In Aliens 57 years have elapsed since Ripley left LV 426. During this time something like 200 terra-former colonists settled there, made it there home, yet never noticed or were disturbed by the 'alien eggs' in the derelict spaceship. Within days of Ripley being returned to civilisation, or a waking state, the signal from LV 426 cuts out. Why? It can only mean one thing. The alien intelligence has been waiting for Ripley, and that somehow they know she is ready again. They want her. Why? Did they find that only her DNA is somehow compatible with theirs? Is it Ripley herself that they want, or is it simply vengeance? They capture all the colonists bar one. Why did they leave Newt? Were the aliens careless? If they wanted to, they must have been able to kill a small girl too. Yet they leave one person who will arouse a maternal instinct in Ripley, bait in a special trap for Ripley. in Alien3 the alien kills Newt and Hicks, but saves Ripley to become the alien queen's mother -- why not pick Newt? Isn't Newt younger and stronger?
