An inner voice is an element of the unique nature of what makes us all different. For whatever reason, some have this and some do not. Eddie and Darren don't have the answer as to why some have it, but this is a discussion about it. One key function to inner voice, is the idea of drafting a question or statement. Narration or private conversation, is another way this inner voice is used. Often, it is just saying what is happening or about to happen in the head of the individual. Some people that do not have an innervoice think with imagery rather than a dialog. Talking to themselves in their head, is possible but very difficult and not second nature. As often the course, the rabbit trail turns into things that bother Eddie or Darren.
