Also I want to call this out now that the guy in charge of Fuga is FULL OF FUCKING SHIT!!!

There is no way he planned to bring back Blutwurst since Fuga 1. Blutwurst was never used to tell a "human story" Blut was given zero lore to show any kind of struggle with his humanity. In fact he was utterly devoid of humanity. Fucking Flam had more humanity in that she at least admitted to killing Jins dad and wanted to turn herself in and showing some sympathy to Jin. Blutwurst just acted like an angry sperg for the 2 games he was in.

That guy is full of shit, and he only used Blutwurst because he either ran out of time to finish the game so he just fished out the only Game 1 enemy he had not reused for something and just called it a day.
