Wow I really didn't expect Charlotte to be the next gym leader. (Personally, I was almost certain that it would be Titania)
I had 2 Water types (Simipour & Greninja) but I couldn't beat Charlotte. Hence, I had to turn to the popular Rain Dance tactic - which I taught to my Meowstic. It was slower than her Typhlosion, but it managed to survive its Flamethrower (which was very surprising) - so the battle went smoothly from there (the extra boost to Noivern's Dragon Pulse and Florges's Moonblast actually helped a lot).
The fact that she did not have any healing items also helped (which was strange, because I was expecting a lot of those since its... Reborn lol). Was it like this for the other Double Battle gyms (Aya & Radomus)? I can't seem to remember...
Overall, a great episode as always. Thanks Ame!
PS I wish Saphira used a more uh... stronger(?) term than the 'world's biggest asshole' to describe Fern. Obviously, he's way more than that now.
