Hah, I considered Usogui was bluffing, but I guess the wedge had been driven into my brain too, and figured he must have saved some to make it a double-layered plan. Impressive that Funeral Chief was able to see through it.
I knew he had a reason to drift to him. He needed to do something specific to Lalo as he dies, like he did with Q-Taro and Sadakuni. Though unlike with Sadakuni, where he wanted to make him die like a normal human, he wants Lalo to suffer.
Usogui truly is frightening.
