Jeremy is a realist. He believes in what he can see and what can be empirically proven, but a string of events in his life cause him to falter in his skepticism. He wonders if the odd events in his life are somehow related or if it is just his mind making connections where there are none. Once he starts to seriously consider one scenario he would have once considered implausible it becomes hard for him to a draw the line between what is possible and what isn't.
