Don't Read this if you don't want me to ruin it for you. You already determined that. The phage was not some sort of new life form not based on carbon or water or whatever. So then your new alien friend that you meet is a spider. Why not make it a humanoid since we're already talking about familiar things? Because the phage idea was really good. But then you come along with a spider. Which is too hard to visualize in anything. So make it a big giant man. Make it a small man. Make it a you know weirdly fat man, something like that that makes it easier to process. It became too difficult to just listen to it and try to imagine this. Spider-Man with three-fingered triangular hands doing stuff. Totally lost me.
