In terms of my the Pokémon Region I'm building, it's been very much my own thing, however I do have characters that have interacted with friend's OCs and know of the Region(s) they are from.

In terms of Arknights and Jasper, she wants to be pals with the other Docs that are aboard Rhodes, just needs that push to interact with them more than a wave or nod passing in the halls. Though, some of them she has interacted with on more than one occasion and hold those newer memories close.
