Ch. 41Mysterious Person
Sean and the others faced an Imperius-controlled Kettleburn and a hidden attacker who directed the Ashwinders. Sean trapped the group behind blue flames, but the attacker enlarged the Ashwinders and surrounded them, leaving them in danger.
- Sean recognized that Kettleburn was guarding something and heard a hidden voice order him to attack the students.
- Charlotte, Cedric, and George fought Kettleburn while Sean brought the unconscious Madam Pomfrey and Percy to safety.
- A thrown potion drew the Ashwinders toward the group, so Sean cast Protego Diabolica to shield them with blue flames.
- The hidden voice used Parseltongue to stop the Ashwinders and gather them around the flames, making Sean suspect the speaker was Tom Riddle.
- The attacker enlarged dozens of Ashwinders, surrounding the small ring of fire as the creatures began to tremble.
