The most touching moment in One Piece. DD was deeply saddened to have lost a brother, and Vergo could die in peace having his efforts be acknowledged by his brother, having sacrificed years of time with the family for building up a fake identity and connections with the G-5, working tirelessly towards the family goals. The G-5 ultimately meant nothing, meaning his love for family was all
that kept him going. The most loyal subordinate one could ever hope to have. Chou Kouku
