I like to imagine that the series continue on until the next millennium and these 10 year olds start greeting each other like frigging eldritch gods.
"Ah, it's you, old friend! Has it truly been a thousand years since last we fought?!"
So those are Satoshi's friends!I haven't seen you two in forever! You haven't changed a bit!Come on, now! That's rude!It seems like they're both gym leaders!You two are so cool!Man, how many years has it been since we've all gotten together like this?Hmm... it's been around 15 years, maybe?
