The real differences are here in the future!"verse"
Iris is twenty six, a mother, and actually marginally more mentally stable now
Diantha, his auntie is forty, no longer a champion - and is now free to watch over and nurture her successor
Thyra has turned down the position of Acting Galar champion - now twenty two and and pursuing a career in architecture over professional battling.
Drasna, now eighty four is finally retired - but can't seem to extricate herself from the league, occasionally visiting to keep a eye on the next generation when she's not tending to her bookstore.
Calem however? He's still fifteen, physically at least. His mind is that of a twenty year old adult, but he's frozen in time as some godforsaken fae creature doomed to not actually look his age til he's eighty. He just wants to stop getting id'd buying cold meds. It's very hard for him to socialise with people his own age because he still looks like a fifteen year old boy.
