SPOILER from Hollywood reporter

I thought this might clear up the nebulous pic of maybe David lieing on the floor headless. I don't think this was ever mentioned. Sorry if it has then please block this: A third sequence shows a cave-exploring couple, Rapace and Logan Marshall-Green (Devil). Their flashlights illuminate primitive drawings; in one, a human figure points toward spherical objects in space, leading Rapace to observe, "I think they want us to come and find them." Then, in a scene likely to be memorable, the severed head of an android speaks as it lies on the floor. It's the moment most reminiscent of Alien and Ian Holm's decapitated robot. A sequence with a ship hurtling on a collision course with another ensues. Finally, there is a riveting moment in a cavernous corridor when Rapace and her colleagues encounter giant humanoids -- made of shimmering lines that resemble X-rays -- who race toward them and pass straight through, as nebulous as neutrinos.
