What I want to see happen regarding this N chapter is that Meowth becomes a competent battler. As well as have the trio catch something on the lines of Houndour, Poochyena, Octillery, Huntail, Roselia, and James' Growlithe be apart of James' Team.
Regarding Ash and the gang.
Ash - Zekrom befriends him after Charizard gets hurt and can't fly.
Iris - Flygon or something Dragon related
Cilan - Duskull
Zekrom appears after he learns Reshiram has befriended N in his quest to stop team Plasma who has Kyurem. Charizard appears after Ash is shown on tv in the Unova league and goes with him to the White Tree Hollow to battle and train there like a battle tower.
In a battle Ash calls upon his Charizard vs. a trainers Salamence becomes victorious in the tower. N shows up saying he needs help to find Reshiram in the White Ruins. Ash and co. agree to it along the way Team Plasma disrupts their travels on the path to the White ruins so N has no choice but to battle through his way using his trusty Zoroark and Klingklang through Team Plasma grunts.
