- Su Er stored the Philosopher’s Stone in his family vault, found his mother’s diary, and learned how much she had loved him.
- Su Er returned to Hogwarts, studied Animagus and group-target magic, and stood up to Malfoy after he insulted Hermione.
- Su Er used Harry’s Invisibility Cloak to frighten Malfoy and plant Dungbombs, then avoided punishment when Lucius’s demand for a wand test proved nothing.
- Su Er joined Harry, Hermione, and Ron at Nearly Headless Nick’s Deathday Party, then investigated after Harry heard a strange voice and Mrs. Norris was found hanging beneath the Chamber’s warning.
- Su Er and his friends heard Professor Binns explain the Chamber legend, searched the attack corridor, and questioned Moaning Myrtle in the girls’ bathroom.
- Su Er returned alone to the bathroom, learned Myrtle had seen a boy with thick hair and enormous yellow eyes, and found a faint snake marking on a tap that never produced water.
