Ash and co. arrive back in Hearthome City, so that Ash can challenge Fantina to a battle. He then bumps into another Trainer named Barry. Barry reveals that he knows about both Ash and Paul. He says that he idols Paul and trains his Pokémon just like Paul. This upsets Ash and they decide to battle.

The Twinleaf Festival may have been referenced in this episode.
