Wow.
So it looks like we can add more weight to that Dr. Moreau vibe.
There are lots on implications here you guys!
Think about it:
These photos either mean, David has somehow had people to experiment on before the crew of the COVENANT arrives. Or... This film takes place over some time, because this set indicates somewhat extensive time has passed.
Hicks was right. It is reminiscent of the 'Ripley finds her clones' scene in A:R. Which was supposed to have been taking place over time, BEFORE they scientist got her cloning process right, and before the Betty arrived. Right? So what does that mean? How did David obtain the specimens needed to perform these experiments? Or does the crew of the Covenant spend a considerable amount of time, unaware of his, experiments as people go missing?
Or is he using Shaw's body somehow?
Eggs imply a queen, as well. No?
So there is a lot going on here, eh?
Let alone the idea that there is an Engineer temple where David is performing these experiments and when you combine it with this idea of air-born spores and the other leaked images, a full film is starting to take shape.
Which brings me to this - The drawing immediately to the right of the bust, I do believe this is our AIR-BORN SPORE.
