Well, then. Introductions! And I'll get to my sheet shortly.
Zen is a new member of the crew. She came on board with the current cargo, and is on hire from Vis-Ion. Not an altogether unusual arrangement, as large corporations usually try to have their own representative on board vessels with important cargo. Zen, however, is not so much an agent as a useful appliance. Her specialist areas are linguistic - she speaks the common galactic language, of course, but also the local tongue, which is different, and her presence will make things easier in that regard. She's a well-programmed pilot, and also has medical software. This means she can fly the ship when everyone else is in cryo-sleep, and also tend to their medical needs while they are asleep, to ensure their safety. She's completely conversant with all ship computer systems. So, left on her own, she could fly the ship to the drop off point in a crisis.
Like all androids, she looks human. But her body language and small signals that are entirely subliminal mean she does not FEEL human. Across a crowded room, you couldn't tell the difference. A few minutes conversation is enough to reveal the truth, though. And, again like all androids, her not-human-enough non-verbal signals make people get seriously creeped out.
As an example, think of the way Wednesday Addams behaves, and you've got a good handle on it. A smile that is not a smile. A gesture that is just a mite too slow, or too precise. Language that is perfecly acceptable - but also, just a little too cold and clinical.
Robophobia is a phenomenon that exists in both the works of Asimov, and in Doctor Who. I fully expect that it is a problem in some people who spend a lot of time locked up with androids.
You know. Just like you are, on this ship...
