Arc 5The Diary and the Snow Monster
Douglas destroyed Tom Riddle’s diary, then helped the professors investigate the threat around the Chamber of Secrets while Hogwarts continued through exams and Christmas. The arc ended with Douglas teaching the fifth-years to face Boggarts, as Hermione fled after hers took Douglas’s form.
- Douglas received Riddle’s diary from Luna Lovegood, learned that it had offered him power and urged him to release the basilisk, then destroyed it with lightning and brought the remains to Dumbledore.
- Dumbledore explained that Tom Riddle had been his student and might have split his soul, while Douglas inferred that Voldemort had controlled Tom Cruise to investigate Riddle.
- When the professors could not enter Douglas’s office, Harry, Hermione, and Ron warned him, and Douglas passed Snape’s test, then reprimanded the students for investigating him and assigned self-criticisms.
- Douglas coached Hermione in the Stunning Spell, watched Harry win the Quidditch match despite a Bludger targeting him, and helped Harry question Dobby about the danger at Hogwarts.
- Douglas created a Snow Monster for students to defeat, and they brought it down with water and mud before two students won its rune-inscribed plaques.
- Douglas joined the professors for hot pot, oversaw end-of-term exams, held a book event where he exposed Rita Skeeter’s Animagus secret, and celebrated Christmas with friends and the Weasleys.
- Douglas taught the fifth-years the Riddikulus spell and tested them against Boggarts, and Neville and Seamus succeeded, Ron panicked at a spider, and Hermione ran out when her Boggart impersonated Douglas.
