Shirley, his girlfriend, was born on an alien ship. She lived on Arret as a child until her parents returned to Mars. Now she's part of the crew but still has to prove herself. Women are still not appreciated on this backward planet. When she befriended one of the locals, Nathan wasn't happy about it. She wants to become independent but the culture toward women is far behind Earth's.
Alice, Mike, Gothur, ViTel, and Poppi still play important roles in this Quest series.
