I just want a few things here and there to reassure Satoshi didn't forget some of his past experiences with pokemon species, people or places.
I'm kind of tired of old characters showing up, specially when half the time they're very out of character. I mean people like Kasumi, Haruka, Takeshi and other former companions or former rivals.
People like Handsome are perfectly fine.
Then again I think it would be fun to have an episode Takeshi shows up, teams with Eureka and they try to push Citron into approaching some girl he actually ends having a crush at.
Edit: Ok. No. Really. I would LOVE if Glion returned for one or more episodes <3 <3 <3 <3 <3 <3
