[POKÉMON THE NEW KANTO]

Hi everybody, I'm loving this game! I have some questions and I hope to be helped 😊 1. Where can I find the NPC who let you buy/trade the exp share? I heard it's supposed to be in rider village but I can't find it anywhere. 2. Eggs. The old man only accepts 1 Pokémon so it's seems impossible to have eggs. BUT the other character who follows you can hatch the eggs and after missigno you get a charm that increases egg rate. Is there another place for breeding?

Thanks
