I didn't like this episode, like, at all. As in it's in my top 20 worst episodes of all time. That's for the very reason that the plot makes no sense. Sandy WOULD NOT abandon her friends out in the woods, she WOULD NOT let her friends starve, she WOULD NOT drive her friends to the brink of insanity and encourage cannibalism, she WOULD NOT sit back and do nothing as her friends potentially eat each other. If so, then she's a terrible friend. Oh yeah, and what was up with each character being extremely flanderized in this episode? I didn't like it in Spongehenge, and I didn't like it here. This is one of those episodes where I truly wonder what the writers were thinking when they wrote it.
