Newt could decide to head off to college as Ripley had wished in a full resolution. Alternatively, she could head off in an unregistered ship. The President could (in the novelization;) issue a full pardon to the crew for all crimes related to the seizing of the Sulaco and vow that the government won't try to recover the ship. Maybe both. She goes off with the corporal on his G.I. Bill and the surviving crew takes care of the ship.;)
The other android is an ambiguous and ambivalent character. We don't know which way it's going to turn. It interprets it's basic imperatives in it's own questionable way. Robot means slave. Shades of ST, SW, AI, IR....
For interest in the colony, there could be a political divide. On the one side is the Libertarian sort of colonists backed by the company sponsored government as long as all are kept dependent on the company store, on the other are some Neo-Marxists fed up with it. Both sides make some good points and both represent grave errors. The Libertarians look the other way from company abuses and drugs and prostitution surrounding their families for the sake of their "get away from it all" ideology. The Neo-Marxists want to tear down without thinking about what would enevitably follow as going that way produces a horrifying totalitarian machine dedicated to stamping out any deviation from the central plan. The libertarians are too trusting of the company. The N-Ms hate the company and militarism and try to believe that it's possible to live in peace with any system. They admire the Marxist nature of the hive and try to make peace and co-exist.
Of course, every message must serve the story and never the story serve the message. Popular entertainment and all that. :)
Edit: Yeah, uncluttered and haunting is probably best. I'm a little anxious that everything be easily understood;) Newt could be encouraged to denounce them in order to finally protect herself. There's the same problem Cameron faced with prologue. Drop in ALIEN style? More time to establish the situation before introducing the Great Dilemma?
Edit: As has been pointed out around here, the passage of time is relative with stasis pods. Newt might be kept in hibernation longer than the others who must tend to the ship and problems.
Edit: Yeah, get things up front and let the audience connect the dots. It might look like they will be allowed to stay with the ship. Once the first wave of refugees are on with the authorities they could be arrested. A message was sent ahead and they have an agreement that Newt will run the ship and denounce them in a witness statement now that she is 18 (the bitch;) An arguement with Ripley cutting things off and they go down in shackles where they have to earn their release? They would have to be away from a place where they could just jump ship when they get the call.
Ripley nukes the derelect from orbit?
