Fear is a natural reaction to moving closer to the truth, or watching the guy next to you being ripped to shreds by a bug
Zhang is cool 80-year-old guy that joined the crew so he could see space before he died. He is filled with ancient Chinese wisdom and the only cybernetics expert in the game; can build androids. However the trade-off for this skill is that he's incredibly slow to move and requires a lot of sleep.
Psychiatrist's report: He is a sour and begrudging old man. He wanted to see space before he died. Some colonists are wondering when that will be.
Venus' description: Old Zhang is the cybernetics king. Without him we would never get any androids made. He is incredibly intelligent and doesn't believe the hype, he is actually a really nice guy underneath it all!
