Rewatched this episode recently in the dub and man is this episode the MOST UNDERRATED episode of JN, absolutely!!
The writing was so good here, the way they properly setup the episode and it's ending, how masterfully it adapted and added to the game lore into the anime, the bond it developed with flabebe in a short time, made the species of Pokemon so endearing and its release sad and most of all how well this episode was for Gohs character, making me love him so much more he's the sweetest!!! Such an underrated, well written beautiful episode
