Usual caveats apply. In the show so far, Cordyceps is treaded almost as a conscious foe. The idea that a fungus which has evolved to affect the behaviour of insects over untold millennia can suddenly and immediately mutate to turn a human being into a zombie infection machine is just silly. We have many orders of magnitude more neurons than than insects so such a change would be utterly impossible. I get it, though, it's only fiction. I prefer a bit more logic. For Episode 3, as nice a story as it was, those couple of guys had one hell of a good life with apparently endless energy for hot water, light and heating for a couple of decade, not to mention all the wine. And plenty of food with little apparent effort required, either. Ah well, I suppose if the dystopian governments in their walled cities can manage to feed everyone, I can't complain about a couple of gay guys in their own self-built compound being able to do so.
