I'm pleased that this didn't end in yet another down-to-the-wire stand-off, which has been the norm for gym battles since god knows how long. Of course, I'm sure it'll be a pattern they'll no doubt go back to for the majority, if not all, of the remaining gyms, so it's nice to know they could at least do it once.
Does this not also mark Ash's first perfect victory, bar the silly 'overload' crap from Pikachu's corner? I can't even remember a battle using more than one pokémon in which he came out victor with a reserve or two left over.
Buoysel and the Woahmeister have had far too much screentime at this point, so after this victory, I think it would be wise to have them take a backseat for a little while. Let Hiko get a gym win and show off a bit more personallity, have Glion win more people over with it's antics, and of course, more Muku.NONSENSE.
