Re: Not to beat a deceased equine into the ground . . . Which is? Sorry, I'm kinda dense here.
No problem, I'm a little sleep-deprived myself. As for Vincent's relationship with Chaos: They are both not-human, but not because of what they are -- they were both equally dehumanized by Hojo.
That would be one pissed-off demon, I suspect.
Also, I'm going by the Omega Reports that suggest that Chaos isn't a demon so much as a planetary elemental, an intelligent life-form created by the planet and having a specific job to do. The demonic seeming of Chaos I ascribe to the experiments that trapped him inside Vincent with gods-know-how-many other beings, none of whom wanted to be there.
How very, very true! And thank you for writing this.
