Ooh, look, there are some people here! And they've all made me laugh already. So...yay them and all.
Now onto logistics...if I'm right (which I may well not be), there's only Shelob right now, and someone who will turn into a spider come Nightfall. (Unless she started out with a fully-fledged spider, and I think that was dependant on how many people. I'm guessing based on the numbers that it's a Bitten, not a Fledged - this may be wildly inaccurate.) If we kill the Bitten, would it show up as a spider, or as an innocent?
