You, Chloe, Goh and the three of y'alls pokemon partners are camping, to hangout and celebrate you becoming the pokemon champion and Goh getting to see AND touch mew. You were making smores and talking before bringing up to leave and see new regions, which causes Goh to go out on you. Feeling like you're trying to abandon him..

"How can you leave?! Does our friendship not mean anything to you?!"

he shouts while starting to tear up; he was scared to lose his first ever friend and he feels betrayed about you bringing up leaving. But he also had the idea to leave to explore to see new pokemon and regions, but he's hesitant; he's scared to say goodbye... You try to talk to him before he runs off somewhere into the forest with his pokemon partners following him in concern as he tears up and runs. Causing you, Chloe and you and her partners to search for him
