That is a good point. He certainly has no qualms about killing anyone, so the lack of rampant death in Camp is alarming. If he is not doing all this to lure Lunatic out, but rather because he thinks that I am Lunatic...

To be honest, I can't blame him. I've never stopped to consider my own position in all this before now, but I would be suspicious of myself as well. I certainly do qualify for some of the characteristics of his profile. The only question then would be why Hisoka has thought this for so long. I would assume that someone like him would be able to tell if I were Lunatic or not after one encounter.
