There's also a scene showing them exiting the Space Jockey's ship. She is lowering Davids body on a cable, and is talking philosophy with his head (for the benefit of the audience really, she shouldn't be so calm with him, after he killed her boyfriend, surely?)
He asks why she wants to go find more os the engineers, and she says' they made us, then changed their minds. I deserve to know why'
David says this is irrelevant.
Shaw says, its relevant to her because she's human, and he's just a robot.
There's another light hearted moment (again I think inappropriate) where she is putting his head in a bag as she prepares to abseil down. She's zipping it up and says "sorry" in her annoying meek voice, and he says he doesn't mind, as the bag closes on his face. This gets a giggle in the audience from some people, but I thought it was ridiculous considering how she should be feeling about this cold untrustworthy killer.
We then get treated to hearing Shaw record a log "as last survivor of the Prometheus" in a poor rip off of Ripleys "Last survivor of the Nostromo" where she tells us it's New Years Day, (so about 5 days seem to have passed that we know nothing about - where they may be prepping a ship for launch etc) and she waffles on in a meek voice, absent a hard egde in its tone, about going on to find things out.
THEN we cut to the lifeboat, where the giant facehugger thing that was lying on the dead spacejockey (almost entirely covering him, if you recall) has conveniently disappeared, giving us a clear view of his chest being ripped open, but not by a small chestburster as seen in every other film, but by an Alien with fully formed limbs abotu 5 foot high, differing from the ones were used to, it doesn't have the very prominent 'tubes' on it's back and it's head is tapered to a point at the back, and it has a second set of jaws, slightly smaller than the first, as opposed to the long extendible, penile tongue with smaller knashing teeth at the end. of it.
Roll credits.
