Pokemon Performances in all their glory!
It seems as though these performances have quite the diverse set of facets to them. Creating Pokepuffs seems to be an aspect and will likely but at least a minor part of the display (hopefully this means we’ll see more of Miette). Fashion, for both pokemon and the trainer, seems to be a focal point, as is stage presence. Not only will they have to be able to look their best on the stage and runway, they’ll also have to perform contest appeal-like displays of their talent to enthrall audiences.
All of this falls under the numerous interests of Serena, which means this vocation would be absolutely perfect for her. Assuming she can conquer her anxieties around being so well-known in the public eye (something she’ll need to work on if her reaction to the rival trio’s adoration is any indication), this is something that Serena should absolutely excel in. Her few featured episodes leading up to this introduction to Pokemon Performances showed that her cooking, fashion-oriented, and bond with her pokemon, is a very good fit for her.
If this isn’t a goal and dream for her to pursue, I don’t know what will be.
