So having read some stuff about the Whispers and briefly watching over some of the old footage I had an idea that I hadn't seen posted here yet about them. I'm thinking that perhaps the Whispers are in fact a monster like the Smoke Monster, the difference being that you can see the Smoke Monster. In other words, there exists a Whisper Monster that exists as one discrete entity rather than thinking of the Whispers as a nebulous collection of many individual whispers. It comes up on people like Smokie does and makes some noise (the Whispers themselves) but rather than judging and killing them it seems to just simply guide them. Additionally, if you give it some serious thought, it isn't a far stretch from there to perhaps the idea that if the Whispers are indeed a Whisper Monster that perhaps the Whisper Monster is/is controlled by Jacob (that is, if you are one of those who thinks that Smokie is/is controlled by Nemesis). Just a thought.
