scott or chloe would be my choice
Are we talking about main characters or anybody on Destiny? If it were main, I would have to say Rush. He's pretty full of himself, however, I would need him to run the ship. As for anybody else on Destiny, I'd go with Morrison. He's kind of an ass and would ruin a good time.
Camille , when you think about it she is pretty useless when it comes to running the ship . The only things she has to contribute is complaints and treachery.
I wouldn't throw anyone off. The crew is so small and everyone is necessary for survival. You have to value your people in a desperate situation.
