Is Cthulu a god-figure of some sort? The name itself could very well be a reference to our favorite green-tentacled monster deity (and no, not the Kraken). Plus, he is seen all around the island (referenced by Curly Brace in her mode to be the same person) moving inexplicably fast, and containing key information at all points. Could he be guiding Quote to try and save the island not only from the Doctor, but from Ballos? Or am I just over-analyzing. Anywho, he is one of my favorite minor characters... if he is minor.
