Rain would be "Hypotonic". No clue if KC is going this route, but it has merit. However, like everything KC does it is complicated. Once whatever it is gets into the bloodstream, it does a hell of a job getting out of the blood and hiding. Tanya has not been able to find it in the blood directly. K18 is a byproduct and Kimmet said the only way to detect it was autopsy. Sounds like it hides out in the brain...
