Hmm, this case is beginning to get more interesting by the minute. I was sceptical at first, as I thought that each arc in Night Head Genesis would be full of hate and suffering, but the concept they used for this arc also worked out very nice.
First of all, the vision of Kamiya shows a bit more of itself. We have a golden elephant who flies away. Then we have a black glove, in which a silver snake appears. This snake dissolves into a flour-like substance.
Also, if the visions keep coming, this anime can do some very interesting things. I think it’s going to try and play with the future. As things stand now, the woman who attacked Naoya will kill someone other than Naoto, Naoya and Kurahashi and end up in jail. Naoya will end up touching someone and have the worst shock of his life, making him unable to recover. Then, an airplane disaster occurs in which a young pilot takes his parents along with him and afterwards, about fifteen, twenty years into the future, the disease will kill humanity. The question remains, how much of this will come true?
Remember the first prediction we saw from Kariya? Naoto and Naoya were looking at a street full of corpses. As this will happen about twenty years into the future, it has to be a symbol, instead of a realistic vision (just like the elephant and the snake). What if their own meddling was the actual reason for Kurahashi to develop the virus? Was it their meddling that caused Kurahashi to become nervous, and messing up so much that the virus was set loose? At the end of the episode, we also see Kurahashi’s assistant in a very unhealthy condition, dumping a few strange flour-like medicines and dropping them in the drinks he was supposed to be getting. What could it mean?
