I've missed a lot of the XY&Z episodes (currently watching pre-League ones that sound interesting), so this episode was quite helpful for me since it seems to re-clarify everyone's position in the story.
I feel bad for Pikachu every time they bring up Satoshi & Gekkouga's deep bond. After 6 regions the climax of the entire XY&Z story revolves around Satoshi's deep bond with his Pokémon and Pikachu isn't the focus. Oh well. (warning: only 1.5 years into my Japanese studies!) Platane has found an old document detailing a similar situation in the past called a "bond phenomenon." It happens when a trainer and their Pokémon are extremely close. It seems to be related to a Pokémon's latent potential and Gekkouga possibly felt this when he chose Satoshi as his trainer and Satoshi eventually drew it out. Platane also seems to think their meeting was inevitable. It seems to be the kind of story you'd expect here to be honest.
If I remember right Shota was sad at his run in the league having finished but was grateful for the experience he gained and it was his first time having that much fun in a fight. I really like this guy, I hope we get to see him again some day (like how we saw lots of previous characters in this series?
)
Manon seems torn up on the inside and seems to have planted herself firmly in the middle of all of this, now having some sort of small relationship to pretty much every major character. Things are looking good for Hari-san though!
Alan seems like he might be feeling a little empty on the inside. Malva asks him what he's going to do after he saves Harimaron, and promptly responds with a defensive "it's got nothing to do with you." He's got his eyes focused solely on gathering mega evolution energy.
Nothing much going on with Team Rocket. They're simply asked to go back to work so they can scream commentary over the next two weeks, I guess.
Lysandre is doing his whole "I'm a good person and I want to do good things
" thing with Satoshi. Satoshi told him about the Gekkouga thing he learned earlier and Lysandre said he wanted to talk about it more after the league is finished and then wished him luck in the finals. Naturally this is going to involve Gekkouga spewing out tons of a certain type of energy, so you know...
Overall great episode and I can't wait for the finals next week.
