The revelation of the deleted scenes, Holloway forcing sex on Shaw, makes me think that the original script of PROMETHEUS may be even darker than we'd like to admit. A near rape of a woman while being infected with alien DNA, isn't this another play on that interspecies intercourse only implied in ALIEN? I think PROMETHEUS would even be more compelling if Holloway in his ego-trip fanaticism actually agree to be infected with alien DNA and then impregnate his own female partner with it. His display of remorse and ultimate self-sacrifice later on would make more dramatic sense. I think that his asking Vickers "to do it" comes out of nowhere, and feel hollow.
