Let's be realistic: When the series ends, the producers will: a)Leave us to come up with our own answers for all the little mysteries that there was never time to solve (ex. How Libby wound up in the nuthouse), or b)Start a series of novels, covering the material that was never covered in the show (a la Star Wars). Maybe both. I say, that if they do leave the mysteries to us, we should all get together (on this blog, of course) and come up with our own answers to the little mysteries, if only to satisfy our own rampant curiosities. For example, I recently decided that the Hostiles built the rope bridge, but eventually moved away from the area, leaving it to fall into disrepair until it was broken when Charlie stepped on it.
