Ritchie worries about Zippo because he had been injured in a fierce battle

Note: In this story, Ritchie battled a very tough Pokémon trainer who had a powerful Charizard and Ritchie decided to use Zippo to fight against the other Charizard. The trainer did not expect that Ritchie also has a Charizard and ordered his Charizard to attack Zippo in a very violent way until he was bleeding and could not fight anymore. Ritchie got so worried that he told the trainer to stop it, but the trainer ordered his Charizard to attack him too, but Zippo flew to protect him and doesn't care that he is sacrificing himself. The trainer then got angry that he decided to give up and got on his Charizard to fly away and so, Ritchie and Zippo were saved from the violent trainer, but Ritchie was still worried about Zippo who decided to take him to the Pokémon Center in the end.
