WHERE TO GO NEXT?

"...Message to other Engineers in the Galaxy."

I'm just not sure how many Engineers it would take to get justice. Seems like one Engineer was threatening Earth ( Prometheus )?

It'd be cool if the help came from LV-223! And a certain derelict crashed because of it!

The Pickle we are in comes down IMO to Panic..... a Panic to THINK that the Fans want to see the Xenomorph.... and then to come up with a MOVIE that will Begin to take us to ALIEN and then HOW/WHERE do Humans come into Play?

I have said a NUMBER of Times and Made Topics on the Matter... that what they should have DONE was to Make...... TWO Sequels to Prometheus!

1) The First being a Mission to LV-223 maybe a Yutani Mission, but Regardless we have Humans going to LV-223 to Investigate the Disappearance of the Prometheus.  What we have is a more Military Group and then they UNCOVER a Number of Horrors..... we can have it where we see something that is Different to the Xenomorph and Deacon but still Familiar.  You can then have a Number of Clues or some Dialog to make the Connection to the Xenomorph and LV-426.

You then have IN-PART gone and Answered more about the Xenomorph and LV-426 and Provided a more ACTION/HORROR kind of Movie.

YOU can then CLOSE the DOOR to ALIEN.

2) With the Above Movie out of the WAY, then David and Dr Shaw and their Journey does-not have to be Shackled to ALIEN or give any Answers, well it does-not have to be about Xenomorphs.

David and Dr Shaw can ARRIVE at a Engineer World it does-not have to be Paradise, we could have David say he has taken Dr Shaw to a Closer World for her Answers..... or this World could be Paradise?

This World could be THOUSANDS or TENS of THOUSANDS of Light Years Away... WHY it could even be in another GALAXY.....

You could have it that this World we see Engineers (not in Great Number) and Various Humanoid Species which Include Humans who are all Living in Harmony.

This Allows us to see more about the Creation Plot and WHAT kinds of Creation the Engineers would Create (i think its NOT to Create Horrors).  We can maybe GET some of the Answers that Dr Shaw had Wanted....

But Ultimately it would be David who will have the Greatest Effect on the PLOT... how would the Engineers view HIM?  If they seem somewhat to Accept Dr Shaw then would David become Jealous?

If the Engineers are Concerned with David.... maybe they would Consider they have to GET RID of him, and then HOW would David go and React?  He Surely would want to SURVIVE at ANY COST!

The Engineers could become Concerned that Humans had Managed to get to LV-223 and also USE their Technology (via David) and maybe the Engineers would Conclude they would have to DESTROY the Earth.... and then HOW would Dr Shaw react to that?  Would she want to PREVENT this?

If there are Humans and other Species on this World who Follow the Engineers Ways/Religion and Rituals.....  How would those beings view Dr Shaw and her FAITH and would the Engineers become Concerned of that Influence? 

If the Engineers either become Concerned with Dr Shaw and Ponder to KILL her, or to Destroy Mankind and Dr Shaw wants to STOP THEM.... then MAYBE we could see David go on to HELP....   or does he have a Sinister Agenda?

What of the Horror?  What of the Xenomorphs?

Well you could have David go and UNLEASH HELL to Protect Dr Shaw, and then he could have a Sinister Agenda to CREATE his OWN Horror!

I just DONT think the Writers had much of a IDEA or that Ridley Scott, and FOX and Powers that be (Giler and Hill inc) maybe were NOT that Happy with WHAT was being Proposed....

But then Powers that Be.... had decided to make a Movie about the Xenomorph and its Origins and that the Prometheus Sequel would become Part of a Literal Prequel Series that would Arrive at ALIEN down the Line...

And ALAS.... Alien Covenant was BORN...

Well ....what if the Deacon is the creature who chest burst the Space Jockey? That would tie the series together? The Deacon produces egg morphs or something like.

The Space Jockey could have special suit armor ( seemless technology war armor ...something that needs to be extra tough).

"It'd be cool if the help came from LV-223! And a certain derelict crashed because of it!"

I would SAFELY ASSUME that the Engineer we saw in Prometheus was the LAST/ONLY one on LV-223.

We dont know what SHIPS the Engineers would Return with, i am NOT sure that their Main Agenda is to USE HORRORS like on LV-223 like all the Time... it seems that to CREATE and Evolve Civilizations is what they Mainly are Focused on.

But SURELY they would NOT be Happy at Discovering as to WHAT had Happened on Planet 4 and they would SURELY be looking to see HOW they can Prevent this Happening again.....

LV-223 is NOT that FAR away and so maybe they would go THERE and Prepare the SHIPS to Destroy maybe just Mankind on Earth... but maybe they would Target other Worlds they had Seeded to be on the SAFE SIDE?

I think the Engineers would be UPSET and ANGRY.... but i think we have to Wonder as to WHAT they would make of David's Workshop and his Creation (Eggs) and also WHAT would they make of Walter?

Have they seen a None-Organic Synthetic Before? Well Certainly a Robot of Sorts?

As far as DAVID goes..... i would either IGNORE to where he Goes/What he does! (leave that a Mystery or for Future).  We do-not NEED to have David to get Eggs... there are like 6-8 Left (maybe more) on Planet 4

Or as Discussed we have the Covenant Land on LV-223 and the Engineers and other Humans will TURN UP at a Later Date after David has been on LV-223 for 1-2 Years.......

"what if the Deacon is the creature who chest burst the Space Jockey"

I think with Alien Covenant and showing that David is the ONE who Begins to Create the Xenomorph i think its UNLIKELY that the Space Jockey would be Infected by a Deacon that then Produces the Eggs.

But YES the Space Jockey is Chest Busted by something.... and we have to ASSUME its in the Cargo Hold/Egg Chamber.... some have in the Past gone to Speculate the Space Jockey gets Infected on LV-223 and then WHAT EVER has Chest Busted has MADE its WAY into the Cargo Hold to then Lay/Create the Eggs.

The Egg Morph is Interesting as i THINK that we could USE this to get to the Thousands of Eggs, if we have it that either.

1) David is able to Infect the Colonist (even their Bodies Dead/Alive) and they become/Morph into Eggs.

2) As above but its the Engineers who do this....

3) David or the Engineers will Create a Organism that can Egg Morph the Colonist.

These would be a way to EXPLAIN THE EGGS...

There is ONE MISSING PIECE of the JIGSAW!

The Xenomorph from Alien Covenant is NOT YET the Bio-Mechanical Fiend that we see in ALIEN, and RS has said it has NOT YET achieved that YET and it will have to EVOLVE before we get to ALIEN.....

The more Mechanical/Synthetic Element will have to come into PLAY... and maybe a Synthetic will PLAY that ROLE.... the Xenomorph in Alien could be a Alien Covenant Protomorph/Synthetic Hybrid.

Okay..then... the Deacon is a queen hybrid and when it reaches maturity begins laying eggs aboard the LV-223 juggernauts and these eggs produce deacons NOT xenomorphs ( that's David's bag ). ? It only makes sense that the Deacon is special...coming from a crazy mix of a male human, an INFERTILE female Trilobite Engineer mash up!

Or the Deacon uses the bodies ( Vickers, Janek, etc..) found in the wreckage to egg morph the cargo. ( still not xenomorphs but Deacons )

Like you said, Space Jockey died from something other than a Xeno burst., so the Deacon makes a good choice.

A female Engineer could have been the pilot and the Deacons eggs do interact with the hosts sex and female burst produce queens? ?

Either way the derelict origins are messed up. David HAD to plant the eggs to produce a xeno type aboard the Nostromo.

Though we should clarify that David type xenos start life as miniature versions and Deacon types as hammerpeade  snakes.

The Nostromo Kane burster was clearly snake like and not Planet 4 type ( fully formed but a small )

"Like you said, Space Jockey died from something other than a Xeno burst., so the Deacon makes a good choice"

The Space Jockeys Fate has always been a Mystery but Ridley Scott had Explained it, he had Basically Confirmed that after the OUTBREAK on LV-223 some 2000 Years ago; that something had EVOLVED in the Cargo Hold and Infected the Pilot.  Therefore he had Envisioned at the Time of Prometheus that something had Evolved in the Cargo Hold over a Few Hundred Years which became those EGGS.

HOWEVER..... all BETS are OFF at the Moment as it is OPEN to Different Answers but ONE THING seems Certain.... the is NO Derelict on LV-426 as of the END of Alien Covenant and the Space Jockey will become INFECTED by a XENOMORPH but by a Xenomorph thats a EVOLUTION of what we saw in Alien Covenant.

Regarding the Deacon..... well the ONE that we saw at the END of Prometheus we have to Remember a Few things..

1) It is a Infant and so it will LIKELY go on to Grow 3-4X its Size and it may LOOK more Menacing as it Gets to Adult Stage.

2) It is a Hybrid and the Trilobite was some kind of Hybrid Face Hugger that had a LOT of Human/Mammal DNA.   And so THIS may be Passed onto the Deacon and so maybe the Deacon would Procreate like a Mammal?

So the Deacon i think would maybe NOT go and Produce Eggs, maybe it can Procreate without Sex, maybe it does-not Require a Host?   And so maybe it can Give Birth to Live Young every Few Hours or Days and these would GROWN to become more Deacons?

But YES we could also Explore other WAYS it could Procreate....  The Egg Morph or Similar, or maybe it Infects a Host that would Mutate into a Deacon/Human Hybrid?

What BECAME of the Deacon would Depend on the Following...

a) How Long does the Deacon Live for?

b) How does a Deacon Procreate? Can it Procreate?

c) Does this Require anything like a Host? or Genetic Material?

d) Can the Deacon become Infected with the Black Goo?

e) Can the Hammerpedes Infect a Deacon?

The Hammerpedes are another Topic for Discussion as its LIKELY that there are More on LV-223 and so the Questions i ASK about the Deacon can APPLY to the Hammerpedes too.

LV-223 as of the Year 2094 had a Deacon wandering around and at LEAST 1-2 Hammerpedes.

The Female Engineer is Interesting as we have to ASK the same of a Female Human, does a Infected via Black Goo or Face Hugger etc have the same Result if its MALE/FEMALE or can they Produce something Different?

"...NO Derelict on LV-426 as of the END of Alien Covenant.."

Just another reason not to write a Origae-6 movie. There would have to be more plot conveniences to shake a stick at if David finds another Engineer outpost on or around the Origae system, then finding another juggernaut( they are the used cars of the galaxy ) to load up with his eggs. Yeesh.

I could deal with Planet 4 having many juggernauts or maybe a manufacturing factory where you can grow your own. One that could fit a 13 foot mutated monster /David in a seamless chair.

"What BECAME of the Deacon "

A good reason to have a LV-223 movie where a rescue ship is sent to find out what happened to the Prometheus. Half the rescue ships crew gets eaten by the Deacon and David arrives in time to kill the rest. 

I barely see the A.I. / W Y disregarding the Nostromo disappearance......But really don't see Peter Weyland and his daughter brushed aside.

Indeed it would just be another Coincidence if Origae-6 was a Engineer Outpost, so what we have been Theatrically to LV-426 (Twice) and there is a Engineer Ship, we been to LV-223 where we have Engineer Ships, and then Planet 4 with Engineer Ships.... to go and have Oriage-6 as another Place with Engineer Ships would just be TOO MUCH of a Coincidence...

As of Alien Covenant we are 88 Months from before David will Arrive at Origae-6 if this is where he GOES..... so he would Arrive about the First Week of April 2112 some 10 Years and Two Months or so before the Nostromo Arrive on LV-426.  There is Quite a BIT to Cover in those 10 Years before we get to WHEN the Nostromo will Arrive.

It would be LIKELY that the $&£% Hits the Fan (Engineers Arrive) between say 2114-2116 and so then we are LEFT with the Derelict being on LV-426 for what?  5-7 Years say?

So IF they made a Sequel/Continuation then i think they either have to

a) Take the Covenant Ship to LV-223 (take 4-8 Weeks Tops)

b) Simply do-not have WHAT it is that David does NEXT have any Effect on LV-426 and so the Events that Lead to LV-426 will come from Planet 4 (Eggs) to LV-223 (Mass Produce/Evolve).

"I barely see the A.I. / W Y disregarding the Nostromo disappearance......But really don't see Peter Weyland and his daughter brushed aside"

Certainly..... its Interesting as to WHAT becomes of Weyland Industries in the Years Following the Prometheus Mission, we know the Company will Merge with Yutani at some Point over the Next 3-8 Years and with Yutani being BIG on Software and Communications, in the Background Information its Indicated that the Prometheus has some Yutani Tech!

And so you would ASSUME that either Weyland or Yutani or the Merged Company would have GONE to LV-223 before the Covenant Mission and in doing so as Planet 4 must be Located within say 10LY of LV-223 then we had to ASK as to HOW they Never Detected Planet 4?

It all came down to the PLOT CHANGE.... and Plot Conveniences Needed...

IF the Sequel to Prometheus was to Literally Connect to ALIEN via 2-3 Movies and with a 28 Year Period to WHEN the Nostromo would Arrive on LV-426, then for the SET UP you would NEED to have Human Characters and so by Virtue of having David go to a Engineer World.... then this WORLD could NOT be Placed like TOO FAR away so that Humans in the Years 2100-2105 could Reach within a Short Time.

For Example if David went to a World say 1600LY Away then the Nostromo would have taken 33+ Years to get there and so WHAT are the Chances that W-Y Ships that are 10+ Years Older would Arrive like PRIOR to ALIEN... Thus Planet 4 had to be Located more Closer.

So for ME.... the BIG MISTAKE they had Made.... was to have a Literal Prequel and bring back the Xenomorph.

Ridley Scott wanted to GO where David and Dr Shaw would go and to STEER AWAY from ALIEN and Xenomorphs.... but then the Powers that BE had Decided to make a Literal Prequel Route.... and introduce the Xenomorph and its Origins and as RS wanted to KEEP it so David was a Important Character.... then Sacrifices had to be made....

NOPE!

They should have Sacrificed Davids Journey (well put this on HOLD)....

And they should have GONE BACK to LV-223.

What about David????  well they Send Down another David Model but ONE who is more like a Walter....  This David could Establish some Connection with the Systems in the Life-Boat to get some Information... maybe he would Detect some of the Interests and Stuff that David had been up to?

IF they then go to the Outpost that Weyland had Met his Demise, then WHAT would the other David be like when he sees his Creator is their DEAD!

Prometheus had CLUES to ALIEN its just they was NOT like SPOON FED... its Pretty Obvious that the Xenomorph was Connected to LV-223 in someway, and that a Engineer Ship at some Point must have LEFT this Place with those Eggs or maybe it was Arriving with those Eggs?

There were at LEAST 4 of those Complexes on LV-223.

Do we ASSUME that Each of the Complexes had Exactly the Same kind of Experiments?  Did all of those Complexes have the Exact same Black Goo and Effects?

Ridley Scott had Indicated that the Derelict was on LV-223 at some Point and that the Derelict had Ended Up on LV-426  within a Few Hundred Years of the Outbreak and that SOMETHING had Evolved in the Cargo Hold.

And so then you can ASK.... was the Derelict the ONLY other Ship that had something Happen/Evolve in the Cargo Hold?  If something had Evolved from the Experiments/Black Goo to give RISE to those Eggs, then there could be Similar on LV-223.

You could have something SIMILAR but Different to the Xenomorph where you would see a Connection but you would STILL NOT have it Spoon Fed but where the Conclusion is Easy to see.

So SAY they Encounter something like above in another Complex on LV-223 or in the Cargo Hold or even a Underground Egg Silo etc...... and IF there are Enough Clues to HOW the Engineers had Obtained/Created these NEW Xenomorphs... then you can LOGICALLY had Concluded that the Xenomorph in ALIEN had a Similar Origins.

The FANS get some Answers, they get a more ALIENY MOVIE.... then the DOOR to ALIEN can be Closed!  But you OPEN the Franchise to more Xenomorph Variants.

THEN............... Ridley Scott would be FREE to go where David and Dr Shaw are Heading and NOT have to be Shackled Down to ALIEN or the Xenomorph and to then OPEN UP a Expanded Universe Spin Off.

But ALAS....

"...LEAST 4 of those Complexes on LV-223..."

Yeah, not knowing how much black goo it takes to cleanse or reset a planet is problematic. Also how many worlds are they targeting? Hundreds? Thousands...Millions? Probably need a lot of canisters. David wiped out a city with a filled juggernaut...but that was just a tiny area of the planet.

"..RS wanted to KEEP it so David was a Important Character..."

Great point!    Could of Had David explore the derelict on LV-426, cutting the hole in the floor...removing some eggs and setting the distress beacon would have been enough for me.

"...For Example if David went to a World say 1600LY Away then the Nostromo would have taken 33+ Years to get there and so WHAT are the Chances that W-Y Ships that are 10+ Years Older would Arrive like PRIOR to ALIEN... Thus Planet 4 had to be Located more Closer.."

I think you are giving the writers too much credit! lol! 

Peter Weylands body aboard the juggernaut: Probably crushed or pulped from the collision and surface tumble! Maybe the Deacon fed off it for awhile and there is nothing left ( egg morphed? Peter is in the cycle of life ) OR some black goo canisters opened during the tumble and some goo covered his body and reanimated it...Zombie Peter Weyland would be cool! 

"Probably need a lot of canisters"

Ridley Scott had Claimed that it would NOT take a Lot....  The Juggernaught Model Ships seem to have 6 Cargo Holds and Ridley Scott had said that ONCE the Bio-Weapon gets into a Water Supply it can EFFECT a LARGE AREA.

With Alien Covenant then it seems David had Unleashed just a SINGLE CARGO HOLD, the Bio-Weapon seemed to NOT have a Large Radius as a Pathogen it would NOT have taken a LOT.... the Very First COVID19 Outbreak had came from a Small Source.... but the Black Goo seemed to be Different to a Pathogen/Virus like COVID.

With Prometheus and Comments by RS it seemed to Indicate the Pathogen can EFFECT a Large Area, but with Planet 4 then it Seemed to have a Different Effect than Expected.

We saw the Urns Explode and the Liquid from Prometheus had seemed to Become more a Mass of Particles it was more like Raining Down Black Grains of Sand than a Black Thick Liquid.  The Pathogen also seemed to look like it HIT a Invisible Dome before it Penetrated.

Could there had been a Force Field that Protects the City (well Courtyard) but it was NOT made to withstand a Black Goo Bombardment or it Failed?

The Pathogen seemed to Become a Thick Liquid of Sorts when it Infected the Engineers and it seemed to Replicate/Grow in Amount and then seemed to Explode/Escape from the Engineers and then Spread to Infect others.

But all the Bodies by the Time the Covenant Arrive seemed to be Turned to like Stone.... well they Dried Out like some Amphibians can.

This is NOT what you Expect from Prometheus........but IF you knew of a Pathogen that is Organic and Infects Organic Matter and can Spread via Organic Matter, then HOW could you STOP IT?   If there was something you could CAUSE that would DESTROY all Organic Matter..... make all Cells/Molecules become DEAD then they could Prevent the Spread and also HALT the Pathogen.

If you had something that would RENDER say Genetic Material in way to Crystallize it, or Dehydration Organic Matter... then maybe the Pathogen can NO LONGER be Effective?

Take the Gekko on the Right.... if this was Infected with some Virus etc but there was something that Could Instantly Dry it out like the Left then Chances are the Virus would also be Halted.

If the Engineers had a SAFETY DEVICE like this... and they Activated it then this could EXPLAIN why the Engineers looked like Dried Out Mummies... and then WHY it was that David was able to Find Life on the Planet and some Alive Engineers.

Such a Safety Device could have a RADIUS and so Everything within so MANY MILES could be Effected.... Apart from Engineers who are away from the Radius or they are WITHIN a PLACE that is Shielded from it....

Thats NOT to say this is Correct.... it could be that those Urns in that Cargo Hold were Activated in a Certain Way or Programed a Certain Way to do what we saw in Alien Covenant.

The Neomorph Spores seem to come about from Knocked Over/Leaking Urns in another Cargo Hold after the Juggernaught had Crashed and its Contents then Infected/Mutated some Fungi Spores that had Developed.  The Neomorph Spores are something you would Expect from seeing Prometheus and HOW the Leaking Urns had Affective Organic Life.

"I think you are giving the writers too much credit! lol!"

Indeed this has Happened in all the Sequels to ALIEN.... when they Need a Plot they come up with something for Plot Convenience without giving it MUCH of a Thought because we are MAYBE just NOT supposed to ANALYZE the Movies too much ;)

"Zombie Peter Weyland would be cool!"

Ha Ha..... Yeah who knows what the Black Goo can do... when somebody Dies it takes TIME for all their Cells to Die and Decay......  If you say had COVID and someone had Died and you Tried to give them the KISS OF LIFE then while they could NOT be Saved.... you could still had Passed the Virus to them and the Virus would be able to Reproduce/Spread with the Fresh Host... even after Death... Unless they had been Dead for Long Enough that their Cells begin to Die/Degrade etc...

So YEAH maybe the Goo could bring Weyland back to LIFE.... and HOW like IRONIC would that be.... he wanted Immortality or Extra Life and he is Resurrected as a Zombiefied Horror.

Regarding David as a Important Character then YES that what RS thought...

With the PLOT IDEA i Proposed as a Prometheus Sequel... then having a Mission go to LV-223 and to NOT go and follow David and Dr Shaw... does-not mean we CANT have Fassbender.... he could have came to LV-223 as another David Model... like Walter was...

If we go for a Alien Covenant 2 where we again DONT go where David is going, the Company could SEND in another Walter/David Model and we also have Walter on Planet 4.... what STATE is he in?

For me i think that going to Planet 4 again is the WAY to go NEXT!

The Company will KNOW a bit of WHAT it is that David has done.. the Advent Message seems to Indicate that Planet 4 is where the Company would FIND the WOLF that David has Created... it seems LIKELY they would go to Investigate.

We see that David is OFF to what we can ASSUME is Origae-6 and he has just the TWO Tiny Face Huggers....

Planet 4 has that Room that David had showed Oram the Eggs... there is like SIX of those at Least that Remain.... and THEN we have to ASK to WHERE was it that David had GOT the Tiny Face Huggers?   In his Workshop we see Tiny Eggs, and so HOW MANY MORE of those Tiny Eggs are there?

And so Planet 4 has MORE like Xenomorphs than David is Carrying with him on the Covenant.

To CONNECT to ALIEN..... we have to see Davids Xenomorph be Evolved a BIT and then END UP on the Derelict on LV-426 in their Thousands..... 

Well you DONT have to Follow David/Covenant to Conclude such a PLOT...

The Company/Engineers have MORE than Enough Eggs on Planet 4 to then take to LV-223 to Mass Produce and LOAD onto Ships... and we then KNOW what HAPPENS after this ;)

A Alternative that has been Discussed before was that WOULD we see David wait to get to Origae-6 before he Attempts to Experiment on the Colonist?  Or would he do it DURING the Journey?

WHAT HAPPENS when things GET OUT of Control?

WHAT HAPPENS when another Ship then Intercepts or Investigates the USCSS Covenant should it become a SPACE HULK?

Thanks for sharing such a helpful instruction, really appreciate for your article.

MCDVOICE

"...Company/Engineers have MORE than Enough Eggs on Planet 4 "

Yes...I agree, Planet 4 is established. Don't have to break the budget creating a new world (Origae-6 ).

Walter is a Bishop like character and we need closure.

The Engineers catching David and returning him to Planet 4 makes sense. Maybe to stand trial? RS would probably like that. Also Shaw's grave is there and maybe a chance to do something with that angle. Plus plenty of spores.

"....WHAT HAPPENS when another Ship then Intercepts or Investigates the USCSS Covenant should it become a SPACE HULK..."

Yeah, that would make a good movie and easy on the budget. David and his creations versus marines. I'd pay to see it! 

Reanimated Peter Weyland would be a nice 3 or 4 page Dark Horse comic Halloween issue.....But I don't see Marvel doing anything cool like this.

Though with Marvel's "WHAT If..." series?? Alien would be a great for this.

"Yes...I agree, Planet 4 is established. Don't have to break the budget creating a new world (Origae-6 )"

I dont think that Origae-6 would COST a LOT to Create.... i would Imagine the World would be like the Location that Raised by Wolves or the First Planet of the Apes Movie were SHOT... and so it would be kind of Baron, more Desert like but it would have Water and Vegetation just it would NOT be a Lush Wooded Environment like Planet 4.  I assume this as Daniels wants to Build a Cabin on the Lake, so it has Water, but then they Determined that Planet 4 is more Suitable Beyond the Best Estimates for Origae-6.  I think the Planet would have NO Intelligent Species and it may have NOT as much Life as you would Expect to Find in a more Green/Cooler Climate.

The Problem with going to Origae-6 if the Events of this would IMPACT the Path to ALIEN is you ADD another 7+ Years to that Already TIGHT Deadline of up to 17 Years before the Nostromo turns up at LV-426 and thats WHY i WOULD give Origae-6 a PASS.

"The Engineers catching David and returning him to Planet 4 makes sense"

Who knows what the Engineers would DO if they Catch Him... i am sure IF they Discover he had Caused what Happened on Planet 4 and they would due to the Holographic Recording Tech.... then i SUSPECT they would just TEAR HIS HEAD OFF and SMASH IT UP!

As FAR as WHAT they would do with the Colonist.... well they COULD THINK........ like "Ok so you guys have Caused all this to OUR WORLD, we are Gonna take them Eggs and those Humans and Experiment with them or USE them to Create other Horrors"

I Suspect the Engineers see us as Insignificant...

They may be Intrigued by David/Walter though but IF they Discover that they (Synthetic Humans) are the Reasons for those Dead Engineers, then i think they would want to DESTROY them ASP!

How would they REACT if they came Across say Modified/Genetically Engineered Human Hybrids?   So they would see a Humanoid Form that THEY had NO PART in the Creation/Evolution of.... maybe they would be Intrigued/Interested?

I think having something SET on the Covenant could Work.... i Proposed a Idea some Years Ago....

David does begin to Experiment on some of the Colonist..... but his Experiments will GET OUT OF HAND......

We Begin the Plot/Story with the Covenant Floating in Space and it Arrives near Origae-6 (or maybe NOT) but something Happens to Awaken some of the Colonist, they go to Explore the SHIP and they Discover Horrors.... Parts of the Ship have been Quarantined Off... the Awoken Colonist then Discover as to WHY..... as they FIGHT to Survive the Menace of Xenomorphs..  They Discover in Cryo-Pods some Modified Human Hybrids.... who Pose a Threat too when ONE is Released from its SLUMBER...

Some of the Colonist then Discover... Walter he is Torn in Half.... he asks to be Repaired and Gives some Excuse to WHAT had Happened... as he is Repaired/Uploaded to another Body.....

They come Across Daniels... she is Incapacitated she is Mutated into a Hybrid and she then ASKS to be Killed..... but either Warns them.. or they Discover that Walter is NOT who he Claims... 

Its then just to Figure out the Ending..... does the Ship go and Crash on Origae-6? or another World?  The Surviving Colonist will Escape in the other Lander/Loader.............. or David Escapes in that... and the Colonist attempt to Crash Land the Covenant?

The Problem we have is HOW do you have the Engineers Involved.... that would be TOO MUCH to FIT into One Movie... UNLESS you RUSH or Sacrificed Parts.

One Solution is the Covenant goes to Near LV-223 but then SURELY as its Close then David would take Colonist etc down to LV-223?  so there would be LITTLE POINT in the PLOT i have Given!

The other OPTION would be that the Engineers will Turn Up at the END with Walter as some HOW he has been able to Inform the Engineers or where David/Covenant was going.... or that the Engineers gained this Information from Walter in some way.

The Problem is we are going to Origae-6 and so the END of this Movie would leave about 10 Years before the Nostromo will Arrive at LV-426.

For me you just LEAVE it so David/Covenant will go to Origae-6, well we SIMPLY do-not go and FOLLOW them....

Company Arrives at Planet 4... maybe with another Walter Unit.... they Discover Horrors, Davids Experiments etc ect.... and then Walter and Repair Him....

Some Scientist on the Mission have a Objective to OBTAIN a Specimen... and WALTER will Refuse to Allow that.... but he then gets into Conflict with the OTHER MODEL that is with the W-Y Science/Rescue Vessel..... who like ASH will Comply with Gaining the Specimen.

The Engineers can Return at the End of the 3rd Act to then SET-UP a Sequel... this Sequel will Conclude with going to LV-223 where the Engineers or Company/Synthetics will MASS PRODUCE the Eggs we see them Loaded to a SHIP and you can LEAVE IT at just that.....

The Events of these TWO Movies will be Closer to LV-426 and could TAKE PLACE like 3-5 Years after Alien Covenant...

If they involve the Engineers again.....I think their story needs to end ( killed / transcend / etc..).

Or..... Maybe this isn't the Engineers galaxy. They just arrived ( millions of years ago ... quick on the galactic timescale! ) and have yet to populate the galaxy ( just Earth and a few dozen planets).

Setting the Engineers up as the creators (seeding the galaxy! There're everywhere!) then dumping them after a few scenes is just bad. 

If RS sees a cool location then we'll likely see an Origae-6 movie.

Wherever they go...I'm 100% sure the next movie will have to include xeno's and marines.

Well the SCOPE of the Engineers is MASSIVE.... but so is the Size of the Galaxy, the Engineers could be Located in other Places like 5000, 10'000 even 25'000 LY from Planet 4 and so they maybe would NOT see our Expansion as a Massive Threat, but they would be IF we could USE their Technology and Reverse Engineer it.

The Engineers could be Mainly Located in other Galaxies too....... the Engineers could RETURN to Planet 4 like every 200-500 Years.  Have they ever been back to Earth to check on us like 500, 1000 Years ago... and IF they did they would NOT see much to Worry about...

Our Technological Boom began 200 Years ago, and we have made Incremental Advancements since then... and Especially the Last 50 Years.

On a Galactic Scale... the Engineers could be Few and Far Between and our Galaxy is HUGE.....

I would have taken the Prometheus like 1300 Years to Reach the Center of our Galaxy and for the Covenant about 600-650 Years.  However as we Progress in the Franchise Time-Line the Ships get Faster.

Regarding to Actually see a SEQUEL.... i am NOT sure we would EVER see any or any Conclusion to the Prequels.  I think the NEXT ALIEN MOVIE we would ever see would be more like a ALIENS.... and i would NOT RULE OUT the Future of the Franchise being Rebooted as FAR as the Prequels... i FEAR that the Prequels will NOT be Classed as Canon in 10 Years Time.
