In 1992, Shaun went to see Eugene at a maths competition and was disappointed at his failure to win. Upon returning home, he argued with Bronwen and left her. He never returned.

He attended the funeral and sang Danny Boy in memory of his son. Shaun tried to be more involved with Terry, greeting him. He witnessed as Eugene's ghost-like being passed over. (TV: Random Shoes)
