He could observe how different trainers in the new setting interact with their Pokemon and apply those lessons to his own relationships.

This could inspire Ash to explore different ways of connecting with his own Pokemon, leading to his character growth.
An old - fashioned Pokemon breeder who has a deep connection with the traditional ways of raising Pokemon.
