Katherine Waterston delivers worrying Alien Covenant sequel update!

Kathy I won't shed a tear.

This is a scenario where they do honestly need to go the reboot route. 

I am not very saddened by this, it would be nice to get another prequel movie but if that would mean another David movie then forget it. One side of me says that it is bad news but another side of me says that they (Fox and Scott) sort of deserve it since they messed it up by going the android route at the expense of human characters.

I agree with all of you. (David should die in the next movie).

Whatever the case, a full remake would be a mistake.

Will not go and see whatever they do if its about David vs. humanity.  Bring in some fresh minds and come up with a better story like the Engineers are waiting for Covenant on Origae-6.

There is potential, they just need the Right Story.... I am FREE if Ridley Scott wants someone to Share a Few Martinis and Brain-Storm some Ideas ;)

I dont think Reboots, or Ret-cons are needed.... i also DONT think we need a Blomkamp Alien 5.... but i would certainly think his ideas could be used in a connected movie... just Re-work his ideas to NOT contradict the Prequels and Franchise and NOT introduce Ripley, Newt and Hicks.

They could choose a Time-Line between Aliens and Alien Resurrection where Blomkamps ideas could be used that DO-NOT have Ripley but introduce other Characters....  or even use his ideas set Prior to ALIENS where Miss Weaver can come back with a bit of make up to make her appear a bit younger and different and PLAY a Older Amanda Ripley..

Where we get the reveal she Does-Not Die how Ripley was told, but she Sacrifices herself to Prevent the Company getting the Xenomorph and Engineer Technology leaving only LV-426 as once again the only place for them to acquire the Xenomorph.

EVEN... doing a Alien Resurrection Sequel and using Blomkamps ideas in that..... BUT NO  Alternative Alien 3 route please.

Oh Regarding REBOOTS.... i think one likely Reboot could be the AVP Series which if done right and set within the Time-Line of the Alien Franchise so say 2150-2250 could be a Popcorn Flick that Disney would like for its Merchandise and Toy Potential

I am not up on time lines BigDave, but I like AVP and it could be a good direction for Disney to go. Sure, it would disappoint a lot of fans for many reasons, but it could also draw newer fans. I would not be against that direction since the current situation seems to have painted itself into a corner in some ways.

please please please roll her up in a body bag

ali81

"Well it ain't no easy grab! They got T!"... Maybe they'll have a cowboy hat burst.

What i meant DK was that the AVP Franchise had that Popcorn Franchise Potential.... but instead of going the Route that the Comics and Mainly the Games had taken....  The AVP Movies where brought in to be close to our Present time..  instead of being set Hundreds of years in the Future... with a Space Fairing Humanoid Race and the Colonial Marines etc.

I actually think a AVP Reboot set in the Time Period of say Alien and Alien Resurrection as a Alternative Universe and so NOT Canon to the Alien Movies would potentially be the least risky route for Disney to take.

Another Less Risky Route would be to explore some Alien Movie set between Alien Isolation and Aliens.

I think the Prequels have hit a Snag now.... its how do they Finish it and give us something they could make their money back on... Some still Want Answers Spoon Fed, others Do-Not want to be left with the Lingering Truth that David Created the Xenomorph.

A Literally Alien Franchise (Ripley) Sequel would be tricky for a number of reasons, be it continue a Alien 5 (sequel to Alien R) never mind Ret-con Alien 3 and Alien R

I think a AVP Reboot is more likely at the Moment.

@ ali81

you don't want her in a body bag, you want her to be chest bursted. ;)

"I had heard some rumors about where it might go a long time ago that were really interesting to me and my character"

This is one of the things we had to ponder as what was next for Daniels, the way AC ended with that Reveal does-not bold well for her.

*David could not risk her being alive in case she Tells/Warns everyone what David has done and intends to do... for him he Logically has to get rid of her... Unless he intends to only wake a Colonist a Time and Experiment on them ONE-BY-ONE but this would be so much of a David movie and no Characters... unless a incident happens where a Number of Colonist are awoken in ONE Go... then David would have to do a lot of covering up and if Daniels is Alive and gets to the other Colonist thats not gonna make Davids job easy.

*If David Kills her, but then awakens Tennessee pretending to be Walter then surely Tennessee would wonder what happened to Daniels and what is David going to say?  So Tennessee would likely get suspicious and then he would suss David out or David would have to get rid of Tennessee.

The Advent Viral Suggests David now has to Perfect his Queen, and so we know David is a bit Crazy and Megalomaniac and no doubt arrogant that maybe he would love to keep Daniels Alive but incapacitated a bit so she can Witness EVERYTHING David is doing and is planning, this would FIT with how Twisted David has become. 

But then for something to happen, where Daniels Escapes him and then manages to Activate/Open most of the Cryo-Pods the Colonists are in would pose a Great Problem for David.

I think something like this has to be the Logical Way a Miss Waterston could play any real role in the Next Movie....   Why David could even Set-up his Colony on Origae-6 and things go happy and well for him, the Colonist Fed some BS by him....

But a Hubris for him is keeping Daniels Alive hidden someplace... that when she is Discovered.... it would OPEN the Colonists Eyes to what David has been doing and WHO he is.

My Alien: Ascension idea covers very similar to this... i was then pondering if Daniels Escapes...?  Or if she only is able to Warn some others after Davids Secret Underground/Underworld is Discovered.

A lot depended on HOW Daniels was being held by David, was she merely being kept in a Cryo-Pod with Tubes attached etc to extract her Eggs.... or was she more Hard-Wired into something that removing her and saving her would not be a option? 

movie fan

yea now that iv thought about it I want that. mouth raped by a hugger then the agonising death of a baby xeno chewing its way through her chest cavity. id pay to see that,n, maybe watch the rest of the movie

According to me,  the new storyline which began from Prometheus is awesome. I am starting thinking that they want to lock this trilogy as Prometheus is not so fantasy after all...

@ali

I think the Chest Bursting Route would not be so Original... and it shows really the Wasted Potential with Dr Shaw...

You see if Daniels will be Davids Queen then how does this work?

1) Royal/Modified Face Hugger ==> Daniels ===> Xenomorph Queen?

2) Egg Morph Daniels ==> Royal Face Hugger ===> Host ==>Queen?

3) Same as above but Tennessee = Egg Morph  and Daniels = Host?

I think these three ideas would be a bit limited.... so we could have the route seen in AC.

4) Daniels Eggs are used to Produce Davids Cache of Xenomorphs Eggs?

Or as some of the Concepts for AC showed and Davids comments...

5) Evolve Daniels into something else that produces the Eggs?

OPTION 4-5 are more disturbing and i think Especially Option 5 would have fitted more if we actually had seen Dr Shaw in the Sequel to Prometheus.

David offering Dr Shaw a Gift, Evolving her so she is No-Longer Baron and Can-Now Create Life.... only its not Life as Dr Shaw would ever had imagined... a Perverse way for David to grant Dr Shaw a Gift of Creating Life.

Maybe something like this would be interesting to explore with Daniels?

Bigdave, I agree, option 5 would be the superior choice for sure. I honestly don't think we are getting a sequel. I think they are going to do a soft reboot, Alien 5 or AVP reboot...

@ali81 @BigDave

Even if she dies, we won't see it on screen, as we did not see in neither Alien, Prometheus and Covy to honor Dan O'Bannon. Sir Scott might change that but that would be already AVPR territory and he wouldn't lower himself there. In the movies how many women are chest bursted? 1 in Aliens and 2 in Resurrection and Ripley in cubed?

And why everybody thinks that David will create a xenomorph queen? What I can tell for sure that the queen in this context is Bathsheba and as in the Bible story, David's "affair" with her will mark the start of his Downfall, meaning he will lose the control of the aliens. But this queen is probably a curve-ball (unless it will appear only to pander to hardcore fans).  

Shaw could have not be baron, eventually baroness, but how many nobles die in missionary work? :P  And was her biggest desire to have children, even if she was barren and especially after the trilobite incident?  Wasn't her quest moral in nature ? To dream about having children and or having a cabin by the lake are making me puke especially in a Sci-fi setting, when you could explore the whole universe.  

"like the Engineers are waiting for Covenant on Origae-6."

I think it would be a bit too much of a Coincidence if Origae-6 is a Engineer World, and how would that Bold for David arriving to discover the World is Inhabited by Engineers...    We get into the Problem then of David introducing himself, and how does the Humans come into play...

Not that this can be ruled out though...

I think maybe at best we could see Origae-6 has signs it used to be inhabited but i think discovering the World has Engineers or other Humanoids MAY be to much of a Coincidence.

Ridley Scott has given us some clues...  as he ponders.

*What kind of a World would David Create?

*Hints they are off to the Planet (i assume Origae-6)

*Movie will be less Xenomorph and Focus on AI

*RS mentions Baty and Racheal (Replicants) are a kind of AI so this reveal could mean the LV-223 Engineers are AI

*RS reveals that they will arrive at Origae-6 (likely) but that 3-4 incoming Parties will be arriving...

*RS reveals that ONE of these are the Engineers who return to Planet 4 and discover the destruction and are not pleased and so they will be off to find the Culprit (David).

So there is Scope with the Next movie, but it has to be handled very well and already a  lot of Fans are not pleased on the David Story and the Plot being about him and his Creations... and a lot of Fans are displeased at the Action and use of the Xenomorph.

But RS has a War of the Worlds kind of Plan how to expand the Franchise and i think this is more than Humans vs Engineers vs Synthetics vs Xenomorphs.

ignorantguy I like your idea of the downfall and losing control of the aliens. There are so many promising ideas, but I don't we will see another movie but who knows with RS's pull. 

@ignorantGuy

Good points...  and while Disney may not want to make a Cert 18/Hard R Movie.... i also think they would not want to explore Chest Busted Females, i think even the AVPR Pred-Alien Impregnation Scene is something a Disney would never Touch...

I feel David's Queen would not be the traditional route, which means a Chest Busting for Daniels and a Queen like we had with Ripley in Alien 3.

As far as Dr Shaw.... i feel it shows she may have wanted Children but she realized she cant, this seemed to be something that bothered her when she answered Holloway about she cant create life...   And also the Shock when David told her she was Pregnant.

I would think there was the Potential that if Dr Shaw was offered by David or Engineers a Chance to be able to Give Birth and so FIX what ever is preventing her from being able to have a Traditional Baby. I think she would have taken such a chance.... especially if she found out she could gain NO Answers from the Engineers.

So there was a lot of potential that a Sequel could have explored...

I wonder if a lot of this Potential would be explored in the Next movie or would have been.... as it seems bizarre how the Movie ended which does not bold well for Daniels.

A few things i picked up more, was David mentions about Tucking the Children In (Face Hugger Emryo's)  and the Advent Viral about all he needs is to Perfect his Queen.

To me this hints they are maybe thinking of using Daniels to some degree for David to Perfect his Organisms...   David was limited on Planet 4 with Dr Shaw.... but the Covenant Ship David has Technology that he could come up with some more Inventive ways to Perfect/Procreate his Creation.

Great point Bigdave I think with the Disney purchase we will not get any mind blowing gruesomeness  which fans adore. I think it will be some lame, CGI, rushed scene or plot device. I think Alien is doomed under Disney forever. 

The Bathsheba  is interesting because this loosely is something i was going to explore in the latter part of my Alien: Ascension Movie idea

A incoming Human Ship would have on board a Synthetic Construct Female...  Part Organic, Part Synthetic and David would indeed see her as his NEW Love interest and David would be able to Persuade her to see his side of the Story much like how Lucifer Persuaded Eve to Eat from the Forbidden Fruit.

A Hubris occurs when via Engineers she is captured and Evolved into a Bio-Mechanical Hybrid, using Davids Experiments on her...  SHE would be the Source of the Bio-Mechanical Xenomorph which would be revealed in the 3rd part of the Alien Covenant Story.

Alien: Absolution

I do think the Themes of Creation shown in Prometheus but in many Mythos do show that Sub-Creating leads to Hubris, Rebellion of Creation against Creator...  Son against the Father, the Prince against the King.

And so indeed Davids creation leads to his Downfall...  but i was then to explore a Redemption for David... where he gets Revenge of the Race above the Engineers and Prevents his Creations from Invading the Galaxy...

He causes the Space Jockey Incident and also the Destruction of LV-223.

Critters5

I really don't like my idea as it is not very original. But neither was covenant.

Yea covenant was the movie with most blown potential since the SW prequels/new triology, Ghostbusters remake and Indy 4...

Critters5

Well at least, I have seen those other things on tv, so no love lost there, as there was no interest from me either...

I really didn't think Daniels was going to be in Alien:Awakening anyways.  Just look at what happened to Shaw in Prometheus and just look how different Alien: Covenant was when compared to Prometheus.  I think Alien: Awakening is going to be vastly different then Prometheus and Alien: Covenant, which means Daniels will be killed off like Shaw.  This really isn't to big of a surprise.

Just my opinion but killing Shaw was a major mistake for AC.  You can dream up a lot of stories of what to do w/ Daniels but another time jump like what we say in AC is probably the best hope for Awakenings.  I just don't what to deal with David but you need a good bad guy in any movie and that means a new character.  I also think Disney will go in a different direction in the Alien universe if it goes at all.

A Time Jump is very likely for the following revealed Plot by Ridley Scott.

*The Covenant will be going to Origae-6 and RS hints that the Ship Will Arrive at its Destination.   The Covenant is 7 years and 4 Months away from Origae-6 which means at the end of Alien Covenant and unless David goes back to the Surface of Planet 4 for a while...  The Covenant will Arrive at Origae-6 at around April 2112 some nearly 10 years prior to ALIEN.

*There would be 3-4 incoming parties (to Origae-6) and one of those are the Engineers who return to Planet 4 and Discover their World has been devastated and they will no doubt be after the Culprit.  So Engineers will set down on Planet 4 and then be heading off to where David is going.

These Leaves us with TWO things to look at..... which effect the Likely Time Line..

1) Will we get a movie following David Alone on the Covenant Ship or even awakening a few Crew and Daniels and conducting Experiments and what ever other Shenanigans DURING the 7 year plus Journey?

2) Do the Engineers Turn up within a few months or years? How would they detect where David is going... the Further the Covenant is away from Planet 4 the less likely they could pin point which ship is the one they are after as i am sure if the Engineers could search for nearby Human Ships then the longer David is away, the Larger the Radius of Search from Planet 4 would be and more likely they would detect more than ONE Human Ship..  so then its which to they intercept?

If they arrive while the Covenant is not to far, we can SAFELY ASSUME the Covenant would be intercepted in NO TIME and what kind of Movie is that?

Ridley Scott says there are incoming Parties in Context to after David arrives on Origae-6 and so its likely the Engineers arrive at Planet 4 many years latter, at least 5 years after, maybe it could be 10? A lot depends on the Speeds of the Engineers ships... but i think they arrive at Planet 4 after David has began setting up what ever he is doing on Origae-6 and the Engineers find out where David is off to via Walter.

So its highly likely Alien: Awakening happens between 2112-2117 certainly after 2112 and certainly a few years before 2122 (ALIEN) the Sequel that i was working on.... would be set in the year 2114-2115

BigDave I hope that at least they let go of Walter, I really do, one MF is more than enough. Also the engineers do not know how to repair robots (as they do not know binary logic), and Walter has not taken courses in ancient human languages to decode the Engineer language, even if he repairs himself.

You raise a Valid Point...

Again i think it shows the Problem of not thinking ahead of Alien Covenant when they was working on this Project so as to link to the next movie with FEW Flaws..

I think the Question in Context to Walter is.....

How do the Engineers who return know WHO did this devastation and HOW do they know where David is going?

I am not sure the Engineers could Repair Walter, and the (do not know binary logic) addition to our Engineers History is really another way they have backed themselves into a Corner.

IF we assume they return long after David has gone, and discover Walter and he is Totally out of Commission, The Engineers would look at him and would they realize what he was.. have they seen such a Synthetic or Robot before... have they created such in the past?

IF the answer is NO, they would then also notice the Humans that are dead (depends on the state of Decay by the Time the Engineers Arrive)  If they know WHO Humans are, or can recognize the likeness from Walter and then see the same Uniforms/Badges that the Human Bodies have and can Put TWO + TWO together... so THEY figure out/know that Humans had been there...   SURELY they would be off to EARTH or maybe other Worlds that are closer that have Humans (if any are closer etc).

IF the Engineers Can-Not figure out where these intruders had came from or can not make out the Race... then they would SURELY check out the Crashed Juggernaught, where they would see the Hologram Recordings and notice the Humanoids (David and Dr Shaw) at the VERY least they would determine this Ship came from LV-223 and so even if they are NOT aware of LV-223 or what it had became, they would surely go off to VISIT LV-223... 

UPON arriving at LV-223 they would maybe be able to Determine what the Intention was here and about EARTH...  Maybe they could even determine Earth was a chosen Destination of the Juggernaught before it was taken from LV-223 to Planet 4/Paradise?

So i think any Returning Engineers would likely be OFF to Earth or LV-223 and then Earth.  Because i cant see HOW they would know the culprit for the Destruction of the City is heading to Origae-6

UNLESS they arrive while David is not so far with the Covenant and the Covenant happens to be the closest Ship to Planet 4 when the Engineers Return and so they go off to Intercept that Ship....

THIS then raises these points.....

*What would be the Outcome of a Engineer Ship or Ships Intercepting the Covenant Ship in Space... what kind of a Movie/Threat would that make to the Engineers and what chance of Survival does the Covenant and its Crew have?

*Do we assume the Engineer Ships Travel not very fast and so they Can-Not Catch up with the Covenant by the Time it Arrives at Origae-6 and then, how long after would the Intercepting Engineer Ships arrive at Origae-6.

So i think the SETUP leaves us with WALTER as being the Source to where David is heading, likely Walter will not speak Engineer, but if shown the Engineers Navigation Systems.. Walter could likely point them in the right DIRECTION.

I see little other ways the Sequel can bring back Engineers to arrive on Origae-6 other than by PURE Luck or Coincidence.

No Alien 5 please, I am not interested in another Ripley movie. I understand that some people like Ripley and I think that she did fine in Alien 1 to 3 but to me she is done. Her ending in Alien 3 is fitting and I am very much against that they erase that.

I am not very interested in Alien Versus Predator. None of those movies have been very good although I have only watched AVP, not AVPR.

"I think a AVP Reboot is more likely at the Moment."

Another way to say that Scott and Fox effed it up. Maybe a spin-off but let them hire a director with interesting ideas (keep Scott out, I am tired of his David thing) and maybe do a spin-off about Humans and Engineers. They probably can not make it worse than they have already with AR and the prequels even though Prometheus was OK. Get some writers that can write Human characters and a director that gives a damn about that or else forget it. No movie after Alien 3 is better than a 2 out of 5 to me.

"… with a Space Fairing Humanoid Race…"  

That could easily be misread as Space Farting. ;)

In space no one can hear you fart. :D

" … others Do-Not want to be left with the Lingering Truth that David Created the Xenomorph."  

No more prequel if it will stick to that crap.

"… this would be so much of a David movie and no Characters…"

No thanks, I have no interest what so ever in a movie like that if it means another movie where they just focus on a mad robot. I can not feel anything for a psycho. To get a bit emotional: they can take that shit and shove it. I want a good prequel not one that is like Prometheus or AC, can't we at least have one good prequel, or is that too much to ask for?

"… covenant was the movie with most blown potential since the SW prequels/new triology…"

That is interesting that you would mention that, I am not a huge fan of those either. SW episode 2 and 3 are alright but 1 is not good at all. AC and Prometheus are like the SW prequels in quality. Alien 1 to 3 are like SW 4-6 in comparison which is a good thing according to my way of looking at it.

"What kind of a World would David Create?"

I am not very interested in that

"Movie will be less Xenomorph and Focus on AI"

If they make new monsters and replace the Xeno with that then OK but they must work in the context of the movie. What kind of AI that means is not certain but if it means more David androids then no thanks.

Seeing how the Engineers will respond to what David has done could be interesting. Hopefully they will do something gruesome to him which would make the head-ripping in Prometheus look nice.

"… a lot of Fans are not pleased on the David Story and the Plot being about him and his Creations."

I do not like that at all, that is a big mistake that the prequels have done this far. I also do not want another David versus the crew kind of thing, we already had that in Covenant at the end and that was eh.

IgnorantGuy: I liked to see the difference between David and Walter but I agree that it was a bit too much of Fassbender and it was definitely too much androids talking about things. Hopefully we will get better characters the next time and that they will be given more screen-time so it will not be as much about Fassbender and David. Yes he seems to be a good actor but there are also other people and characters there that deserve to get bigger roles instead of being given third place or what ever (being pushed into the background). Give us better human characters and less androids.

Nooo way they would get the information out of walter where the covenant mission is heading. Killing of Shaw was RS biggest mistake.

I think its one of those Writing Flaws, where they have Written Themselves into a Corner..

We have to ask HOW else would Returning Engineers know where to go to find the Culprit....

All they will discover is...

*Devastation of Planet 4 and Potentially know the Bio-Weapons the Juggernauts had was the cause.. But would this not lead the Engineers to go off to LV-223 First?

*Dead Human Body's and Uniforms, which even if they are in a state of decay by the time the Engineers arrive they would discover Walter too who would not be decayed and IF they recognize the Human Likeness they would then surely be heading to Earth or the Nearest place that contains Humans.... and Origae-6 would not be this place.

*Walter... which i described above... assuming he is Dead as a Dodo..

*Crashed Juggernaught with the Hologram Recording which would surely show them Humans (Human Looking Synthetic) and link to LV-223

So its likely the Engineers would thus check out LV-223 or Earth...

Unless...... The Engineer Ships detect the Covenant ship being the closest craft to Planet 4 and putting 2+2 together....  but this depends on HOW close is the Covenant when the Engineers arrive back and HOW fast can the Engineer Ships Intercept the Covenant?  I would Safely ASSUME the Engineer Ships could get to Origae-6/Intercept the Covenant way earlier than the Covenant would reach Origae-6 (7 years 4 Months).

So as far as the Plot and a Shoe-Horn Plot Device... i can only see WALTER as providing the way..... Unless David leaves something on Planet 4 that Plots/Shows that Origae-6 is where he is heading.

But this is just a Logical Guess by me.... WHO knows what the Writers have Planed and with Logan who knows what the Hell that could be as i think Logical could be something Overlooked.

The other Alternative is the Covenant Badges...

But this is FAR more Ambiguous and Difficult to Pin Point a Star System, than even the Prometheus Star Maps. I just cant see Engineers looking at these Badges and going.... I know where that place is.

BigDave Well what I also think on what budget does Scott receive. Maybe if he receive let's say 50-60 million he could completely eliminate the Engineers.

And the more I think about I really think they would have go for the David hijacked Walter's body, for being organic and all, so David could get facehugged. And if go for the fact that humans are merely machines, then even immortality/resurrection could be achieved with enough bio-tech (probably not in the real world though).

And who needs logic in a Sci-fi movie? Nobody cares about that anyway.

Chris10an Damn right it is.

It appears Logic is overlooked... for some its simply not needed and pure oversight....

I cant really think of a way that by Coincidence the Engineers arrive at Origae-6......   I really hope we dont see that Origae-6 is a Engineer World by Coincidence... and Engineers arrive at Planet 4 and then go "Oh ^$&&%* we best rush to Origae-6 as thats our next closest outpost and we cant let the same happen to that"

The Problem with Finding Walter would be HOW can they communicate with him, it would be a bit of a Coincidence if Walter also learned Engineer, so to a degree it would be hard to explain HOW they would get any information off him.... but i think if Presented with a Star Chart he could Point Out where Origae-6 is.

If the Covenant will take 88 Months to get to Origae-6, the Question is HOW many months has the Covenant Traveled by the time the Engineers Arrive?    If its a year or so... and the Engineers can detect a Human Ship thats 1-2 years from Planet 4, the Problem is HOW can they be sure its the RIGHT Ship because well Earth appears to be less Distance than what the Covenant would cover in 1-2 years so there is a chance within that Radius from Planet 4 that the Covenant being the only ship within 1-2 years (Covenant Speeds) is well very much a Coincidence.

Regardless if we assume this, then we can assume the Engineers would intercept the Covenant way prior to Origae-6...   If they arrive 5-6 or more years latter, then  within that 5-6 year radius  i think its unlikely the Engineers could Pluck Out which ship would be the RIGHT ONE.

So it may have to come from any Clues left behind... which are the Wreckage of the Covenant Drop Ship.... the Body's and Uniforms of the Humans and Walter....    But all of these would only draw the Engineers to Earth... unless by Coincidence Origae-6 is the next local World they seeded Humans.

The Juggernaught would lead them to Earth, or LV-223.....

So its a bit of a PICKLE for just how any returning Engineers will eventually narrow down that those responsible for the Destruction of Planet 4 are off to Origae-6

It will be interested to see how the Writers had a way (if they bother) to explain just this... but likely yes we will have pure Coincidence and things that they feel no need to explain or add up...

BigDave let's consider that

1. they might cut the Engineers for budgetary costs / there is no sequel, so they not need to worry about logic. (As I said already the lack of inner logic of BR49 bought that movie quite a bit down for me).

2. If David swapped bodies with Walter, maybe only the disabled body of David is there. So the engineers might need a human to activate it or other human left over tech (we have a human corpse who had experience with repairing androids). But maybe there are 2 Davids after the fight one which left with the Covenant and one which remained and might he is remorseful of what he has done (I hope that this is not the case - one MF is more then enough).

3. David needed at least 2 years of linguistic lessons to deduce/understand the language, but Walter has no prior knowledge of linguistic so trying to decipher the language is a tad of a stretch.

4. Maybe the engineers have some recording tech and they recorded where the ship was heading to so they might deduce the final destination. (Quite a non-explanation!)

5. Maybe they go back to earth bomb it and find out after years of study of the final destination of the Covenant, but the could no possibly know of the Planet 4 detour, so this point is not very logical.

 BigDave furthermore, Walter could no possibly know if he would save his "love" by revealing the location of Origae-6, as the Engineers will likely kill everything with discrimination. So it might be someone more bent on vengeance .... I also think the engineers would think about Walter and see him as a mere toy, so I don't think they would try to fix him if he has been deactivated.

If the Covenant will take 88 Months to get to Origae-6, the Question is HOW many months has the Covenant Traveled by the time the Engineers Arrive?    If its a year or so... and the Engineers can detect a Human Ship thats 1-2 years from Planet 4, the Problem is HOW can they be sure its the RIGHT Ship because well Earth appears to be less Distance than what the Covenant would cover in 1-2 years so there is a chance within that Radius from Planet 4 that the Covenant being the only ship within 1-2 years (Covenant Speeds) is well very much a Coincidence.

Isn't it funny how close to Earth Planet 4 was and yet it passed undetected? 

This doesn't seem right. Planet 4 cannot be the home world of the engineers, rather another planet they seeded as they did on Earth. If they wanted to tell the hominids where did they come from why did they not left the sky map of planet 4 instead of LV223?
