Alien: Covenant

Continuity mistake: Daniels' face gets splattered with blood but when she uses the radio to call back the others, her face on the screen shows no blood. In the other shots after it's there again.

Continuity mistake: Walter near the beginning of the film, is going over the ship's systems. He checks the fetuses inside a compartment and sees a dead one. As he removes it, the slot it came from is full of blood. He places it inside a container. Then as he hits the button to close the compartment, the slot has no blood in the next shot, and no implying he cleaned or decontaminated the slot. (00:08:00)


Plot hole: The computer on board the ship mistakes David for Walter. This makes no sense as while a human being could be fooled by his appearance or his voice, a computer with detailed sensors and possessing the exact details of David's composition would not be fooled simply because the two "look" and "sound" alike. In fact, Walter, being a newer and more advanced model, should be composed of different chemicals and materials than the earlier manufactured David making it even less likely that the ship's computer would have mistaken the two.

Suggested correction: Makes way too many assumptions about the manufacturing of either one.

Furthermore, we do not no exactly how the ship is supposed to be identifying the androids in the first place.

I feel like I already corrected a similar mistake. David is less advanced, but cleverer than Walter. The correction is right in saying there are too many assumption being made. Who knows what David did to be more like Walter, that might even be easy for a highly advanced android. Who knows how advanced and sophisticated the computer sensors are to detect an imposter android. I didn't think the computer or anything much is made with many defenses against sabotage. Its a peaceful universe. Also don't really remember but the first time David enters the ship couldn't he already have modified the computer? Hacked it?


Well, we do know that Walter is constructed much differently that David. David uses what he thinks is an android-lethal move on Walter, and David thinks he has killed Walter. Moments later, David is astonished to see Walter not only alive but ready to do battle again. At this point, Walter even says, "There have been a few upgrades since your day." Which means that Walter is different in ways that even David didn't imagine. So, the original post is correct: Even a cursory security scan of David would have instantly revealed that he wasn't Walter.

Trivia: The synthetic androids in the whole saga are named in alphabetical order in Alien Ash, in Aliens Bishop, in Alien: Resurrection Call, in Prometheus David, then Walter in Covenant.


Trivia: When David is cutting his hair, he is singing, "The Man Who Broke the Bank at Monte Carlo." This is a reference to the film, "Lawrence of Arabia." In Alien: Prometheus, David had a fondness for that particular movie and emulated Peter O'Toole, who played T.E. Lawrence. In the movie, Lawrence sang that song while riding on a camel in the desert.

Trivia: The drinking water duck device is shown in almost every film of the saga.


David: Look on my works, ye mighty, and despair.

David: Serve in heaven or reign in hell?

Elizabeth Shaw: How long?
David: Impossible to say.
Elizabeth Shaw: What if they are not better than us?
David: So long as they are not worse.

More quotes from Alien: Covenant

Question: During the movie we learned that David felt some passion for Elizabeth for being kind to him before. So why use her body for his experiments after her death? Surely not to learn about human anatomy, which should be known to him already.

Chosen answer: Regardless of his android passions, David was already experimenting with the bio-goo, and he deliberately used it to impregnate Dr. Elizabeth Shaw with a proto-face-hugger in "Prometheus." In "Covenant," we learn that David later killed Shaw and is experimenting with her body because her body tissues contain human-alien antibodies that are essential to David's work (which is creating a new generation of xenomorphs).

Question: Why does David use his real name at the end instead of Walter's to gain access to the colonists and embryos? Wouldn't that been noticed in the log or something? He is pretending to be Walter in the first place and with the last log entry he uses the name Walter.

Chosen answer: It doesn't matter anymore at that point. He has full control of the ship and can change anything he wants. Including the logs, if it's necessary.


Question: When we see the eggs for the first time did they come from an actual Queen, or did David use Shaw's reproduction system to create them?

Darth Crucible

Chosen answer: If there had been a Queen, David would not have just left it there on the planet, he would have taken a Royal Facehugger embryo with him on Covenant. So the latter is most likely correct.
