The Hogwarts Express arrived safely at King's Cross, and Dumbledore told Andrew that the curse affecting Hogwarts professors had vanished, likely because Voldemort had lifted it after completing his resurrection. Dumbledore warned Andrew that Voldemort would target him during his upcoming visit to Brazil and said Moody would accompany him.

• Andrew organized the Prefects to guide students through the King's Cross crowds after the train arrived safely.

Andrew traveled with Dumbledore toward Castelobruxo, learning Herbology while Dumbledore tried to persuade him to become a Hogwarts teacher and eventually headmaster. Andrew refused the leadership role but agreed that teaching Alchemy could be worthwhile, while Dumbledore privately remained convinced Andrew was a strong candidate for the job.

• Andrew discussed herbs with Dumbledore and discovered that Dumbledore had read through the entire Hogwarts library as a student.

Andrew traveled to Brazil to study Castelobruxo’s Dream Tree research and learned that Professor Marcus and the school had created Aisha, a highly aware plant whose dreams could be explored. Marcus led Andrew and Professor Moody through a remote rainforest toward Aisha, promising that she would appear like a magnificent temple.

• Andrew declined a Brazilian Ministry banquet invitation so he could meet a professor at Castelobruxo and study the Dream Tree.

Andrew oversaw Hogwarts’ large-scale installation of magical lighting while Hagrid, Harry, and Sirius turned the work into a spectacle. Sirius told Andrew that Diagon Alley had changed dramatically, especially the renovated Leaky Cauldron, leaving Andrew reflecting on the Wizarding world’s material progress.

• Andrew watched Hagrid swing a streetlight pole as Harry and Sirius cheered him on.
• Andrew explained that Hogwarts was installing lights throughout the Common Rooms, grounds, Library, and corridors, with Filch and the professors helping supervise.

• Sirius urged Andrew to visit Diagon Alley and described the Leaky Cauldron’s three floors, including a family area with desserts, Alchemy machines, and Dream Playback.
• Andrew questioned how much the Wizarding world had changed and considered how money, supplies, and magic had helped drive Diagon Alley’s growth.

They dismissed the Pure-bloods’ complaints about technological change, leaving Harry eager to hear how the upheaval might affect the Malfoys.

• Andrew noticed Diagon Alley had become more lively and magical, and Sirius described wizards secretly performing real magic on the Muggle side to learn about Muggles firsthand.
• Sirius proposed that he and Harry team up as a traveling magician and money collector, then offered to show Andrew the Ministry’s dream screenings and park.
• Andrew inferred that the Ministry might be preparing to cultivate a Dream Tree near Diagon Alley and considered how it could support a new shopping area.
• After visiting Diagon Alley and The Leaky Cauldron, Andrew concluded that Fudge’s economic subsidies had given wizards more money and time to pursue entertainment, Muggle studies, and abandoned ambitions.
• Sirius and Andrew brushed off the Pure-bloods’ complaints about costly upgrades, while Harry worried about how the changes could affect the Malfoys.

The Weasley family began renovating The Burrow, with Mr. Weasley assigning Percy to help and promising the children larger rooms of their own.

Andrew studied how different magical traditions produced similar effects through different incantations and casting methods, then experimented with casting magic through intent alone. In his laboratory, he successfully levitated parchment, Transfigured it into a key, and opened a lock using the same strange spoken phrase, leaving him convinced he had discovered a new way to cast spells.

• Andrew compared charms from Hogwarts, Uganda, Brazil, and Ilvermorny, noting that similar effects came from different incantations and techniques.
• Andrew moved his books and research to his laboratory and tested different ways of casting the Levitation Charm.
• Andrew made a paper ball float by focusing on the desired effect while speaking the phrase “Tian Wenjing, I—” instead of a familiar incantation.
• Andrew used the same phrase while Transfiguring the paper ball into a silver-white key.
• Andrew cast another spell with the phrase, and the lock he had made sprang open.

Andrew discovered that incantations could be adapted to suit each wizard, and he began to understand how personal casting styles developed. He then realized that Transfiguration could potentially be layered onto spells, an idea he had seen Dumbledore demonstrate.

• Andrew tested substitute incantations for the Levitation Charm and concluded that its established wording was the best general-purpose option.
• He devised new incantations and wand movements for the Water-Making Spell, successfully casting several variations.
• Andrew realized that the best incantations might differ for each wizard and that years of practice had shaped Moody's and Flitwick's distinctive casting styles.
• He tested his improvised incantations on first-year spells and found that they produced similar effects, marking his first real progress in Charms.
• Andrew wondered whether he could use Transfiguration to alter or strengthen spells and recalled Dumbledore layering Transfiguration onto a spell.
