Submas/PLA au idea but everything happens normally except Ingo has a shiny sneasel/sneasler that follows him around. Because the sneas’ mother, Lady Sneasler, rejected him bc of his different fur color, therefore leaving him to Ingo’s(and by extension Paulina’s and Akari’s/Rei’s) care.
Ingo then finds himself resonating with the sneas’ loneliness in that he(dubbed Sneaky the Sneasel) cannot interact with other sneasel, his litter-mates or not, due to his different fur color and therefore Sneaky cannot truly belong; in the same case of Ingo never truly fitting in due to his odd behaviors, his accent, his mental disorder of autism and the way he dresses. And that neither can actually interact with their siblings anymore
Ingo becomes the father he never thought himself to be due to Sneaky and the constant presence of Akari/Rei(they bring food for Sneaky and Ingo bc they love their old uncle)
Sneaky follows Ingo to Unova when he returns too. Emmet has many questions on why his brother was found in the middle of the forest with a ferally protective foreign pokemon protecting his unconscious body.
