Chapter Summaries

Harry, Draco, Cedric, and Vizet discussed the Golden Egg’s clues and worked out that the Second Task would take place deep in the Black Lake, where they might encounter merfolk. Cedric’s books from Cho Chang revealed underwater dangers, leaving the group to prepare for creatures such as Grindylows and Lobalugs.

• Harry explained that the Golden Egg’s song pointed toward a task at the bottom of the lake and said the champions might encounter merfolk.
• Harry, Draco, Cedric, and Vizet discussed whether they would lose their Wands, and Draco proposed asking his father to investigate rules the champions could use to prepare.
• Vizet reasoned that the tournament’s Alchemy clues and the Goblet of Fire’s Magic Contract likely meant the champions would be allowed to make preparations in advance.
• Cedric summoned the Christmas gift Cho Chang had given him and realized her books about underwater Magical creatures could help with the task.
• Cedric read that merfolk domesticated Grindylows and Lobalugs, and that Lobalugs could release toxins.

Harry, Vizet, Cedric, and Draco discussed underwater dangers and ways to prepare for the Second Task, including spells, Gillyweed, and possible creatures in the Black Lake. Vizet said he could solve the problem of keeping warm, provided they had mastered the Patronus Charm.

• Harry recalled using the Extraction Charm against Grindylows, and Vizet explained that underwater it produced a jet of high-temperature water that could serve as an attack.
• Cedric introduced Gillyweed as a way to grow gills and webbing for over an hour, while Draco remained disgusted and wanted to wait for the Ministry's instructions.

• Vizet warned that a Horned Serpent might appear and described its strength, size, and ability to manipulate currents with magic.
• Vizet said he had a way to keep them warm, but it required mastering the Patronus Charm.

Vizet explained how the Patronus Charm could counter the effects of Dementors and proposed using survival instinct to sustain it underwater. The group agreed that they needed to practice, but debated where they could do so without revealing their plans.

• Vizet asked Draco and Harry to recall how Dementors affected them, then connected those effects to the Patronus Charm’s ability to provide warmth and protection.
• Draco described using a proud, honorable memory to cast the Patronus Charm, and Vizet explained that the charm could fill and protect the caster from within.
• Vizet argued that survival instinct would help a person hold onto the Patronus Charm underwater until the danger passed.
• Harry suggested practicing in the Black Lake, but Draco warned that the other schools’ headmasters might discover what they were doing.
• Cedric proposed practicing in the large pool in the Prefects’ Bathroom instead.

Vizet created a bookcase portal that recreated the bottom of the Black Lake so Harry, Draco, and Cedric could practice the Patronus Charm in harsher conditions. Harry rushed in without protection, then returned coughing and prepared to try again with the Bubblehead Charm.

• Draco argued that the Prefects' Bathroom was too comfortable for practicing the Patronus Charm, and Cedric agreed with him.
• Vizet used the Spiritual Resonance Symphony to turn a bookcase into a space resembling the bottom of the Black Lake.
• Vizet tested the space, returned to the classroom, and added ropes so the others could climb back out.
• Harry plunged into the water without a Bubblehead Charm and returned coughing, while Cedric helped him recover and Draco teased him.
• Cedric urged Harry to be cautious, and Harry cast the Bubblehead Charm before continuing.

Harry, Draco, and Cedric practiced the Patronus Charm underwater while Vizet wrote a paper about the spell and how magic affected wizards. Vizet discussed the dangers of Dark Magic and encouraged Draco to explore familiar spells, leaving him curious about how the Dancing Feet Spell had once helped cause a volcanic eruption.

• Harry, Draco, and Cedric practiced casting the Patronus Charm in the freezing lake water, gradually becoming faster as they adapted to the cold.
• Vizet showed the trio his paper on the Patronus Charm, prompting Harry to resume practicing and Draco to read its discussion of magic.
• Vizet explained that Dark Magic could build harmful emotions in its caster, while the Patronus Charm could influence a wizard in a positive way.
• Cedric connected Vizet's ideas to Dumbledore's goal for Hogwarts Voice, and Vizet said wizards should find and master magic that suited them.
• When Draco worried that a familiar spell might be weak, Vizet told him the Dancing Feet Spell and the Revival Charm had once helped cause a volcanic eruption, and encouraged him to seek the records.

Vizet and Luna developed an underwater Shield Charm that used Alchemy to turn Black Lake water into a protective barrier. They returned to Hogwarts’s back garden and sat together on their usual bench.

After returning to Hogwarts, Gryffindor students lost points as they imitated Fred and George’s stairway trick, and Professor McGonagall punished the ringleaders by making them copy books. In Hogsmeade, Vizet and Luna visited Aberforth’s bar to arrange a guest room for a meeting about their new product, leaving Aberforth surprised by their plans.

• Fred and George used Obstacle Curses to hop down the Moving Staircase, inspiring Gryffindor students to try the dangerous trick and lose House points after injuries and lateness.

Sirius Black and the others discussed using a Magic Live Broadcast to show the Second Task and help protect the Champions. Neville and Hanna introduced their underwater plant idea and prepared to demonstrate it.

• Vizet guessed that Neville and Hanna planned to use underwater plants, and Fred and George explained that they had wanted to surprise him.
• Neville and Hanna explained that they had used the Life Condensation Curse to transfer Christmas Cactus characteristics onto aquatic plants, then Neville placed a glass bottle on the table to demonstrate their work.

Vizet and the others tested their magical live-broadcast system and discovered that the image grew blurry over long distances. Vizet proposed letting the audience help solve the problem, leaving the team with a possible way to improve the system before the Five Champions Tournament.

• Vizet used the Soul Stone Monocle to examine Neville's aquatic grass and saw how Neville had given it traits from Christmas Cactus and Devil's Snare.
• Neville demonstrated that the grass could sense people within about fifteen feet and make the image appear on Fred and George's screen as he carried it downstairs.
• Luna noticed that the image became blurry, and Aberforth Dumbledore recognized the screen as a Magical Artifact using the Mirage Charm.
• Sirius Black explained to Vizet that the image blurred at greater distances because the lightweight screen could not withstand a stronger Mirage Charm.
• Vizet understood the team's difficulty in finding a solution before the Five Champions Tournament and suggested asking the audience to solve the problem.

Vizet explained that the curtain for the Magic Live Broadcast should include clear instructions that would encourage even New Students to believe they could learn the Mirage Charm.

• Sirius Black compared Vizet’s explanation to the malice needed for Dark Magic, while Lupin compared it to the happy emotions that supported the Patronus Charm.

• Fred and George recalled Sirius Black’s old Animagus notes, which had predicted Peter Pettigrew might fail.

• Neville recited how training alongside knights could make swordsmanship easier through the influence of their shared atmosphere.

Neville explained that Godric Gryffindor’s book described how experiences in a Muggle knight order inspired him to found a school for young wizards. Vizet proposed using the curtain’s written explanation to help spectators cast and strengthen its Mirage Charm, and the group planned to test the method with M’s staff.

• Sirius Black asked Neville who wrote Introduction to Muggle Swordsmanship, and Neville identified the author as Godric Gryffindor, founder of Gryffindor House.

• Dobby confirmed that Kreacher had told him about the Hogsmeade meeting, and Vizet praised Dobby for sharing the cake recipe with Kreacher.
