After four Slytherin students were killed, Hogwarts returned to routine until Gilderoy Lockhart announced a Dueling Club, which Sean joined with Blaise. At the first meeting, Lockhart introduced Professor Snape as his assistant, while Sean watched Malfoy and Millicent, who held the Diary.

• Hogwarts students soon stopped discussing the deaths of the four Slytherin students, and a new fifth-year male Prefect took over Dickie's position.

After Harry spoke Parseltongue to control the snake, students accused him of being the Heir of Slytherin and responsible for the attacks. Sean reassured Harry, but when Sean returned to the Slytherin Common Room with Blaise, the older students demanded an explanation about his claim that the Heir was in Gryffindor.

Sean and the Slytherins met to reject the idea that Harry Potter was Slytherin’s heir and agreed to search for the real heir. Back in his room, Sean surprised Kulkan by ordering raw eggs and fresh meat after she complained about her food.
