On the way to Iccirus City, Ash and friends head to a nearby town to stay at the Battle Club for the night. At the club they witness a battle between a trainer named Shamus and another trainer. After the battle they see Shamus demanding the other trainer to give up one of his Pokémon. They quickly intervene and stop him. While eating dinner later, Tepig recognizes Shamus as the trainer that abandoned it in Accumula Town. Shamus is not phased to see Tepig and does not care that he abandoned it, saying it has no potential. This makes Ash and Iris extremely upset and Ash decides to prove Tepig has potential by battling Shamus, to which Shamus happily agrees.
