I really liked this episode and Volkner + Flint as characters, again getting to know more of the Gym Leaders/E4 and who they are as people is something DP does exceptionally well. Their backstory together was quite touching, as well as the way we see Volkner eventually drifting off and becoming more detached and apathetic. Burnout from not being stimulated or challenged is real, and I think it was portrayed well here. Volker then being revitalized by seeing Ash and Flint fight and seeing himself in Ash was great. I just love Volker, I think he’s so cool. His design, his story, his team, his association with his city; easily the best Sinnoh GL.
Sunnyshore is such an awesome city, it’s still one of my favorites out of any region. A seaside town that runs on electricity from solar panels? Just so unique and very aesthetically nice to look at. I always love beach towns and routes in Pokémon because I have an affinity for those places irl, but Sunnyshore feels distinct in the way it melds together technology w nature.
