Made some new screengrabs from the 1080p version - some new details and a possible reveal, so be warned
Remember Ash flipping all those swithes at his control station when they were on the Nostromo bridge. They are fliping switches here too
I think I can make out 2 engineer bodies lying in the rubble
This could be the place where something went wrong - it looks like a 'lab incident' with that urn overflow
Better look at the exploding head with humanoid features - not the jockey helmet itself
Fifield and what could be one of the snake things inside his helmet. Perhaps it explodes while inside
That looks like Vickers quarters in the background, turned inside out - notice the barstool. This must be aboard the lifeboat, considering that it has been rumored/confirmed that Vickers quarters are essentially part of the aft lifeboat. The Prometheus itself has been destroyed when this scene happens, me thinks.
The visitor... notice anything...?
Look at the helmet reflection - does it reveal the face outline of the visitor facing redshirt? Doesn't look human to me, but you be the judge...
Besides - new theory:Davids outcry 'They are leaving' + 'Earth'
could be him describing what he's watching when the hologram is playing aka the fleeing engineers. Did they actually come to Earth
after some horrible event went down, perhaps leaving dangerous parts of their technology behind on Earth to
quarantine it? Remember the prologue part with the human growing black veins, looking at his hand?
Could this explain the engineers reaction when he's facing humans aboard his ship? He might be thinking of us as an infected species that should never be allowed to leave Earth and when he realizes that that is exactly what we've done, he decides to go there and destroy us altogether?
PS: those pictograms could be a warning - not an invitation, mirroring the signal in Alien.
PS: watch the 1080p trailer to check out the scenes in greater detail. I don't wanna upload 1080 grabs because tinypic usually f*cks them large files up for me, they vanish etc...
