After defeating the Circhester Gym, you will have dinner with Sonia and Hop. One thing will lead to another, and the three of you will then venture to the nearby Hero's Bath. Once there, Hop will challenge you to another battle. This time, you will see a number of familiar Pokemon within Hop's Team, as well as one not seen previously. This is where Hop's Final Pokemon Team begins to take shape. Even if defeated, Hop will feel encouraged to continue attempting to defeat the Circhester Gym.
