Would've prefered it if Lillie and Mohn won't show up here because I simply would've liked Peony and Peonia to appear and have a plot episode more. Now this feels like they wanted to squeeze in that unnecessary Mohn plot they forgot about in SM in a Crown Tundra episode because what? Resolving a subplot three years late?
Why not having a seperate episode for that? Uff...
Well Peony and Peonia could still appear if they use them for the Dynamax Adventures plot.
With there being so many plots in the CT, they can definitely spread out which characters are involved.
Calyrex, Spectrier, Glastrier: The Aether Family
Regidrago and Regieleki: Goh and Gary, Project Mew
Dynamax Adventure: Peony, Peonia, and maybe Chairman Rose (he did escape)
Galarian Bird Trio: Team Rocket??
