also just passing an idea along, but maybe a david 8 that has been rebuilt with parts from the derelict would be awesome. i think thats what will happen eventually to make the giger alien. white android blood and black alien goo... plus ash mimicking the alien's life cycle by using a makeshit proboscis on ripley. i think the giger alien is technological partially and thats why the engineer didnt freak out until it found out david 8 was an android.
anyway, yeah im a little more than obsessed with the ridley scott alien/prometheus aspect of that stuff. haha
