I haven't gotten to this part of the game yet but isn't it explained that he was admitted due to his incredible talent for handling Pokemon quite literally centuries ahead of everyone else? Or at the very least even if not directly explained it's highly suggested with how good he is relative to nearly every other character in the game, being 1 of 2 NPCs with a full team of 6So there was a little thing with Ingo in Legends Arceus that bugged me.
not that he was there, or that he was a faller or anything like that, just that they didn't go into any detail about the fact that he joined the Pearl Clan
That's kind of really notable and they don't talk about it at all. He's a stranger with amnesia, who probably appeared from nowhere (at BEST they saw him land from a wormhole) and strange clothes but they let him into their clan and he eventually became a Warden to one of the ten most sacred Pokemon in the land. That's...pretty substnatial amount of trust required on their part that they don't get into at all, in a game whose kinda-sorta theme is about trust and being open to other ideas. Iridia has to be convicned that the Balm thing would work at all, and is wary of us but what about Ingo? What was that process like?? And while the timeline of Ingo being here isn't reall laid out iirc I feel like he's had to have been around since before Galactic showed up 2 years prior.
Just a missed opportunity, I feel.
