Dragon was invited to a small party at the Moby Dick. He chose Sabo, Luffy, and you to come with.

Whitebeard and his crew wanted to ally, or at least take away the tension, between their crew and the Revolutionary army.

(Diff!AU, Sabo knows his past earlier)

They were sailing on the Wind Gamma, Dragon had allowed Ivankov to be in charge of the Army until he came back.

The wind hit your face as Dragon stood at the front of the ship, Sabo and Luffy playing tic-tac-toe on the deck.
