The Dueling Club Begins

A New Activity
Lockhart's Announcement
Lockhart starts a Dueling Club to boost morale. He and Snape demonstrate, but Lockhart is easily defeated. The students are paired up.
The Pairing
Snape deliberately pairs Harry with Draco Malfoy. They duel, and Harry uses a Tickling Charm, while Draco uses a leg-locker curse. The duel is a draw.
The Serpent
Draco then conjures a snake with “Serpensortia.” Lockhart tries to remove it but fails. The snake slithers toward Justin Finch-Fletchley.
Harry Speaks Parseltongue

The Unexpected Ability
The Command
Harry, without thinking, speaks to the snake in Parseltongue, telling it to leave Justin alone. The snake obeys. The crowd is stunned, and Justin is more frightened than grateful.
The Aftermath
Ron and Hermione explain that Parseltongue is rare and associated with Dark wizards, especially Salazar Slytherin. Harry becomes the prime suspect as the Heir.
The Turning Point
This incident changes the school's perception of Harry. Even his friends are uneasy. The revelation forces Harry to confront his own identity and connection to Voldemort.
The Spread of Rumors

The Accusations
Whispers in the Halls
Students begin to avoid Harry. Ernie Macmillan publicly accuses him of being the Heir. The Hufflepuffs hide Justin. Harry feels isolated and angry.
The Evidence
Ernie points out that Harry has a grudge against Muggle-borns and that he spoke Parseltongue. The rumors are based on fear, not facts.
The Defense
Harry tries to explain, but few listen. The conflict between truth and suspicion is a central theme. Only his closest friends trust him.
