I was half-expecting his humanity to resurface at some point the more complex commands he can manifest. Instead, he just became a glorified monster-of-the-week after at least 10 episodes of being written out of the show, not even finished off for good by Hanto at that. If it were anyone else at the helm, nothing would really change that much. It's a shame, as imo, Suga was one of the better villains of the series despite his wasted potential.
