There's no plot progression in that episode... Characterization can happen in plot episodes...Ah that's fine. I definitely understand why people wouldn't want that
That episode at least did give Lucario and Cinderace some much needed characterization (also I just really miss Cinderace....)
In Journeys the Pokémon are only allowed to have some degree of focus if they are A) Being captured by Goh, B) Showcasing that the species exists as an actual thing, C) Showcasing some alternate form such as Mega or Dyna, D) Battling or E) Evolving to showcase it's evolutionary lines.
They're not allowed to be characters anymore. That one episode felt like a bizarre outliner
It makes me worried immensely about the fate of the next Generation Pokemon
Writers fault... They've been failing in this series...
