In a memorable scene, David, who fashions himself after aristocratic British adventurers of the olden days, teaches Walter how to play music, holding a flute to his mouth and saying, "I'll do the fingering." Their connection is riveting and, especially in David's case, highly emotional, which makes his question in a later scene-"When you close your eyes, do you dream of me?"-all the more heartbreaking. While the humans run around shooting things and exploding things and getting picked off by the planet's parasitic residents, Walter and David (both played by Michael Fassbender, in a mind-bending technical achievement) share a few philosophical chats about whether or not humans deserve to inherit the legacy of higher beings-you know, robot flirting. In Alien: Covenant, a human colony ship's resident nurse android Walter encounters David, an earlier version of himself who survived his own ship's unfortunate crash-landing on an uncharted planet populated by bloodthirsty monsters. The mangled, leggy forms of the pre-Xenomorphs are too, well, alien to connect with, so who do you root for? The robots, of course. While watching Ridley Scott's Alien prequels Prometheus (2012) and Alien: Covenant (2017), it's impossible not to notice their utter disdain for their human characters, and for humans themselves: a failed creation clawing its way out of the sand trap of inevitable extinction.
