So they are going for an Ash and TR solo arc here. While this isn't a great time to put the other companions on hiatus, the dynamic with only Ash interacting with the new characters and environments made it a rather memorable episode.
I'm interested by the conversations going between Nanu, Giovanni and the TRio, wonder what they're setting up. I was disappointed we didn't see Jessie attempting Mimikium Z, hopefully next episode. Loved that super evil huddle the whole TR gang have though, even the Pokemon.
Bewear still hasn't caught onto their dupe. XD
Liked all the Pokemon interactions, Poipole being a nuisance again, the Alolan Meowth being unruly and cat-like (though there was at least a couple friendly ones in the bunch) and Torracat lounging around. They definitely aren't neglecting the personalities of Ash's team this series.
Nanu comes off as a more unique dynamic for a Kahuna, not antagonistic and mean outright like some of the Kanto gym leaders, but he seems to really not have interest in doing his job. Acerola seemingly goading Nanu into doing a battle was funny, see she has the helpful, mischievous little sister role with Ash, with Pikachu even protecting her from some loose projectile during the battle.
The loss is hit and miss, while Ash loses more due to a folly by his Pokemon again, it was more frustration from Lycanroc getting owned to begin with. Ash's emotional but contained reaction was a nice touch, while still being empathetic to Lycanroc after it wallows in guilt afterwards.
League confirmed, and Kiawe looks set to join. I'm actually hoping he gets a good use in the league. While he only has two Pokemon at the moment, I suppose he has plenty reserves at the farm if worst comes to worst, though I'm starting to wonder if SM is gonna be going on longer than expected.
