was happening in Berlin.
• Penguin froze over completely, and Ogden removed his camera, took a photograph, and asked him his name.

Ogden failed to break through the ice sealing the forest while Aurors in Berlin prepared to attack Nelson Williams, unaware that their strike force had gone to the wrong stronghold. Alexander’s gaze turned toward the city as Joseph chose to leave Johnny and join the coming battle.

• Ogden photographed Penguin, found the image showed him among hiking penguins, and gave up trying to break the Ice Wall.
• An old wizard briefed the International Confederation of Wizards’ Aurors on Nelson Williams’s trap against the Prussian dark wizards and urged them to capture him.

• Martha showed Moaning Myrtle a copy of The Quibbler depicting Nelson confronting the Aurors and introducing himself as Nelson Wiltening Williams, “Just one man.”

Nelson Wiltening Williams confronted the Aurors and the International Confederation of Wizards in Berlin, survived their attack by dispersing into water vapor, and broadcast a call for people to join his cause.

As Nelson Wiltening Williams’s broadcast reached London, Tom Riddle Sr. reflected on how magic had ruined his life and feared it had cursed his children too. He answered Nelson’s call and received a mechanical Wand from a falling Meteor, leaving him able to perform magic as the city watched a shower of lights descend.

• Tom Riddle Sr. listened to Nelson Wiltening Williams’s broadcast from Christian’s hospital room and remembered his painful history with Merope Gaunt, Tom, and Christian.

• Nelson charged through the Aurors' barriers with a sword formed from Mayfly fragments and struck the old wizard, while an Auror was caught between them.
• The old wizard's spell hit the intervening Auror, and Nelson's sword pierced both men before Nelson vanished in white smoke; the old wizard destroyed the sword fragment but lost the use of his wand arm.
• Tom used an Auror he controlled to seize the wounded old wizard and urged the crowd to question whether their allies harbored hidden intentions.
• Tom's voice and reflected metal fragments sowed panic among the Aurors, breaking their formation and causing some to be struck by their companions' spells.
• Tom claimed the spell had only imitated his voice, then taunted the Aurors for believing that they were controlled and for leaving their elected leader wounded on the ground.

Tom undermined the International Confederation of Wizards’ Aurors by turning their suspicion against one another and revealing what they had been sent to defend. As the force fractured and the Water Screens broadcast the scene worldwide, Dumbledore left the rooftop and Grindelwald arrived with the injured Barry, saying a prophecy in Nelson’s desk had drawn his attention.

• Tom told the Aurors that suspicion made it impossible to know who was under another person’s influence, then challenged them to question their orders and loyalties.
