Prometheus and Androids

I posted recently my thoughts regarding one of the stills from Prometheus showing Vickers/Shaw in a cryotube/scanner with a hand in frame. Originally I suggested that it may be Shaw (Rapace) inside a cryotube with David's (Fassbender) hand on top, hinting that the android David may secret harbour sexual feelings towards her, as possibly hinted at in the recent HQ picture in the ampule room. Now although the above may or may not be true, I remembering the stills of Vickers (Theron) going "psycho" (closeup and crouched in a doorway) and the still of the display mentioning an abdomanial scan, I am inclined to believe that David may harbour sexual feelings fro Vickers instead. Of course there is the possibility that David has such feelings to all women. Add to the mix the possibility of a second android, which many have theorised could be either Shaw or Vickers, and it all gets a little complex. Personally I believe that Vickers could be an android when taking into account her seemingly "highly professional" look that somewhat mirrors that of Ash in Alien, which I assume deteriorates after the scan of her abdomen (the psycho pics I mentioned earlier) and leads to some form of transformation (human/xeno/Space Jockey/other). The more and more I think of the roles of the android(s) in Prometheus the more I wonder which aspects of these characters we will see.
