Vickers: "Lets say I'm wrong, and you do find these beings down there..."
Holloway: "Miss Vickers, is there an agenda that your not telling us about?"
Vickers: "They were right."
Janek: "Did you want
them to be wrong?!"
My money's still on Vickers being some kind of goddamn Succubus! (Tree-Fiddy!)
Veronica - The Succubus!
Vickers?? Giger Alien Monster IV
The "Take us home" plea from Vickers is surely the big give away to her odd character because it appears that moments later she is seen jettisoning herself
to safety! My guess is that she rigs the Prometheus on a collision course with the Juggernaut - I am presuming that Janek only intended to follow it and shoot it down?
It would be too boring if she was simply an executive mole or an Ash-like android. She clearly already 'knows' abouth the Engineers and perhaps what caused their extinction. I'm guessing she is returning to finish the job. Perhaps she is the Engineers' Nemesis, or part of some kind of galactic Opus Dei, or maybe even the devil incarnate?!
She is definitely a 'suit' for something - but I seriously doubt that its anything human.
Vickers' agenda could very well be the most intriguing part of the Prometheus story.
