5 Episodes.
He more than likely won't appear again you say? Yeah, he very likely could.
If he was just an arc specific character, why did he show up in the episode before the Club Battle, instead of just appearing in the Club Battle.
He hasn't appeared since then, well neither has Stephan, Burgundy or Georgia.
None of the rivals are Main Characters, but recurring characters, so Luke could still be a recurring character since he was built up then an "arc specific
character.
So did Burgundy and Georgia.
Then that means Georgia and Burgundy are worthless too. Stephan and Luke aren't useless in my opinion, especially not Stephan.
The thing is, we agree, but we disagree on how these characters are to be used. I can see that Georgia, Burgundy, Luke, and Stephan are recurring characters, but not all necessarily as rivals.
I just don't think that should be lumped in together with Bianca and Trip, and even within those four that there should be general differences that should be outlined for how they function.
About Stephan being worthless, read the end of that sentence again: "as a developmental case that is. He doesn't have a storyline, so he doesn't have a reason to appear outside of the necessity to have Ash battle some more."
Amount of episodes has nothing to do with it, it's about how a character can activate growth in another character, which if you read the following argument, you'd have to comply with.
That's the big difference between Georgia, Burgundy and Stephan. Georgia and Burgundy exist to support the development of Iris and Cilan. They're foils of those two characters:
Iris: Dragon Master in training.
Georgia: Dragon Buster, characterwise forms a challenge to Iris her goal, that Iris will have to overcome through growth.
Cilan: Connoiseur A rank
Burgundy: Connoiseur C rank, characterwise forms a positioning point for Cilan to showcase how good he is.
Ash: A trainer wanting to become the best.
Stephan: A trainer wanting to become the best, characterwise is the same as Ash, and thus they are buddies and don't have a very interesting rivalry, think Ash&Ritchie.
See how Stephan doesn't necessarily form a jumping board for Ash as Georgia and Burgundy do? Stephan is just as much as a random trainer as Koharu is, even worse, he's more like Ash then she is, and that's why I don't think that he's that interesting at all. He has no impending storyline or anything, they had 5 episodes to give him one, but they didn't. Which is why I don't suspect him getting one any time soon.
The only story I can see him getting is wanting to battle Ash really badly (a faux suspended rivalry) in various tournaments, but never getting the chance to, only to finally get this chance in the Unova League, loose, and say: "Well, it was definitely worth the wait". That would end his storyline through structure, but it isn't one that is characterdriven, like Georgia's and Burgundy's..
So that's why he's not as interesting as Georgia:
- Georgia and Burgundy can make Iris'/Cilan's characters grow, while Stephan's character can't make Ash's character grow because he doesn't challenge Ash as a character, but only as another competitor.
Also, Stephan is a lot like Ursula in that respect if you'd follow my line of thought and the storyline I set up.
Stephan: He wants to rematch Ash, but doesn't get the chance until the very end. Character arc closes by a structural event, but he still loses.
Ursula: She wanted to prove that Dawn couldn't win by KO'ing pokemon, she got proven wrong in the end. Character arc closes by a structural event, but she still loses.
Ursula was a counterpoint to Dawn though, while Stephan isn't..
