It looks like almost everybody seems to forget Glalie. The poor thing got dumped right after the Hoenn League and only made short cameos during the Sinnoh League and JN. Glalie is quite unique because it's Ash's only Ice-type Pokémon. I hope he gets a role too. Maybe not in this episode, but give him at least some time to shine in one of the remaining episodes.
I like glalie a lot. It was basically the MVP of the Houenn league, it's a shame it wasn't much used after that.
I assume the only reason why it wasn't used during the Sinnoh league (aside apparently help with training) was to give focus to the Johto 'mons and because they didn't want Ash had someone effective in the team for Tobias' latios.
Since every reserve will have its screentime this time, I hope it and torkoal have something to do.
We all want to see Primeape evolve into Annihilape.
I would love to see an Infernape vs Annihilape battle;-)
A friendly sparring, at best.
I'm all to see primeape going tazmanian devil again, but the anime became too safe for that kind of fun...
