From 2/2 Show thread:
Like Arielflies, the area around the skulls appeared to be a good place to start rooting around to me. How Misty arrived at that hairbrained notion of examining where she and her gal pals were standing is beyond me.
Considering that Jeff went out of his way indicating that the full water cask was something useless to her for drinking seeing as she lacked fire to boil the water, I'd begin with searching in and around it. Its hard to imagine future exiles having the foresight to bring a flint along with them, so the water will be useless to them as well, at least for safe drinking purposes.
I wonder if the others will come up amongst themselves with any kind of coordinated plan for searching the island so that people from the same tribe don't continually search the same ground, and if so, whether that is actually good. Could you trust something as significant as the immunity idol to the eyes of another?
