It was Walter NOT David

---- You drank too much yesterday then you had sex with an android, but the next morning you have to face the fact that... It was Walter NOT David! --- Screeeam!!!

Sorry...Please forgive me. :)

No. David pretended to be Walter- just watch the ending. Nothing to debate really.

I do feel sad that we don't really know what happened to Walter and probably never will. Walter was good people.

I choose to believe that Walter's story will continue in Awakenings - I don't think we've seen the last of him.

I loved Walter.

Walter gets repaired by a group of returning Engineers, and teams up with them to stop David! 

Cue epic space battle, 25ft Space Jockeys, Engy weaponry, multiple faction ship designs, all set in a Gigerverse. Oh I hope, hope, hope!

ps ....and some flute fingering....;)

Sadly, I neither hear nor see any evidence of Walter appearing again at this point. I really hope to be wrong.

David just had a frog in his throat when he was lying on the floor. Or was it a couple of encased embryos? Either way, all he had to do was clear his throat.

I can't see David repeating his mistakes. It would probably only take a moment or two to prise out the CPU from an incapacitated Walter to put him well out of action. Maybe if someone re-visited the citadel and plugged his chip back in, we could see Walter again, but a tad unlikely I would suggest.

It's David pretending to be Walter. He's even seen later, patching up the wounds on his face that Walter gave him when he hit him with the rock. Ridley Scott also confirms it's David, in this podcast: Alien: Covenant Spoiler Special With Sir Ridley Scott

Who cares if it's David or Walter as long as it is Michael Fassbender :D

Well its either a lack of thought by RS etc to make such a oversight, that would not add up to latter... i.e his Speech Malfunction... or a clever piece added so that it gives a bit of AMBIGUITY so we may Question is this David or Walter?  So it does give some debate.

But RS had confirmed as Svanya said that it is David.

"Sadly, I neither hear nor see any evidence of Walter appearing again at this point. I really hope to be wrong"

The only Clue i have DK is from RS when he said about David is off to the Planet... we can only assume Origae-6 (could instead be LV-426/LV-223) but i assume Origae-6 and he speaks of 3-4 Parties that would be arriving...

One of which will be the Engineers after they return to Planet 4/Paradise and find the destruction... so it Safe to Assume Engineers arrive there and find out what happens and then they go off to Find David etc.

So we have to ask if David is off to Origae-6 which is 7.5 years away from Planet 4 for the Covenant Ship.... we have to ask HOW DO THE ENGINEERS Find where David will be going?

Do they arrive and then detect the Covenant Ship well a ship, this means they arrive not far after or are able to detect a Ship and think thats got to the be the $£"%£"^£$^ lets get them... but depending when they arrive to Paradise/Planet 4 will determine how far the Covenant is away..

So if they arrive 3 years latter, the Covenant will be like 3.5 years within its journey time and looking how far that is from Paradise/Planet 4 and so it would be say XXXX Light years away.. lets say 100LY then how many other Human ships could be within 100LY too and so how would the Engineers know which Human Ship within XXXX distance is the one responsible?

Did David leave clues to Origae-6 on Planet 4?  What can the Engineers Salvage?

And it cant be the Engineers arrive earlier where the Covenant has to be the only ship close by, because surely the Engineers would intercept the Covenant in Space and that Ends Davids plans..

Nope... David has to arrive or be very close to his destination by the time the Engineers arrive on Paradise/Planet 4

And so we have to ask how do the Engineers know to go to Origae-6? or that David would be there.

The only LOGICAL Answer i have is via Walter. ;)

Darn....Walter was awesome.  

Did the scene on the cargo lifter, when Lope asked "Walter" for a painkiller shot, contain any clues about the android's true identity? I don't know why I was convinced that it should reveal something but after watching it several times I couldn't find anything relevant.

Would Walter have gone to help Daniels fight the Protomorph as he already saved her twice before, from neomorph and from David? I mean he threw her the axe but did not go out.

And he looked a little confused on the cargo lifter, not helping Lope until asked for help, it took him few seconds to locate the medical kit.

I think the first time he shows himself as David is when he smiles like a mad scientist, seeing what the second Protomorph did to Lope on the Covenant. From that point there is no doubt on who he really is.

David lied to Lope when he put the patch on his face. He nonchalantly said "It's fine" when clearly it was not. That was an early clue that an impostor was onboard.

Through the whole Alien series if you have that voice malfunction as an android/synthetic means you're in a bad place. Ridley intended that. By the way RS has a history of saying some things in interviews to distract or detract viewers..

Pretty sure it's David. Plus 20th-century fox shared this image on Alien fb page.
