Dude, this chapter was so good, For real, I can't wait for Shadow Legendaries(Shadow Lugia or Mewtwo), but the part I personally liked the best was a little PoV of Ash's friends and I would love to hear from May and Dawn too and maybe a little something about Pink.
An idea would be for Ash to win the leagues, but not challenge the Elite 4. He'll save up his rights to challenge for each of region, then when he becomes the Alola champion, he fights all the Elite 4 (Kanto, then Johto, etc.)
