Jack is incredibly brave. His ship is attacked by samurai pirates searching for a map that his father has hidden. When they try to use Jack to bribe his father into telling the location of the map, his father caves and tells them. Unfortunately, they plan to kill Jack anyways. When his father realizes this, he fights back. Jack watches his father get killed, and the pirates, thinking he's dead, leave him lying on the deck. With his dying breath, Jack's father tells him the location of the hidden map, so he sneaks down to the cabin to retrieve it. These actions show bravery because he risks his life trying to find it. When the samurai sees him, he ends up jumping overboard.
