Bull, an old acquaintance with whom Diego fell out, pays him a surprise visit. Bull confronts Diego to a duel to win his 'diamond'. They arrange to meet that night. Diego can't avoid this and panics. Surprisingly, his friends refuse to help him - they think Diego should accept this duel even if he loses. Ziggy suggests a small wish just to be on the safe side.

Diego wishes to win the duel with Bull, but receives a few marbles. Ziggy is puzzled but Diego is confident. With the magical marbles, he can defeat Bull and keep his 'diamond', a unique Captain Justice marble! But as they try the marbles out, Diego and Ziggy return into the past, just as boastful little Diego was about to face Bull. At the time, he arranged for the game to be banned from school rather than risk losing his precious marble. But today, he must change the past!
