Things aren't really that vague in the show, rather, they release information in bits at a time, because let's face it, it's a lot to take in. From the pilot until now, the viewer starts at ignorant as Nick did, and learn more and more with each episode (adventure). With as many as are out now, and as much lore the show revolves around (a lot of it intentionally obscured), it's easy to get carried away.

My point is, a lot of people like to throw out what-if scenarios that connect to nothing that's been revealed or learned throughout the course of the show, and that tends to do little more than lead people astray from the facts as they're presented in the episode. Certainly, there's a lot left to speculation and individual intepretation, and maybe this was intentional by the writers. At the same time, though, there is a lot of dots that can be easily connected by taking the bits and pieces given in the episodes and simply putting them together.
