I have just finished the final episode of SplaTOON 3: Side Order, and I like how it turned out. I thought at the start that it wasn't going to turn out as great as Octo Expansion did, but now I think it compares. The real breakthrough came in episode 10 when Monii realized that Order's motives were personal. I think that even covered up a plot hole in the game, that being "why doesn't Order grayscale them right away?" I'm also proud of being able to start every episode with Timo and Frye in the real-life apartment after I failed to include Dr. Etsu at the end of every episode of season 3 proper and continue with the running gag of Deep Cut unintentionally defiling everyone's bodies in Imagine Inkopolis.
This is the end of SplaTOON for the foreseeable future. However, I have more faith in Splatoon 4 coming out now than I did in Splatoon 3 coming out when I finished Octo Expansion. Who knows what adventures will occur in season 4 if/when it happens? Only time will tell. In the meantime, stay tuned for The Invisible World. I'm going to have a busy weekend, but I'll try my hardest to get it out on May 19!
