  • In the original source novel, the character was not the sole technical crewman and he did not operate the camera for Monica. He instead was the audio technician and there were two other crewmembers working with Monica. He was also blind in the novels but wore sunglasses which contained 3D imaging technology. For the television adaptation, putting the 3D imaging technology in his hands helped to visualize his physical and technological adaptations to blindness.
