Hikari/Dawn's return was so adorable. It was really cute how she sneaked up on Satoshi/Ash and then they had one of their classic high touch/high five scenes.
SO cute. <3
It's really not about the battle, even if the title focuses on that. It's more about Satoshi and his new travelling companions meeting Hikari again.
Pochama and Mijumaru's rivalry, in love and otherwise, is very amusing.
