David obviously came up with a way to neutralize the acidic blood of the face hugger and some of the other neomorph variations he has on display. They look like he has come up with some form of plastination to preserve them.

More of a pose than sculpture, but he is definitely into drawing and displaying strange looking dead dead things.

he has in a way created a sculpture of michaelangelos david using a dead engineer

That is the only photo I have found of it. A section David sawed out of two Engineers that melded together after the pathogen bombing? It has a similar look to the deformed bodies that were outside.

I suppose it could be a sculpture David made, although I do not see any other sculptures in the lab.

EDIT - if you look at the photo underneath the one of Ridley above, you can see it in the background, to the left of the guy in the photo.

Eaten like Parker. *chunk*

looks like a sculpture by david perhaps

I get the fact that spaights wrote a good script but he did not write the final script that made it to film. thus his script cant be taken as factual. the blu ray extras though have been entered into the alien universe by fox themselves thus can be taken as factual. the company are aware of the signal from lv426 yet the decision is made to go to lv223 first as it is believed it would pose less of a threat yet would wield fewer rewards.

Ripley “Dallas, please say again….”

Dallas, very garbled, “....A door... closed on us…. Didn’t ...see it when w..e.... entered…don’t see how to open it…”

Ripley “Copy that Dallas.","Is there another way out?”

Dallas “......uuh......yeah...will look... around…”

Ripley “Ash, how’s their oxygen?”

Ash “35 hours”

Parker “So you sayin’ they’re trapped!?”

Ripley “Looks like it”

…..

Dallas “Kane, do you see another door?

Kane offered, “No, this hole in the floor, maybe we...”

Dallas interrupted him, “ Rather not go lower, if we can help it…Lambert you see anything?”

Suddenly, just ahead of Dallas, a human form appeared.

“Hello”, spoke the humanoid, “My name is David and these are my friends.”  From behind him, two large creatures revealed themselves.

David signaled the creatures ‘spare the female’,  and added for all to hear, “Our transport has arrived.”

Unable to move, Dallas was eviscerated. The second creature slid past the screaming Lambert and pounced on Kane. David then tossed a small device, It exploded in a blinding display of light.

Lambert ” Ripley! Ther…”

….

Ripley “Lambert?! Please repeat! Lambert?...Dallas, Kane do you copy!?...”

Nothing but static greeted them.

Ripley  “Ash meet me at the airlock! We are going after them.”

Ash “Ripley, do you think that is wise?”

Ripley ignoring him,  “Parker, get this goddamned ship ready to fly by the time we get back!”

Parker nodded, for once, unable to say anything.

Ripley “Ash!? Are you with me?”

Ash paused, the added “Yes.”

Love to see a Ripley versus David. With a wild card of Ash!

So there is extra material kept back. A base on Phobos? I hope this story is a long one. :) How many extra stories do they have?

Kethol - Amazing pics !!!!

The last one is most interesting after a first glance through. Looks like a hand on his head. Also reminds me of Prometheus and the head they find which ends up exploding.

Anyone got anything on this last pic with the dual head ?

That looks awesome! Sign me up!

Thanks for sharing, upvoted.

...and a few more already posted here, but brightened.

I posted last year a theory I hade about the events on lv223 2 thousands years ago. I theorised that the elders or higher beings came to punish those on lv223 by planting xenos/ eggs close to the facility. on one of those ships in orbit one got loose and the result was the derelict. it was abandoned due to the others knowing the danger within the ship and we got a bit more insight into a possible civil war within the engineer society. there r endless possibilities open to fox and RS to explore. lets just hope they explore some of them and give us a film that does the original 1979 alien justice

ali81 ----

'I just find hard to accept is david being responsible for the fate of the derelict.'

As for the present situation, you don't have to accept that possibility because we do not know anything about the events of the movie(s) to come. It is possible that David is not responsible for the fate of the Derelict. The filmmakers can solve that problem with the help of many other creative ideas.

'who is to say the 1979 xeno is not an engineer creation?'

It is probable that the 1979 is not an Engineer creation, but you are right, it can't be claimed that it is not or it is made by David. I think other possibilities can enter the picture as well, for example, somebody or something we have not seen: creators of the Engineers, ancient androids made by the Engineers, another unknown alien species, etc...

'id much rather have the derelict land on lv426 thousands of years ago'

No problem with your point of view, totally understandable, and I think it is shared by Scott's idea since he mentions something similar in the interview in my previous comment: Scott: 'That ship happened to be a brother to the ship that you see that comes out of the ground at the end. They are roughly of the same period give or take a couple hundred years, right?'

So it can mean that the Derelict landed on LV-426 when the LV-223 Engineers jumped into their cryo-chambers - thousands of years ago. (Around two thousand years ago...)

However, it is probable that the makers of the next movie won't find that version interesting enough and create something much more exciting. :) For instance, there are more alien ships on that moon, or there is a hidden underground base we haven't seen yet, and so on... Endless possibilities...

They must make a good movie!

from what ripley says in alien3, ''if they send anyone out itl be, here, where the meat is'' imo implying that the xeno know where they r at all times. so if this is true, would the neo be able to surprise the xeno? from what I have heard about the book it says that the neo stalks the crew to the citadel so there is definitely a conscious mind set within the neo and not just pure animalistic traits. id say from what iv seen the neo would find it very difficult to sneak up on the xeno. in ways of attack both r very similar with tails, strength, jaws and claws so it would probably come down to strength in defence. which would have the greater strength in hand to hand. which would manage to ground the other and gain the ontop advantage. I believe the xeno is more methodical in what it does and given its harder outer shell id say it could take at least 1 attack to a non vital area without it troubling the xeno so I could take a calculated risk and allow the neo to gain a strike to enable the xeno to gain a strategic positional advantage. the neo being more fleshy simply cant take the same amount of punishment.

in short id have to back the xeno

would depend on the effect of the enzyme used in the morphing process. such as in the event that the victim had bot been immobilised by cocooning, would the enzyme contain something that would do this on its own? if so, would it have some form of anaesthetic or muscle relaxant to immobilise the victim?

I can accept that david messes about with the mutagen and creates something different to the original engineer design but what I just find hard to accept is david being responsible for the fate of the derelict. who is to say the 1979 xeno is not an engineer creation? id much rather have the derelict land on lv426 thousands of years ago as first implied and have it tie into the events of lv223.

u may be right but id suggest its been an oversight by the engineers when designing the substance. I think the basic purpose of the weapon was simply to wipe out the indigenous species and not interact and affect plant life but when the spores r disturbed it looks more like a fungus than plant and fungi are neither classed as plant life or organic so the engineers may have over looked the effect on fungi. so in a way u could very well be onto something, its just that its fungi that causes the mutation to the substance.

because the plant caused it to mutate to use it as a defense mechanism, and how better to defend ones self than prevent any potential further harm by basically creating an army

this where it gets complicated. on one hand the substance inside the ampules, when released, kills all the engineers on contact but leaves plant life intact which makes sense. the engineers wanted to kill what ever species inhabited the planet but not leave the planet damaged. so why does the mote, if it is indeed the same substance/ organic organism, that came out the ampules not just kill the 2 crew members and instead react in a completely different manner?

@Sherris 

Point Perfectly made.

The worst part of the Space Jockey saga for me is the fact that had RS left it alone after Prometheus then we could of all accepted that it was an Engineer, probably related to the LV 223 bio weapons testing and it crashed nearby on LV 426.

Job done. Now move on to the next thing....

Most of us would accept that and we move on to another question in the next instalment.

Now that can not be the case as David is the creator of the 1979 Xeno. So now that answer we had from Prometheus is now back to a question.

Simply can not be the answer as the Engineers did not have a 1979 Xeno as their end product. They had something similar.

What ? That is another question we now have.

if planet 4 is lv426 then why no mention of the Prometheus crew? they r aware of that mission and the company would have lv223,lv426 and the gas giant in their stellar maps and records. planet 4 is a totally unknown planet to them and if planet 4 was lv426 then the covenant crew would have certainly talked about the mission to lv223 as the 2 moons orbit the same gas giant but there is no such topic raised so they cant possibly be the same.

@BD

I must say I admire you for thinking that after the narrowing of Covenant to a mad robot who created the creature film you believe he is going to reintroduce all the elements that made Prometheus such a fascinating film. Most people who love the though provoking non spoon fed nature of Prometheus have probably jumped ship at least my friends have not even bothered to see Covenant as Prometheus fans. So to return to the broad creation story seems frankly daft after ditching it for Covenant.

Where did the ALIEN pathogen originate LV 223.

Who created the ALIEN - David

Whose the Space Jockey ..... 

Oh hold on a minute lets dump the beast thats cooked lets spend two more movies deepening the Engineer mythos and their role in creation having completely ignored them other than texture for a whole movie.

There is holding on to pre conceived ideas that are important to us through the momentum built up on previous movies and then there is the real likelihood of something happening and I really think anything that goes in the next movie is to serve Davids story and get us to where the Jockey is and thats it. 

I have no idea at all how the backing in will work but I will stick my neck out and say it will be a backing in not elliptical. 

Artistic Licence.

Ridley has said over and over again the Space Jockey is an Engineer and I do not think he will create continuity over size. Thinking about it I cannot remember a single occasion when he has even considered addressing it as an issue. For people to find that hard is understandable (I couldn't care less, story is what drives me rich powerful ideas and characters) 

The Mission 

Its well remembered that Ridley said in an interview in 2012 that the Jockey was contemporanous within a couple of hundred years  but that thought belongs to the period when they were going to make a broad scope Prometheus follow up and he was done with dragons and all that .... rather than a narrow scope ALIEN: backing into and finding out precisely who the Jockey is.

What we want what we think is elegant and for instance crafts itself around the Dallas dialogue is not going to inform the end game.  

Look how people do not like David created this particular creature as Ridley said a far better idea than the Engineers. So how can the derelict not be connected to David however much we do not like it.

But he could change his mind based on reading Facebook ..again.  

If you get infected twice and you are big enought you can make alien twins?

No more digital xenomorphs, what I love from the Alien movies is that the aliens are real. Digital destroy the magic and looks bad.

'As you all know, the problem with connecting the premise that David created the creature to Alien is the discrepancy concerning time: The Space Jockey, as well as the Derelict, is ancient.'

chli - I think that the problem you mention does not exist:

’Ridley had decided that the derelict ship in the first Alien was one of the group that had gone off and his cargo had gotten out of control, and the space jockey died in the process. So that ship happened to be as it were a brother to the Juggernaut that we see coming out of the ground in Prometheus. They were made roughly the same period give or take a hundred years.

Rick Stammers as special effects supervisor was made aware it might have come from the same factory as the one in Alien, and there again they are not the same ship, it had less emphasis on the bones and organic shapes that were present in Giger's work. Beyond that there is no real link between the two, but it shows who may have had these capabilities to have dreadful weapons beyond anything we could possibly conceive, as sort of bacteriological drums of awful substance that you can drop on a planet.

Because the Juggernaut was carefully stored away underground, Conor O'Sullivan talked about how the details on the walls and the ground are much finer and better defined because the environment is meant to be in almost mint condition.’

Richard  Stammers (Special Effects Supervisor): The Juggernaut might look like it has come from the same factory as the derelict in Alien, but it is not the same ship. The exterior shape is similar, but it has way more detail; and inside, it had a little less emphasis on bones and organic shapes  than were present in Giger’s work. We had two practical set pieces representing the juggernaut, with doorways again resembling an orifice of questionable nature. (Cinefex 130, p59)

Collider interview with Ridley Scott (2012):

Steve 'Frosty' Weintraub :

Can you talk about approaching how you wanted the technology to look in this movie? Because it’s unclear when it is relative to Alien, but this is more advanced technology that they are using than other people have been in Alien.

Ridley Scott: 

Yeah, but I couldn’t help that, because I didn’t know, did I? (Laughs) For all intents and purposes this is very loosely a prequel, very, and then you say “But how did that ship evolve in the first Alien?” Then I would say “Actually he’s one of the group that had gone off and his cargo had gotten out of control,” because he was heading somewhere else and it got out of control and actually he had died in the process and that would be the story there. That ship happened to be a brother to the ship that you see that comes out of the ground at the end. They are roughly of the same period give or take a couple hundred years, right? Other than that, there’s no real link except it explains, I think, who may have had these capabilities, which are dreadful weapons way beyond anything we could possibly conceive, bacteriological drums of shit that you can drop on a planet. -- (http://collider.com, June 1st 2012)

I would be interested in seeing the ultramorph, what they would come up with, as much as i would love to see more of the deacon and even the neomorphs.  One thing that doesn't speak tome personally is the idea of it being very big...it just kind of gives me Godzilla or Jurassic Park images in my head...  I didn't like the height of the Queen and I take its more interesting that a classic Xenomorph is only slightly bigger than a man. It somehow makes it more frightening to me

A huge creature is also more difficult to hide, like in tunnels and such

There is also a huge difference in the way the structure and technology look between the Juggernaut and the derelict ship in Alien. One looks completely biomechanical, the other is just mechanical. Ridley has said these were made a few hundred years apart, but it is a very different looking technology, almost as if these were made by two different races.

@ "Alien life form. Looks like it's been dead a long time. Fossilized. Looks like it's growing out of the chair"

That is what Dallas said it looked like, but Dallas had no way of knowing the age and they did no tests or took sample to determine anything. These were not scientists. Dallas clearly does not even know what a fossil is. Fossils are formed when an organism becomes covered by sediment soon after death. Most or all of the tissue is replaced with minerals when it is ossified, buried in rocky sediments. The space jockey was in the open and still has decaying skin on it. Decayed, but clearly not a fossil.

The larger issue in connecting the movies that I am interested in seeing solved is the huge discrepancy in the size of the Engineer in the pilot chair in Prometheus vs the dead pilot in Alien. In the first reveal shot from Alien with the small scale crew (children in small scale space suits) the space jockey appears to be roughly 3x the size of an Engineer and 4x the size of a man.

Even when comparing a full scale human to the space jockey, just the head alone looks to be 3X the size of the "helmet" we saw in Prometheus. This is clearly a larger creature. Not to mention it looks drastically different to the "suit" we saw in Prometheus. It is almost as if the suit were a facsimile and the one in Alien was the real thing.

Indeed Michelle... RS has hinted that the Bio-Mechanical Athestic is something we have yet to reach... but we will do before the movies link to ALIEN.

So maybe the Synthetic Element has to come to play.

David is shown with TWO Face Huggers, i feel a lot will have to do with how these Procreate or how David can Experiment with them to extract the DNA and apply it to create more Eggs.

Could the Walter/David had escaped with some Black Goo? I think David had enough on his hands within limited time to do this, but then he had enough time to obtain TWO Face Hugger Embryos.

so David has no Black Goo, and no Juggernaught... he maybe does not need the Black Goo, but there has to be at some point a way Thousands of Eggs end up on a Engineer Ship, and so its from where does this Ship come from thats important.

And it being one of the Ships that arrive at Planet 4 before trying to track down David, is a very likely route that the Derelict came from.

Paradise appears to be far away from LV-223/426 and Origae-6 too and so the Derelict ending up in the Zeta 2 System will no doubt be the Event Covered in Alien Awakenings Sequel and Alien Awakening will no doubt set up this 3rd movie that i feel will have to explore LV-223 to give us more Answers from Prometheus and Tie up the Loose Ends.

LV-223 should be no place where Weyland-Yutani can obtain any Technology or Bio-Weapons by the year 2122.

BidDave - 

Yes my initial thoughts were that Walter was left on the Planet for a reason. To either help or hinder depending on his point of view after the David fight.

If David tried to kill Walter as it looked and the two never cooked up a plan, then a scenario i can see is Walter repairing himself and out of duty to the crew tries to find a way off the Planet to somehow help The Covenant.

Were not sure if David spoke any truths, they could be usable ships out there. In fact David might not of been marooned for 10 years. That could be a lie too.

There is nothing in the film or novel that gives fact to any of this. So Walter could find a ship and try to fly but i would prefer The Engineers or The Elders to turn up, see the Tear Drop again and have some communication with The Elders and possibly gain some insight into why they do what they do.

As a creation of The Elders, mankind is to be saved and they set about either meeting up with The Covenant in space OR on the planet David is heading to.

Perhaps we have the Elders wrong and they admire how advanced their creations have become. Maybe it was an invitation in Prometheus and maybe we passed the test.

Just trying to look at some other angles that are sometimes overlooked as they are shot down straight away.

Well this is the BIG ONE and i think the Important One, but this has evolved over the course of the last 5 years, i thought the clues and comments all seemed to point to a Ancient Event and maybe the Hammerpedes... but this Theory is now MUTE!

Things could change however... but it does seem David Created the Xenomorph, from the effects of the Black Goo, but they can change this.

Looking at the Engineers we have to ask WHY, so why do they create Life, what was the purpose, and WHY create the Black Goo and how was this obtained.

For me it keeps coming back to Perfection/Creation, we have to ponder the GOD connections,  and ask WHY did God create Adam when he already had the Angels..?  Other Mythos have reasons for Creation too, some have some purpose of replacement for rebellion which the Annunaki Tale covers, where the Igigi were replaced my Mankind to perform the same task for the GODs after the Igigi had Rebelled.   The Biblical Accounts loosely are the same..  GOD had his Angels, but the Angels proved they could rebel against GOD, so Mankind was created... but then we also had rebelled against GOD.

I think this THEME is important.

But then how now do we get to the Space Jockey, i think we need to look at the reason for Creation, and look at why David wants to create too....   The Engineers are Space Gardeners, they Genetically Modify Creations, including themselves no doubt.

What if a rebellious Faction had then been infected with something that leads to the first Xeno-Strain Organism (Prometheus Fresco) these Engineers who maybe could not Procreate  then saw this Event in some Perverted way that they can Give Birth to Life.

So this Faction of Genetic Gardeners, then decide to experiment with this first Xeno-related Encounter in the Pursuit of Perfecting it.  They maybe then saw the Deacon as Perfect and its DNA being more Favored than their own Engineer DNA and thus they wanted to Upgrade Life on Earth with this more Perfect DNA as opposed to Engineers DNA?

This Playing GOD and incorporating the Xeno-Strain was a Great Hubris that leads to their downfall.

But eventually we will get to the Space Jockey, i think this would then lead likely to ONE of TWO Reasons.

1)The Engineers who return to Planet 4, know about LV-223 and the Xeno-strain and their Downfall.... but they discover and are curious as to how David had Perfected a Creation from their Black Goo.... and they Ultimately in the END decide to take these Creations for Study and Experiments but this again proves to be Costly...

2)Or these Engineers are not aware of LV-223 well as far as the Xeno-strain.... but they find out about the Xeno-strain and what befell LV-223 and these Engineers are then intrigued with Davids Creations and decide to take a look at them for Study and thus leading to their Hubris.

so either of these i think will do, and Ultimately will show the Engineers attempt to take some of Davids Eggs someplace, but then suffer the consequences..  This is how i see it NOW

But they could still change it so that the Event is Ancient

The flight path

Origae 6 to Earth with a diversion to LV 426 where "The priest shall make an atonement for him as concerning his sin, and it shall be forgiven him". Leviticus 4 verse 26

The reason for the flight 

Destroy mankind

Why 

For the reasons David gave to Walter on Paradise.

Why is the creature in A L I E N Bio Mechanoid 

Some synthetic elements are in the creation mix which will be referenced in the follow up, where from ..easy. 

Did the Eggs hug the Jockey or was the Jockey already carrying pre flight. 

The Eggs are cargo protected by the Who's laser. There is no Queen in Ridley's universe so they were on board and haven't suddenly been spawned. They remain on landing on LV 426 inert ready for Ridley Scott to put Kane in front of one.

Then how could the pilot take flight without even considering he was infected. He infected himself unknowingly. He had ingested embryo's when leaving Paradise but because the whole symphony is off he made a mistake over how many he ingested. The sealed container within him broke probably during some robust action in the story and evolved unknown to him. That David is off will I am sure be significant just as the ingestion of the embryos in the movie (which like the revelation to Daniels that Walter is David is not in the book). The number of embryos in the book in the containers are three how many did David de gorge in the movie ?

What happened to the A L I E N created from the pilot

like the Deacon it left the story, having fulfilled its function.

How Did Weyland Yutani in particular the science division know about the xxx121.

The intel from their input to the Origae 6 incident will have been transmitted to Muther at some stage. Its not concidence that David/Walter sends a transmission to Earth that not only regularises the mission and puts it back on track but enable the audience to know they are still in the mix with reasons to retain their interest in the colonisation. 

Where Does the Juggernaut come from ?

Some seriously unhappy Engineers who return to Paradise and will find Walters remains.  

@Chli and Michelle

Liking the Debate ;)  i do think its very interesting what events happened post when Dr Shaw had retrieved Davids Body and Head to when the Covenant arrives.

The Hair Length Michelle, indeed could be a oversight its not like the first time RS has made such a error, or maybe there is a reason for it... but alas only Ridley Scott will truly know, just as with the not so Engineers in Alien Covenant.  I took his comment as Slowly she will put David back together as being a sign that She did not do this right away.  But then who knows how many days or weeks this was.

I think Dr Shaw would be reluctant as the greatest Concern for her is that ONCE David is back together she really is at the WHIM of David, he can do what ever he wants at this point because Dr Shaw would not be needed by him then... unless he has any feelings or pity for her and her cause or if he needs her for his AGENDA... but it does appear a Bond was Formed, we have to wonder how Long did such a Bond Take as it clearly formed prior to arriving at Paradise/Planet 4

From Davids Perspective he does not want to remain in TWO Halves, and so he would have to play a Game of Cat/Mouse with Dr Shaw.... if indeed David could get Dr Shaw to Paradise with just his Head, and talk to the Engineers.... then Dr Shaw would have no reason to put him back together, it would be safer for her with just his Head.  So i think this gives us a reason why the ship was drifting through space for a while, and why she had to set up her own place on that Ship and spend some time there....   David would want to persuade Dr Shaw that without him being put back-together she would not be able to arrive at the destination she wants.

It is going to be interesting to see what Alien Awakening Covers, i am sure while we wont get a The Crossing Movie i would feel and hope that the Next TWO Movies do touch upon some stuff, sadly i am not sure we need to know much about Dr Shaw... but i feel they will have to give more clues to David and those Experiments, and how LV-223 Connected.  So while we may not get to know the relationship between David and Shaw, i feel they will have to cover what the relationship between the Engineers and Paradise and LV-223 was.

@Kethol

Thanks for those images, indeed shows the deleted scenes hold a lot of information, i have studied Prometheus a lot, even some of the deleted scenes but never as far as study in detail the process of the Doors Opening.

As i mentioned in my replies the only way would have been the Engineer shut the door, or it automatically locked, and so thanks for the Screen Grabs as this does look for certain the Engineer had Shut the Door...  Logically in a Hostile Environment the Inner Door would have a Safety where it would not open unless the outer door was sealed.

Kind of Jogged my Memory now as i recall the deleted scene the Engineer slightly squatting for a moment near the panel.. as far as i remember... so this indeed is when he had operated the controls.

As far as the Outside again, the images posted show that there would be no way she would be able to peer through the Outer door from the other side, and if indeed the Airlock Door remained Open which looks likely from evidence you give... or even if not.  She would have to open it regardless to get any kind of look inside.  But more likely it opens up on its own.

As i can only work out what looks like a Panel on the left which i think would be hard to reach looking at how the Door looks if it was closed... This is maybe a Oversight like how you pointed out there was no space for the Doors to Retract too.. but i feel it points to indeed the Doors either Open up Automatically once the Inner door is sealed and outer door opened from inside.  Or it has some kind of Sensor that detects someone outside

The Trilobite moving away again i do recall the Organism had moved away from the Body before the Chest Bursting... and those images posted do show it must have been Alive just prior and during the Deacon Birth Scene.

This does help to raise some Questions as far as how incapacitated it looked to Dr Shaw, if she did come back to take a look. Which is likely.

Indeed HOX i dont think they really look into the Science behind things, even simple things like Location, would have been nice to had been given some information of a departure date and rough location..

So lets take the Pleiades

It would have been nice if they thus had said after the Neutrino Burst that the ship has to be repaired while it was near the 27 Tauri system 431 Light Years away.

And then had mentioned about when they departed, lets say if it was mentioned as December 2101

Then we would be able to work out the ship had traveled at about 140LY Per year, and so then we could work out that Paradise is about  the 410LY-416LY or 446-451LY Ball Park away from Earth.

If this Example was correct then Origae-6 would be about 1400LY away.

@IRaptus LOL i like it ;)  Seems Walter prefers Vocals, but he has passed the being handy with  your hands lesson onto Davids Xenomorphs.....  i can see Walter will have trouble with a Guitar with only One Hand.... but maybe he could Play the Drums like Def Leppard Drummer Rick Allen ;)

@Sherris

Interesting idea and has its Merits, you see we have to wonder how do these Engineers/Elders come into play if they are to interact with David and where he is going.

I dont know how they could turn up and then know were David would be going, as it depends when they turn up, if they turn up soon after.. then maybe they could target the nearest ship but then that dont hold up well for David carrying on his Agenda.

So any Engineers would return once David is long gone, and then how do they know which ship he is on as surely Mankind could have a number of ships out in space.

The Engineers/Elders may figure out where the Ship (Juggernaught) came from either by knowing the results of the Bombardment or at very least tapping into the Juggernauts System and detecting were the Ship came from (if they was not aware about LV-223).

This would surely lead the Engineers to LV-223 or Earth

And as this place is not where David is likely to be heading, then its Logical the Engineers find Walter and from him, they manage to figure out David is going to Origae-6
