The Mandarin Island Miss Match

While on Mandarin Island, Ash learns that Prima, one of Orange Island's best trainers, is there as well. When they meet, Prima won't battle. Angered, Ash challenges a passer-by and uses Charizard who, as usual, doesn't listen. Prima uses Slowbro and brings down Charizard. Finally, Prima agrees to battle Ash, and after he loses she gives him some advice: if he listens to his heart and the heart of his Pokemon, he will be a great Pokemon Master.
