 How would you describe Captain Llud's character transformation across the entire Quest III journey?
In the last hours the star ahead had grown brighter by many magnitudes, and had changed its color from a dazzling blue through white to the normal yellow, of a GO sun. That was the Doppler effect as the star's radial velocity changed relative to the Quest III , as for forty hours the ship had decelerated. For the Quest III was coming home; the sun ahead was the Sun, whose rays had warmed their lives' beginning.

As the Quest III's fuel stores and the hope of success in man's mightiest venture had dwindled, so the strength had gone out of him. Weeks and months had passed for the Quest III in interstellar flight while years and decades had raced by on the home world.

 He was excited at first and became jaded over time.  He was consistently excited throughout because they found a new habitable planet early on in their mission.  His only priority was taking care of his family, so the mission's success/failure didn't really impact him much.  He was never really excited about his job, but he became excited at the thought of returning home.
