Botfly Misrepresentation

The botfly was badly represented in episode seven of season two. There was a lot I liked in this episode, especially the humor, but the way the botfly was portrayed with how it affects humans was completely incorrect. Bummer. Which also leads to some plot issues, and a few things left unexplained that even the iteration of the botfly in the show couldn't have been responsible for, e.g. the living darkness in the tunnels, the skeleton hallucination, etc. (perhaps that part was a genuine evil that'll be fleshed out in future episodes). But botflies are a single larvae in humans, and they do not make a spiral pattern as depicted in the show, at least as far as I know, and there wouldn't be a hoard of them bursting out. It's a bit disappointing. They almost should have made up a fictional parasitic fly.
