If you had a chance to end Pokemon xy & z series,how would you end it?

I would have Ash convince Serena to stay with him, and be his girlfriend (she kissed him after all, I mean he can't be THAT dense) then have them stay in kalos and have ash become an elite four member, or maybe champ(probably not). AND KEEP GRENINJA!!

Have Ash and all of his friends from every region go to Alola together.
