Ash and friends encounter a trainer named Katharine who is constantly being manipulated by her bratty Gothita. When Gothita takes a liking toward Ash's Scraggy, it tries to push Katharine into trading one of her other pokemon for the Shedding pokemon. Ash rejects the offer, but is finally persuaded to a battle with Katharine to determine the outcome. Will Ash lose Scraggy, and will the Gothita ever learn to show some respect?
