There are people in this world who will tell you that Alien: Covenant is a bad movie. They are wrong, and you should avoid associating with them. Why would you want to expend time and mental energy on someone who wants to leech the joy of the “I’ll do the fingering” scene out of your life?
Even if you haven’t seen Alien: Covenant, you probably know about the fingering line. In the context of the movie, the scene in question offers up a metaphor for free will. Android David, freed from the shackles of godawful humanity (we suck), is attempting to instruct Walter — a later version of David’s own model, his programming stripped of autonomy after David went AWOL in Prometheus and decided LOL humans deserved to die (tru tho) — in how to create something, even if that something is as simple as a tune on a recorder. Walter will blow the air through the recorder. David will do the fingering. Before long, Walter will be doing the fingering himself. Or something.
Look, just watch it.
1:09 is the money shot.
And yes, in case you were wondering, the two robo-Fassbenders do kiss later in the film. David also says "Welcome to my dire necropolis," which is probably much better than any sex talk you currently use.
Ridley Scott is a mad bastard, and Alien: Covenant is genius.
