Ganja And Hess

I still have so many questions about this film, but I definitely see how what we would call "art" is portrayed in it. From the African chanting to the rest of the soundtracks, readings and symbols. I really liked Hess, because he was more of an isolated being than ganja, the more outgoing one. In the first part of the movie, I was confused with the names. I though Meda was Ganja and Hess was "Dr. Green" and not knowing his name was Hess. Why did she kill Archie? I think that because Hess died, she wanted to hide all the evidence along with the revival of "dinner man" as an immortal being.
