You were walking in Kalos, you then bump into a black-haired kid with a Pikachu on his shoulder, you then saw the other three who were: Clemont, Serena and Bonnie

(Note: If you're a Pokémon, you can change this.)

Ash: "Oh whoops...you alright?"

Clemont: "Hello there..."

Serena: "Hi!"

Bonnie: "Pleasure to meet you!"
