Gon and the others are headed to the Servant's Quarters. Zebro offered some special training. They discovered that everything in that house is heavy. They began training. Leorio and Kurapika tried to open the gate and they moved the gate. The next day, Gon helped them and successfully opened the gate. They left the quarters and headed for the mansion. They encountered a trainee butler that kicks out whoever crosses the line. Gon crossed the line and hit badly. He never stopped trying until his anger destroyed a part of a wall. The butler cried and Killua's mother hit the head of the butler and she told a saddening message from Killua.
