Is it Walter or not? Daniels (maybe) checked it, when they were on board.

Well something we have to consider (if we accept this not as a movie but a real events) is after the Wheat Field Attack to prior to David vs Walter Fight, there would have been more scenes and time where Daniels would have spoken to Walter and not doubt noticed his Hand.

So its safe to assume when Daniels notices the Hand this would have put any doubts (if she had any) to bed so to speak.

The game was only up when She talked about the Cabin on the Lake and David had no idea about this....

some could wonder and its open to interpretation as if this conversation just naturally happened... or if Daniels asked this as a direct way to confirm if it was Walter.

I dont think this was the case because its a dumb move by Daniels... if she had doubts, she should have asked a few Questions that only Walter would know the Answer to... before she went into Cryo-sleep.

Daniels showing she now knows David is David and not Walter was a huge mistake.

The secret is out now and whatever small chance she had of surviving cryosleep has probably gone.

She should have never got in the cryosleep pod until she was 100% sure it was Walter onboard.

I agree i would have had the scene end where she has no idea...

Then as David regurgitates the Embryos have him hold one to his eye and look at it with a smile... and say "Big Things have Small Beginnings"

However the way they did it was a bit clever... but it now does mean Daniels would be a Thorn to Davids plans and no doubt he has to get rid of her... lets hope its done in a good way and no Hicks/Newt and Dr Shaw way.

It was Walter's chassis (body) with David's programming (software) in it at the end of the film.  David had a wound to his chin, and Walter did not.  Some people say that Sir Ridley stated that it's actually David speaking to Daniels at the end of the film.  If so, Sir Ridley must have changed his mind after the film was distributed as he often does.  It's just too bad that he allegedly says things that don't match with what we saw in the movie.

The Novel also indicates its David at the end... and while we can still have theories on this being David within Walters Body.

I think the way they ended the movie is a direct hint to show is this is David... the only way then it could be Walter is David uploaded himself and it overwrote the Walter Software so David would have none of Walters memories etc.

I think the scene could have been handled differently instead of a Fight.... it could been Walter tricking David to use a Device to give him a Maintenance/Reboot... but this backfires and David uses it on Walter or in a way to Transfer his Soul to Walter so to speak.

But hinting at this would mean the Fans get to know the Reveal/Switch at this point and so it would not be left as a Twist at the End.

Apparently there was about 3 Alternative Endings, but all showcase this was David just they ended in different ways.

The Novel also does show that David has Healing Abilities as Daniels Stabs him in the Eye and his Eye Heals up. (does not stab him in the Chin).  So maybe David has limited Regenerative Abilities.

But indeed as there is this difference unless its explained that David does have Regenerative abilities to a degree, then its open for debate.

so the David uses Walters Body theory is something that can be debated, despite what RS had said.

I curious about all this discussion about David using Walters body or downloading Walter's memory into David.   Would David really have had the time to do this considering the fact fact that they were quickly going to evacuate the planet?

Thank you BigDave for share with us this information "Regenerative abilities", but not applicable in Walter who does not grow his arm.

I think Walter's regenerative abilities are just the synthetic skin and surface tissue, which can regenerate, not the solid structural stuff, like the synthetic "bone" framework of a hand, which is probably alloy, plastics/polymers. The WU specs on David 8 say "Major repairs or physical damage must be addressed through an authorized Weyland Cybernetics facility". It also says the David 8 skin is polyurethane, so I assume that cannot heal.

Too bad that they didn't put any of that in the movie, eh guys?

Sigh...

Just another one of the gaping plot holes this movie has...This one in particular is the predicatable "switcheroo" ending. 

I would have much rather had Walter "turning coat" on the crew because he has been indoctrinated by David than this trite about David overcoming Walter in their battle, making himself to look just like him, cutting off his hand, picking up all Walter's mannerisms, and generally boring the crap out of all of us.

Sorry to be so negative, but I haven't had my morning coffee yet...I'll spank myself later...

How many of you thought the reveal that Walter was David was actually a "reveal"? I thought they made it obvious this was David all along and were not even trying to hide it. The three people I saw the movie with with felt the same.

It seemed clear the first time they showed Walter after the fight that he was David. David's facial expressions made it obvious - he was smiling when the alien was loose on this ship! If the film makers did not want the audience to know, they would have had David act like Walter. But they were not even hiding it.

They only mystery I thought about was, are any of the crew going to realize it?

The biggest tell for me was the unhealed cuts on David's face. Walter would have regenerated already.

How do you know that? Was there something in the movie indicating the speed in which it heals, or that it heals?

He was shown to heal very quickly in the fight between him and David. There was some dialogue early in the movie too, or maybe it was one of the pre-release video clips.

The only dialogue in the movie was "There have been some upgrades since your time" from Walter. Nothing was said about healing, and Walter did not heal during the fight. He had cuts all over him that were leaking.

There is some clarification of that in the promo material for Walter, stating that his synthetic skin will heal. It could be assumed that David has some similar capability, but maybe slower, more human speeds, which would explain why he needs his face stapling.

As for the hole in his chin, he could have found a way to disguise it until he could find a way to heal it once on board the Covenant...
