Tim Post is the actor who portrayed the "Surly Belter Crewman", the one on the refugee ship who made sure Prax wasn't evacuated along with all the inner planet refugees. That didn't help the character "Doris Bourne", though.
- Character is not given a name. His space vessel isn't given a name on-screen either. His jumpsuit has a "Beltrans" logo on the back.
- The website Syfy.com names the ship, the Beltrans Jefferson Mays, after the actor who performs narration for the audiobook series, Jefferson Mays.
