This episode marks Iwane's 4th solo XYZ episode of the year, a mere two weeks after his last one (#27 on May 19th), and only six weeks after the one before that (#23 on April 21st).

I wonder if this is because he is also working on the movie? Either way, this and Episode #23 have been some of his best work in a while. I can't imagine he'll be able to pull this off again for the Kalos League, which starts with Episode #32. Then again, maybe the League will last until #37 and he can do the final episode like he did with the Isshu League?
