Okay, now the part with the dragon in it. :-)
Enya wasn't in the best mood after the Grass Trial, 'k? So she didn't exactly take to it kindly when Professor Kukui showed up and dragged her back to Heahea City, that town on Akala where she couldn't get a room in Lillie's hotel. Well, now that she'd passed her Trials, she had access to more of the city than just the hotel and the Pokémon Center. But Kukui escorted her to the Dimensional Research Institute where his wife, Professor Burnett, and her team were studying the appearances of strange Pokémon(? ...No one was sure if they were Pokémon or something else entirely) from, apparently, another dimension, and that somehow Lillie and her little Cosmog seemed to have attracted their attention, and would Enya please familiarise herself with the situation and let them know if she saw anything?
She wanted nothing to do with being cooped up in a lab; she was tired and cranky and it was way past her bedtime, and you know how she gets on not enough rest!! And now the Alola Region knows it too. She only stayed long enough, read enough, and talked to enough people to meet the bare minimum for being allowed to leave the lab, whereupon she ducked into a Diglett tunnel, beat three Trainers and those Team Skull grunts again, and popped out in Konikoni Town, which was much more welcoming. There were shops and street vendors and !!!restaurants!!! (including Captain Mallow's; Enya got a serious 'friend discount') and a dock, plus the obligatory Pokémon Center and malasada shop. She bought stuff, sold stuff, learned stuff. And the reason she knew she had to be there was because that was the part of the island where she was to battle the Island Kahuna.
An interesting thing about the Kahuna battles: they're just...battles. No Totem Pokémon, no Island Guardians - just a good ol' knock-down-drag-out Pokémon battle. Okay, you're fighting the Trainer who raised the Totems, and all her regular 'mon are max-level final evos, no big deal...just a battle. Uh huh. And the Atlantic Ocean is just a body of water. Ayyup.
As it happened, Kahuna Olivia specialises in Rock Pokémon. Ohh, Enya had her number already! 'Cause her little Tiblet is a Rock-type, and she loves him to bits, so of course she knows what he can beat and what can beat him. If a move of a certain type would be bad for Tibbie, it'd be bad for Olivia's team too. So she brought Tayu (Grass), Pity-Kitty (Dark), Fletcher (Water), Tae Quon Lee (Fighting), Tron (Steel)...and good ol' Kilvana (Ground). You can see how this went, right? The biggest moments were when Olivia released a Midnight Lycanroc (the werewolf); when Tayu, taking a leaf from Totem Lurantis' book, learned the move Synthesize, after which nothing could keep him down either; and when Kilvana ended the nice, long, good fight by doing her li'l earthquake thing.

As part of her reward, Enya was granted the ability to summon a Charizard with her Pokémon Ride Pager. But before she flew off to parts known (he can only take her places she's already been), she bought a fire stone, fetched Pepper the Growlithe, and gave him his well-earned evolution into an Arcanine. I left her on the Lighthouse Point observation deck playing with her big puppy while a lady showed off her troupe of dancing Pikachus. :-)

Those Pokémon Professors: Personally, I think they're *all* a little loosely-connected between the head and shoulders... I mean, they've supposedly dedicated their lives to studying Pokémon. So how come they need sixth-graders to do all their field research? And if the profs are having people search for new species, that means they don't know those species exist, right? Yet when a kid finds a new Pokémon, his Pokédex pulls the data right up and tells him what it is! A real head-scratcher there. So, yeah, Kukui's a nice guy (did you know he sidelines as a masked wrestler? --Enya ran into him at the Royal Battle Dome!! She didn't recognise him, but her buddy Hau did), but he obviously doesn't know *jack* about the new Pokémon species called "a Enya", or he would've offered her dinner and a place to crash for the night lest he fall victim to all four of her attacks (Pouncewag, Astonish, Grapple, and Teh Cyoot). *fg*
And what's with those kids' parents, anyway?? For one, I've never seen a Trainer with a dad living at home. They all have single moms. And those moms, faced with the full responsibility for safeguarding the young'uns, are perfectly okay with their kids leaving school in fifth or sixth grade to go on a solo wildlife safari?
...Yeah, the Pokémon world has its peculiarities. It's just one of those things you accept in-universe and carry on. ;-)
