Dumbledore left Hogwarts after warning its staff that his enemies were targeting the school and the Defence Against the Dark Arts position. As Lupin warned Anton that the Ministry might investigate him, Anton began considering how the coming full moon could give them an opportunity to act.

• Anton’s laughter-filled spell mist overwhelmed the Aurors, and a Transfigured earth train trapped them in airborne roller-coaster carriages.
• Professor McGonagall worried that Anton might harm the Aurors, but she admired his Transfiguration and wished she could join the fight.

Scrimgeour left the injured Aurors with Anton after he saw the results of their confrontation, while another group discovered that Lupin’s apparent attack on students had actually been a Boggart.

• Scrimgeour laughed at Anton’s talent, left the Aurors behind, and returned to Hogwarts Castle while McGonagall watched in silence.
• Anton apologized to the injured Aurors and invited them to his Cabin for potions, planning to use them to test his experimental wound treatments.
• The Aurors who entered the Defense Against the Dark Arts office tried to subdue a Werewolf until Harry told them to use Riddikulus, revealing it was Lupin’s Boggart.
• Harry told Scrimgeour that he had founded Dumbledore’s Army for training, and Scrimgeour realized it had nothing to do with Anthony Weasley.
• Harry, Ron, and Hermione said they did not know where Lupin had gone, and Scrimgeour ordered the Aurors to find him.

• Dumbledore watched the Aurors Apparate away and warned Fudge that he hoped the incident would not happen again.

After receiving the Ministry’s treatment fees, Anton and his friends leased the Cabin, Greenhouse, and Animal Paddock from Hogwarts and decided to use the remaining money to buy a shop in Hogsmeade Village or Diagon Alley. The group agreed to search for a building together and began planning how to reach Hogsmeade through Hogwarts’s secret passages.

• Anton questioned whether the group should keep the treatment fees and asked Lupin for advice on sharing the money with the school.
• Lupin told Anton to arrange an official lease with Professor McGonagall, who could set the price and protect the group’s claim to the Cabin, Greenhouse, and Animal Paddock.

• Anton proposed that each member take ten Gold Galleons and use the rest to buy a shop in the Cabin’s name, with rooms upstairs for the group.
• George and Fred listed four secret passages from Hogwarts to Hogsmeade, and everyone agreed to look for a suitable shop that weekend.

Anton and his Cabin friends planned a secret tunnel from their Cabin to the passage beneath the Whomping Willow, then Anton took Hannah and Neville to search for a base in Hogsmeade Village. They found a cheap, barrel-shaped former pub with serious cracks, but Anton suspected an internal problem and led them on to inspect other properties.

• Anton proposed having the Elephant-Eating Vine create a hidden tunnel from Cabin to the passage beneath the Whomping Willow, and the group agreed it would be a Cabin project.
• Anton arranged to look at Hogsmeade properties with Hannah and Neville while the Twins focused on Quidditch training and Lupin had time to visit his wife.

• Anton led Hannah and Neville to a three-story, barrel-shaped former pub near Hog's Head that was unusually cheap.
• Neville pointed out a huge crack in the building, while Hannah hoped the Elephant-Eating Vine could help rebuild it.
• Anton judged that the cracks spread from inside and that the house had a deeper problem, so he left to inspect other properties as Hannah looked back at it.

Anton and his friends inspected a suspiciously cheap house and discovered it was filled with strange magical plants resembling human body parts. After disarming the owner, Anton realized the house was a valuable source of potion ingredients and coaxed the frightened man into explaining what had happened.

• Anton, Neville, and Hannah considered buying the dilapidated house, and Neville's crystal ball alerted them that George and Fred had arrived.
• George and Fred eagerly proposed exploring the house, while Anton insisted they wait for the owner's permission.

• Anton disarmed the owner when he threatened them, then identified the apparent organs as valuable magical plants and mushrooms.
• Anton comforted the sobbing owner and asked him to explain what had happened in the house.

• Bach Bierhoff told Anton and the others how he captured a Siren, built a successful bar, and lost his wife and wealth when it burned down.

• Anton recognized the property as a trove of valuable magical plants and decided it belonged to him.

Anton and his friends explored the monster-filled house and negotiated with its owner, Bach, who was desperate to sell it. After Anton frightened Bach into offering half price, Bach returned with an even lower offer of forty percent, leaving Anton wavering.

• Neville admitted he had wanted to use the Cruciatus Curse for justice but had stopped himself, and Anton urged him to reflect on what justice meant.

• Anton told his friends to let Bach stew until the next weekend, expecting anxiety to make him lower the price further.
• Bach returned and offered to sell the house for forty percent of its original price, and Anton hesitated while looking toward the second floor.

Anton and his friends bought Bach’s house in Hogsmeade after he offered information about Professor McGonagall. Bach revealed that McGonagall’s husband might still be alive, and Anton stunned him so McGonagall could investigate; the group then headed to bring Bach to her despite their worries about being caught out of school.

Bach left with his debts paid and revealed that Professor McGonagall’s supposedly dead husband had once been seen walking again.

• Anton’s friends explored the house’s rare magical plants as a Venomous Tentacula attacked, and Anton drove it back with a freezing spell.

• Professor McGonagall found Elphinstone trapped inside the Venomous Tentacula and promised to get him out.
• Anton watched through his Three Eye Spells as McGonagall expanded the second floor and formed a glass sphere around the Tentacula and its surroundings.
