Chapter Summaries

Lynn applied for a Time-Turner, and Dumbledore explained how using it could alter future events without changing what had already happened. The chapter ended with Harry and Ron’s exhausted conversation interrupted by a huge explosion that shook the castle.

• Harry and Ron complained about the harsh punishments they had worked through that afternoon and wondered why Hermione had been avoiding them.
• Harry and Ron decided to secretly investigate Hermione, but a massive explosion suddenly shook the castle.
• Lynn signed an undertaking promising to use the Time-Turner only for his studies.
• Dumbledore explained that a Time-Turner could let a student attend two classes scheduled at the same time without changing established history.
• Lynn realized that the Time-Turner’s version of history depended on what people knew at the moment it was used, and Dumbledore said objective history had already changed.

Lynn discussed the dangers of using the Time-Turner with Dumbledore and wondered whether his future self had taken the basilisk from the Chamber of Secrets. After learning that Gellert Grindelwald had signed his Hogsmeade permission form, Lynn began his journey three weeks into the past.

• Lynn asked Dumbledore whether he could witness the basilisk's release and learned he must not alter established history or be seen twice on the same timeline.
• Lynn and Dumbledore considered whether Lynn himself had opened the Chamber of Secrets and taken the basilisk, but they could not determine the truth.
• Dumbledore gave Lynn a Hogsmeade permission form signed by his great-uncle, Gellert Grindelwald, and passed on Grindelwald's warning about overlooked dangers.
• Lynn set the Time-Turner to take him back to the start-of-term feast on September 1, and Dumbledore told him to return to the office at 10:16 p.m. on September 21.
• Lynn began turning the Time-Turner's hand backward, and a thunderous boom rang in his ears.

Lynn used the Time-Turner to return to Hogwarts on September 1 and confirmed the basilisk was still in the Chamber of Secrets. He left the basilisk alone and began watching the bathroom entrance for whoever would take it, while Myrtle’s crying made his wait miserable.

• Lynn counted 483 hours and fifteen minutes backward on the Time-Turner and arrived at Hogwarts during the opening feast on September 1.
• Lynn confirmed the date when Snape brought Harry and Ron into the castle after their flying car crashed into the Whomping Willow.
• Lynn entered the Chamber of Secrets with Tom and found a fresh-looking basilisk shed skin, showing someone had visited after term began.
• Lynn listened as Tom translated the basilisk’s words and confirmed that it was still inside the Chamber of Secrets.
• Lynn left the basilisk untouched, gathered food, and began watching the girls’ bathroom entrance for the person who would remove it.
• Myrtle returned to the bathroom crying about being excluded by the ghosts, disrupting Lynn’s attempt to rest.

Lynn hid in the first-floor bathroom while waiting for Myrtle to leave so he could watch for whoever opened the Chamber of Secrets. After Myrtle departed for a ghost council and a suspicious shadow entered the bathroom, Lynn woke and prepared to act.

• Lynn overheard Ravenclaw first-years Beshilde and Lisa discuss Myrtle, then answered Beshilde’s question about dark magic while disguised as Professor Lockhart.
• Lynn recalled that Beshilde would ask his future self the same question a week later and continued hiding in the bathroom while monitoring Myrtle.
• The Fat Friar arrived to invite Myrtle to the ghost council, and she left with him.
• Ginny entered the bathroom to use it while Myrtle was away, then left without incident.
• Late that night, a shadowy figure silently entered the bathroom, and Lynn snapped awake.

Lynn discovered that Hubert Maclean had entered the Chamber of Secrets, taken the basilisk’s shed skin, and spoken to the basilisk in awkward Parseltongue. After failing to uncover Hubert’s motives through surveillance, Lynn stunned and captured him on September 8.

• Lynn followed a dark figure into the Chamber of Secrets and watched him pack away the basilisk’s shed skin.
• Lynn recognized the intruder as Hubert Maclean, a third-year Slytherin, and heard him speak to the basilisk in Parseltongue before it left through the pipes.
• Tom told Lynn that Hubert’s Parseltongue sounded like an awkward imitation and that he had mentioned going to a treasure place.
• Lynn waited in the Slytherin common room and watched Hubert return in the morning, then followed him for a day but found no suspicious behavior or pouch.
• After Professor McGonagall kept Hubert late to redo an assignment, Lynn stunned him in a corridor and carried him toward the Room of Requirement.

Lynn interrogated Hubert McLean with Veritaserum and discovered that Hubert had spoken Parseltongue about moving the basilisk to a hidden treasure site in Hogsmeade. After the potion wore off, Lynn erased Hubert’s memory of the interrogation.

• Lynn gave Hubert Veritaserum and learned that Hubert’s father, Terls McLean, was corrupt and had hidden an incriminating ledger.
• Hubert denied visiting the Chamber of Secrets or knowing about the black bag, but said a strange sound had been echoing in his mind.
• Hubert repeated the sound in Parseltongue, and Tom translated his words about hiding the basilisk at a former treasure site in Hogsmeade.
• Lynn wondered whether the self-proclaimed Slytherin heir was a Horcrux or someone else, then questioned Hubert as the Veritaserum wore off.
• Lynn claimed Dumbledore had authorized the questioning and cast Obliviate on Hubert.

Lynn erased Hubert’s memories of their encounter and investigated the possible identity of the Parseltongue speaker claiming to be Slytherin’s heir. Suspecting the Basilisk might be hidden in Hogsmeade, Lynn searched the Shrieking Shack, then went to The Hog’s Head to offer a thousand Galleons for useful stories.

• Lynn altered Hubert’s memories so he remembered being scolded by Professor Lockhart after complaining about homework.
• Lynn ruled out Tom’s main soul fragment and the Diary Horcrux as likely culprits, and considered whether the heir might be the fragment inside Harry or someone unknown.
• Lynn suspected the Basilisk might be hidden at the Shrieking Shack and flew there in crow form, but found nothing.
• Lynn entered Hogsmeade disguised as a middle-aged man and went to The Hog’s Head to seek information.
• Lynn offered a thousand Galleons for a story about Hogsmeade, prompting the pub’s patrons to crowd around and compete to tell him one.

Lynn paid Hogsmeade residents to share stories, hoping to uncover useful leads about the village. Ambrose Flume told him about a werewolf in the Shrieking Shack and a hidden goblin prisoner camp, leaving Lynn interested in investigating places that might conceal something.

• Lynn paid Aberforth Dumbledore to reserve The Hog's Head and keep the storytellers in order.
• Lynn paid an unfamiliar wizard for recounting Hogsmeade's founding, then set rules for the stories and their rewards.
• Ambrose Flume told Lynn that a werewolf had howled in the Shrieking Shack on full-moon nights, and Lynn paid him a Galleon.
• Flume described a goblin prisoner-of-war camp beneath Hogsmeade, where his ancestor had died, and said his family had never found the remains.
• Lynn rewarded Flume with ten Galleons and considered the camp a possible place to investigate.

Lynn spent the day collecting Hogsmeade legends, finding only two potentially useful leads. After Aberforth recommended Granny Daniel as a knowledgeable longtime resident, Lynn went to the Owl Post Office to meet her.

• Lynn heard fabricated stories at The Hog's Head and paid only for a tale about a goblin prisoner-of-war camp and a mysterious door that led somewhere unknown.
• Lynn paid Aberforth the remaining venue fee and learned that Granny Daniel, the Owl Post Office keeper, had lived in Hogsmeade for over a hundred years.
• Aberforth told Lynn not to offer Granny Daniel money and to say that the owner of The Hog's Head had sent him.
• Lynn went to the Owl Post Office and asked the employee on duty to see Granny Daniel.

Lynn visited Granny Daniel to learn about a hidden place in Hogsmeade that might once have held the basilisk. She concluded that its entrance might be at Hogwarts and pointed Lynn toward the Ravenclaw ghost, while privately recognizing him as a traveler through time.

• Lynn found Granny Daniel at the Owl Post Office and told her he was searching for a concealed, spacious place in Hogsmeade.
• Granny Daniel described a legend about goblins building large underground cellars and a possible hidden treasury in Hogsmeade.
• Granny Daniel reasoned that since Flume's family had searched Hogsmeade for generations, the cellar entrance might be elsewhere, possibly at Hogwarts.
• Granny Daniel suggested that Hogwarts ghosts might know about an old entrance and singled out the lady who lived in Ravenclaw Tower.
• Lynn thanked Granny Daniel and left, while she reflected that he was a traveler through time and the foremost star of Hogwarts.

Lynn planned to use Ravenclaw’s diadem to persuade the Grey Lady to reveal the entrance to the goblin-built cellar at Hogwarts. He found the diadem in the Room of Requirement and prepared to learn Fiendfyre so he could destroy it.

• Lynn returned to Hogwarts after speaking with Granny Denys and considered how to approach the Grey Lady, Helena Ravenclaw.
• Lynn realized he could offer to find and destroy Ravenclaw’s diadem in exchange for the cellar entrance’s location.
• Lynn entered the Room of Requirement’s hidden storage room and found Ravenclaw’s diadem on a bust atop an old cabinet.
• Lynn took the diadem but postponed meeting the Grey Lady until he could resolve the problem of his identity.
• Lynn decided to learn Fiendfyre, whose incantation he had memorized, as a way to destroy the diadem.

After nearly a week of practicing Fiendfyre in the Room of Requirement, Lynn ran into Hermione, who had worked out that Umr had been impersonating him at Hogwarts. Their conversation ended with Lynn asking Hermione for a favor.

• Lynn spent nearly a week practicing Fiendfyre until he could wield it freely, though he had not mastered it.
• Lynn left the Room of Requirement to get food and met Hermione, who was carrying books for Professor Flitwick.
• Hermione confronted Lynn and revealed that she knew Umr had been attending classes in his place while the real Lynn hid in the castle.
• Lynn confirmed Hermione’s guess and asked her to keep the secret, then claimed he might be working to save Hogwarts.
• When Hermione asked what he had been doing, Lynn stared at her and seriously asked her for a favor.

Lynn told Hermione that he was investigating the missing basilisk and asked to borrow her identity so he could speak with the Grey Lady without revealing himself. Hermione agreed to help, and Lynn disguised himself as her while she hid in the Room of Requirement.

• Hermione carried spellbooks to Professor Flitwick, took one of his cakes, and left for the Great Hall.
• Lynn explained to Hermione how he had found Tom's Diary, entered the Chamber of Secrets, and discovered that the basilisk had vanished.
• Hermione worried that Lynn was taking too much danger upon himself, but accepted that he was determined to investigate.
• Lynn asked to use Hermione's identity to question the Grey Lady about the entrance to a goblin-built underground cellar in Hogwarts Castle.
• Lynn planned for Hermione to hide in the Room of Requirement and help verify whether medieval goblins had built a treasure site in Hogsmeade.

Lynn used Hermione’s appearance to move around Hogwarts, tutored Harry and Ron in Charms, and then searched for the Grey Lady. Nearly Headless Nick directed him to ask the Fat Friar, who had spoken with her that afternoon.

• Lynn delivered books for Professor Flitwick, then joined Harry and Ron in the Great Hall and questioned them about their flying car.
• Lynn dragged Harry and Ron to the library and made them finish their Charms homework before letting them leave.
• Lynn gave up on tutoring them in Defense Against the Dark Arts because it was getting late and he still needed to find the Grey Lady.
• Lynn asked Nearly Headless Nick where to find the Grey Lady, and Nick suggested asking the Fat Friar.

Lynn helped the Fat Friar remove Peeves’s basket of rotten eggs, then went looking for the Grey Lady near Ravenclaw’s common room. He met Luna Lovegood, who offered to call the ghost if he solved the door knocker’s riddle, and the chapter ended as Lynn considered his answer.

• Lynn used Accio to remove Peeves’s basket of rotten eggs from above a classroom door, earning praise from the Fat Friar.
• The Fat Friar told Lynn that the Grey Lady was probably in Ravenclaw’s common room.
• Lynn headed to Ravenclaw’s tower and met Luna Lovegood on the stairs.
• Luna agreed to help Lynn call the Grey Lady if he solved the eagle-shaped door knocker’s riddle.
• The knocker asked, “Lighter than a feather, empty inside, yet even a giant cannot lift it,” and Luna urged Lynn to answer.

Lynn, disguised as Hermione, summoned Grey Lady and revealed that he had found Ravenclaw’s lost diadem. Grey Lady recognized it, and Lynn explained that it had been corrupted by an evil soul.

• Lynn answered the Ravenclaw door knocker’s riddle, but declined Luna’s invitation to enter the common room.
• Lynn asked Luna to bring Grey Lady to him, and she led the ghost outside.
• Lynn told Grey Lady he wanted to help her and asked where her mother’s diadem was.
• Lynn showed Grey Lady the diadem, and she recognized the treasure she had lost.
• Lynn told Grey Lady that an evil soul had corrupted the diadem.

Lynn revealed that Tom Riddle had turned Rowena Ravenclaw’s diadem into a Horcrux, then struck a deal with the Grey Lady for information about a place goblins built at Hogwarts before 1612. The Grey Lady agreed to tell him how to find it after he helped destroy the diadem, though entering would require overcoming its restrictions.

• Lynn explained that the diadem was a Horcrux, and the Grey Lady realized Tom Riddle had deceived her and corrupted her mother’s heirloom.
• The Grey Lady panicked that Voldemort could not die, but Lynn reassured her that he was no longer a threat and that Dumbledore knew about the Horcruxes.
• When the Grey Lady questioned Lynn’s identity, he showed her a phoenix feather from Dumbledore, convincing her that Dumbledore trusted him.
• Lynn offered to destroy the diadem in exchange for the Grey Lady’s knowledge of a place goblins had built within Hogwarts before roughly 1612.
• After recalling the ancient matter, the Grey Lady agreed to explain how to find the place and warned Lynn that its entrance had restrictions.
• Lynn agreed to deal with the Horcrux first.

Lynn destroyed the Horcrux hidden in Ravenclaw’s diadem with Fiendfyre, then pressed the Grey Lady to reveal what she had promised. She told him that he needed the recognition of three objects to learn the hidden place’s location, leaving Lynn puzzled by the clues and Slytherin’s absence.

• Lynn explained to the Grey Lady that the diadem and its Horcrux could not be separated, then prepared to destroy them with Fiendfyre.
• Lynn burned the diadem, and Fiendfyre consumed Voldemort’s soul fragment before Lynn countered the spell when it turned on him.
• Lynn tried and failed to restore the ruined diadem, then demanded that the Grey Lady honor her promise.
• The Grey Lady said Lynn needed recognition from Ravenclaw’s knocker eagle, Gryffindor’s Sorting Hat, and Hufflepuff’s kitchen painting to discover the hidden place’s location.
• Lynn wondered why the clues involved three Founders’ objects and excluded Slytherin.

Lynn investigated the Grey Lady's clue about the basilisk's hiding place and questioned the Sorting Hat in the Headmaster's office. The hat explained its connection to Gryffindor and said Harry's strong Slytherin traits had made it consider him Slytherin's heir.

• Lynn returned to the Room of Requirement and recounted his meeting with the Grey Lady to Hermione, who asked about the basilisk's hiding place.
• The next evening, Lynn identified the knocker eagle, Sorting Hat, and kitchen painting as the three things the Grey Lady had mentioned.
• Lynn entered the Headmaster's office, tried to retrieve the Sword of Gryffindor from the Sorting Hat, and put the hat on when he found nothing.
• The Sorting Hat begged Lynn not to wear it or try to take the sword, then revealed it had once been Gryffindor's hat and favored Gryffindor when sorting students.
• The Sorting Hat said Harry's qualities fit both Gryffindor and Slytherin, but his strong Slytherin traces had made it think he was Slytherin's heir.

Lynn questioned the Sorting Hat about his Slytherin placement, and it admitted it had regretted sorting him too hastily because he possessed qualities suited to every House. The Hat then granted him Gryffindor’s recognition and pointed him toward other founder relics, which he would need to find to uncover a goblin-built place of knowledge.

• The Sorting Hat explained that Lynn’s many qualities made him difficult to place and said it regretted sorting him into Slytherin without further consideration.
• Lynn asked whether he could receive the honor, startling the Sorting Hat before it agreed to entrust him with a great responsibility on Godric Gryffindor’s behalf.
• The system awarded Lynn the permanent title Brave and Fearless Gryffindor, which gave him access to Gryffindor privileges and let him see the young wizards’ recognition of him.
• The Sorting Hat told Lynn that he needed recognition from the other founder relics to find a place where knowledge could be obtained, and confirmed that goblins had built it.
• Lynn continued questioning the Sorting Hat, but it became an ordinary hat and no longer spoke.
