Finally got the chance to watch this episode. I will always miss you Poipole!! I was hoping for a scene before Ash and the rest entered utside of the Ultra Hole for Poipole to realize it didn't want to leave Ash but... it never happened. Poipole had so much potential to learn how to battle with Ash, to continue having fun, ticklish moments with it's friends, to forever view shining lights, but alas, as Ash put it best, "It's for the best." Sure it wasn't dreadfully emotional... it was a bittersweet kind of emotion, Poipole being the last of the Ultra Beasts. It knew it had to stay, Ash knew at some point, it'll have to stay, and in the end, even though Ash and Pikachu didn't want to say goodbye, no matter how hard it was to let go, Ash couldn't let his selfish desire stop it from changing it's final decision. You can say all you want about how Ash just dumped Poipole off without a care but no, it was heavily shown Ash didn't want to. From the way he barely showed his face, his hat covering it, the suppressed tears, how shaky he sounded... he didn't fully come to it until Poipole left him it's last message with a drawing of both him and Pikachu. Honestly, I think it's always hard for Ash to let go of his Pokémon no matter the circumstance. He just tries to show a brave face. Even though Poipole didn't do much, it wasn't about getting stronger, it was about connecting hearts, being with the people it chose, and discovering this unfamiliar, vast world it stumbled upon. Man did I love that quick sequence of the opening playing grouped together with Poipole's touching memories.
Other than that, moments like Kukui doing a Z move, Bewear literally moving the TRio away from them trying to snatch their Pokémon to ruin yet another beautiful scene (like earlier), and everyone doing the traditional hand pose together was nice to see. I thought it was adorable seeing Ash help Pikachu do the hand pose, and Olivia being emotional after the Manalo Festival (and Nanu commenting on it.) The battles were ok, I don't think they were the focus. The animation were spectacular and how the Radiant One was literally glowing throughout our screens were eye popping.
Goodbye Poipole. I hope we see you again.
