Ryo, a boy in his class, shows him strategies then Masquerade gives Ryo a Doom card and tells him to get revenge on Dan. Dan loses the fight and realizes his mistake in only focusing on the winning and power in Bakugan. Drago then realizes his own mistakes in being hard on Dan. Dan then heads out and manages to get Drago out of the river, both apologizing to each other. They then decide to put their differences aside and work together as a real team. (Source: Wikipedia)
