Walter may still be alive.

I Moon Girl I imagine they would not trust Walter especially considering being identical to David. It would be interesting to observe Walter overcome that obstacle though!

@dk

True, but did they have time to see his face.  He was really high in the sky too.  If Engineers created humans, then they don't have vision to different than humans.

Of course, these points are based on the idea that David and Shaw were arriving to Planet 4.  If they were actually leaving Planet 4, then they would have obviously known what he looks like.  Then, I could see trust issues for sure.

@ dk

They may not even know that he is human.  Well, looks like a human.

If they know he is a "human", then I think Earth is back on the hit list.  If that word gets out to the space jockey Engineers, I think Earth is doomed!  I hate David...

I Moon Girl David is lethal, as RS said. IDK that the Engineers know the difference based on appearance alone I wish Walter would have come out victorious. Fingers crossed for the next movie. Most movies have ended badly though.

mabye he will come back with the engineers in awakening. it is possible that hte ywould pick him up.

If you look closely I think you can see some grow back on Walter's hand towards the end. Am I wrong? Personally I think it is Walter on the Covenant, despite what RS says..

I think this is a interesting Question...

I have not listened to no commentary, but there are a lot of Questions raised regarding the David vs Walter Fight, a lot of Questions Raised regarding the Regenerative Ability of Walter and David, and we have to assume that they can only Regenerate to a degree.

We have to Safely Assume Walter had been incapacitated by David and was unable to follow him.

Regarding the Engineer Ships as I Moon Girl mentioned, regarding the Ships, we have to assume maybe there was NO MORE Ships or that there is some Reason David could not have taken one. The Concept Work and deleted Scene shows the Hanger has a number of Ships but it was suggested that after the Bombardment the Ships had entered a Quarantine/Dis-activated State.  This is a bit of Bad Writing however, because surely in 10 years David would have found a way to Activate a Ship.

But as we dont see any more in the Theatrical Cut we can not assume for 100% that there are more ships, as this then gives good reason to why David was stranded.

I dont think Walter would be able to use Engineer Technology as well as David because David had learned and Studied Proto Languages that allowed him to Speak to the Engineers. So we could assume without the lessons David would maybe not have been able to understand.... but then also with AC we have to ask how did David know how to play the Piano if this was the first time he was activated?  Something has to be learned by being passed on, which the Flute Scene showed.

We cant rule out Walter being able to learn how to use Engineer Technology etc, given time but a Big Question would be in what STATE of Disrepair is Walter in?    The David that Dr Shaw went to collect would be of no use in TWO Parts especially if they are far apart (Head/Body)

I think Walter is Alive, but disabled as i really think this is the only logical explanation to how the Engineers are able to determine that David has done all this and where David is off to, The Question is how do the Engineers get this information from Walter?

Why people so sure what Walter remained on Planet 4? Why not David? Maybe they concluded a pact... a covenant. David remained on Planet 4 (mb even dead) and Walter accept to David's mission and decided to "rule in hell" - go to in ship on Origae-6.

Remember the SCAR on Walter's face (in fight with David) - we have how he "heal" it on Covenant. David haven't a scar on his face. Nobody saw they battle. There's no reason to make a scar specially.

Why does Walter says David's ID on aboard? Mb the Covenant starship was intended specifically for David! This was a covenant between WY and android. And, I think, what Walter was a new body for David or successor. And (on Planet 4) David told him his own ID. Why? Because a Walter has a better body and more resources.

leto: it cannot be walter on the ship because the give away that he was david was that he didn't know of the cabin on the lake. if it were walter but evil, he would have bean able to bluff to daniells about the cabin. also he requests muther to play the enternce to valhala witch is something that david had a personal connectio to.

id say the only way the engineers can go after David is that they find out where he may be going from Walter. other than orbital tech I don't see how else theyl be able to go after him to origae6

Timmy the ultramorph

Disagree. I think - this is was a Walter. Cabin on the lake? Not argument - Walter just decided not to speak about it. This is meas that Walter accept David's ideas & refused the past "slave of duty". Valhalla - same.

Or it was a David AI in Walter's body. And in AW we will see struggle of two minds. But this also means that David's body is dead.

Or it was a David AI in Walter's body

If they go that route, I would think Walter AI would be in David's body. Walter's wounds healed except for his arm. He was stapling his face near the end. Seems Walter's body would self heal for an abrasion. Walter could have tricked MUTHER by requesting the music at the end- playing the part of David? That way, there would be no suspicion from MUTHER. Then again, the access code seemed to be all that mattered to MUTHER.

The is it Walter/David is something debated a bit before, but Ridley Scott had confirmed that David had disabled Walter and taken his clothes and then cut his own hand off.

I think this is the story that RS/FOX will stick with, HOWEVER.... i cant see Fassbender playing the role of a ONE Handed Android in the next movie, at the very least i suspect David will repair his hand with the use of SPARE PARTS taking ONE Synthetic on such a IMPORTANT mission knowing the tasks that Walter can perform, i would doubt they would not have any SPARES about.

We CAN-NOT rule out however if David is able to actually BUILD a Walter from Parts and then UPLOAD his Memory/Soul into this Unit, i think this is something very possible.

As far as Walter, i think again its likely we may see him or if not, it will be inferred to us that the Engineers came across him, they would discover he is not HUMAN but there would have to be some good reason they dont go to Earth or check out LV-223 as i think they will indeed head to where David is going and i would assume they turn up on Planet 4 a Long time after David has left.. otherwise we could safely assume they would intercept him in no time at all.

I recon the Engineers dont turn up on Planet 4 until David has been on Origae-6 for quite some time.
