That all said, Alien: Covenant did do its job admirably well: combined with the events of Prometheus, it tells a comprehensive enough story for diehard fans to connect the dots of how the xenomorph species came to be, and how the stage was set for the events of Alien (1979). Interestingly enough, there is a scene in Alien: Covenant that speaks to a key point in the franchise’s timeline, and makes the events of the new Alien: Earth TV series even more intriguing.
“Idle Hands Are The Devil’s Work”

The big twist in Alien: Covenant is the revelation that a character from Prometheus, Mr. Weyland’s first android prototype, “David” (Michael Fassbender), not only survived the first film, but diabolically murdered his human companion, Dr. Elizabeth Shaw. David used an alien ship to find his way to a homeworld of the Engineers, the advanced species that terraformed many worlds and seeded them with new forms of life (including Earth), using the “black goo” mutagen they developed. David turned the Engineers’ own weapon against them, wiping out their homeworld before setting up his own genetic research “lab” there, where he spent decades messing around with the mutagen, infecting various hosts until he found the genetic combination for the facehugger parasites and their eggs.
When the crew of the USCSS Covenant stumbles onto David’s world, certain crew members are quickly infected by the mutagen, resulting in several xenomorph variants (Praetomorphs) being born. The Covenant crew is forced to accept refuge from David, not knowing how dangerous the unhinged synth really is. David manages to pick off team members one by one, while also birthing a xenomorph drone, but Covenant‘s synth officer, Walter (also Michael Fassbender), catches on to what David has done and confronts his “brother.”
Synthetics Were Originally More “Human”

One of the more telling subplots of Alien: Covenant involves David invoking a quote from the classic sonnet “Ozymandias”. David attributes the work to the famous English poet Lord “Byron”; however, later on, Walter points out that the true author of “Ozaymandias” is Percy Bysshe “Shelley.” David’s error is exposed as proof that his programming is dangerously corrupted.
