 Which of these is the best representation of the connection between Old Dunbar and the rest of the crew?
Dunbar, the oldest of the four, an old space-buster with a face wrinkled like a dried prune, burned by cosmic rays and the suns of worlds so far away they were scarcely credible, had taken command. Four men, thought Russell, held together by an invisible string of gravity, plunging through a lost pocket of hell's dark where there had never been any sound or life, with old Dunbar the first in line, taking the lead because he was older and knew where he was and where he was going. When the four of them had escaped from that prison colony on a sizzling hot asteroid rock in the Ronlwhyn system, that wasn't enough for Dunbar.
 He led the group out of their previous lives
 He tagged along when they escaped their previous situation  They are all former members of the military on equal footing  He led the group out of their previous lives  He thinks he is in charge but does not call any of the shots in reality
