What if XY took the same path as Hoenn and Incorporated Sinnoh Battle Frontier since it was in Platinum but never showcased like Kanto's was. Want chance do you think Dawn would travel through Sinnoh with Ash again?
Do you know who is the battle tower tycoon ?
Who is son?
Who is childhood friend of Dawn's ?
She would know in no time and come running to see Ash again! ( along with my favorite blonde rival for Ash ).
