Eventually, they meet a tough Trainer named Narissa, who reveals that the culprits are her two Ditto. Ash pounces at the opportunity and challenges her to a battle!

Narissa makes several rookie errors during the battle and gets really angry when she loses. When Brock asks about her strategy, she breaks down in tears and confesses that her tough-girl act is just that! With his help and Ash’s advice, she improves her battle skills—enough to defeat Team Rocket when they show up!
