I think the episode was cute, but her goal is to become a Dragon Master but the stupid writers keep doing things their own way.How can she become a Dragon Master while only having a stupid Axew
that probably wont evolve like Piplup
and having Excadrill
that are not Dragon Types.Since Iris's goal is similar to Misty's focusing on training types they specialize in. Misty has the knowledge and the Pokemon that will get her to become a Water Pokemon Master while Iris only has the knowledge but not the Pokemon necessary to become a Dragon Master.If she had Pokemon like Krookodile
that can learn Dragon Types moves thats another story.
