Yeah, it's not complex...it's sneaky...but not complex. I liked the explanation of it as a quadriplegic in the book. It has no motor skills and can only rely on the power of persuasion on it's caretaker. It's essentially powerless unless it successfully talks the "I" into doing something. As long as the "I" knows it's the "it" speaking, all "it" can do is sit there and pout.
