After winning duels against Harry, Sean gained Mystic Hand and Magic Affinity, then traveled to the Gaunt Old House to find Marvolo Gaunt's Ring. He bypassed the house's defenses with Alchemical Puppets, but had to enter the cursed house himself to reach the protected cabinet.

• Rowena demonstrated a faster, stronger Sectumsempra and repeatedly sliced Sean apart, ordering him to defeat her with the same spell.

Sean trained three spells with Ravenclaw in her Dressing Mirror until its magic ran out and the mirror-space began to collapse. Before sending him back, Ravenclaw asked him to give her damaged Diadem to her daughter Helena and revealed a hidden Jewelry Box on the middle bookshelf.

• Ravenclaw recognized that Sean's mental strength could support upgrading two more spells, and Sean chose the Disillusionment Charm and Thunderbolt alongside Sectumsempra.
• After Sean completed his spell training, Ravenclaw told him the mirror had reached its limit and urged him to leave before its space collapsed.
• Sean told Ravenclaw that he had found her damaged Diadem and that Helena had become a ghost; Ravenclaw asked him to tell Helena she had never blamed her.
