Fifield Finds Chest Burst Engineer

Chestbursters?

SPOILERS - Possibly. I think the scenario here is that this was a weapons development site which 2000 years previous the Aliens got loose and destroyed their masters. At some time after that the Engineers rescued the situation and brought it under control. A lone Engineer was then stationed on the planet after everything was locked down.

I think that the aliens did infected the engineers before they took off For earth. But after 2000 years, the Adult aliens might starved to death and didnt find new living host, as the remaining survivor was locked and sealed in the starmap room.

I wouldn't be inclined to go with the idea that there was a second crew who dealt with the outburst of chestbusters. Why would they then leave a pile of dead Space Jockeys blocking a doorway? It begs the question, thought, what happened the chestbursters, did someone who was mortally wounded, activate a control that neutralised them (did they revert to a less harmful state? ) before dying? Or, were they lurking somewhere in hibernation (remember, they seem perfectly capable of hibernating for a long time, but 2,000 years might be too long... ) or lying dead, in some part of the ship or tunnels that the Prometheus crew didn't get to? As for the sole survivor, I have a theory, that stems from watching the hologram replay. At least 3, and I think 4 Space Jockeys come to the bridge, and one activates controls, showing navigation to various planets including Earth. We hear them chattering , probably briefing about their mission to bring horrible death and destruction to these worlds, and then one stays while the others leave the bridge. He seems to be preparing for hypersleep. What I'd deduce from that, is that his part in the mission is limited to pilot and navigator, while the other three are overseeing the bioweapons experiments, being carried out by the dozens of space jockeys later seen piled up at the door. This is the reason that one guy survived. He was behind a big door asleep, probably completely unaware his crew was dead, until David woke him up.

@Hadley's Hope- Very good! That is a very good explanation why the SJ behaved so violently towards the human, waking up after a long cryogenic sleep to humans milling about their space. It would appear as if we killed the Jockeys to the surviving Jockey. Good show!

@Hadley's Hope - Much Agreed! I still am curious about where the hell the creatures are that killed the other SJ's. I seriously doubt they starved... I mean it's possible, but they are making a reference to the Xeno's with the chestbursted corpses... and I don't think our xeno-friends or their early relatives needed food to survive, but who knows? 2,000 years IS a long time...
