Yeah, that season end felt rushed. It's also ridiculous that 'fatty' just keeps running away like that (whether it's justified in the story or not, it's maddening to just see him go Team Rocket on them 2 times in a row).
It's also really not clear why the elder-brother had to die? The villains did force some form of poison on him to better control him, but the narrative just describes how the MC's attack wrecked him. Surely that's a touch ridiculous? The brother wasn't even on-scene at all during the battle. They really tried to rush a form of conclusion here without really conveying the finer details better.
Well, whatever. This was a skim-read type of story for a long time now, I guess? Cya in a few months. :u
