David and his plan !

Just thought I would put it out there and say that we all think David has a bigger game to play in this film but how about this: Personally I've been tinkering with the idea that David in his couple of years "wondering" the ship he desires most of all to become Human. His "brain" filling with ideas and passion about this over that time, turns out to be jelousy and his desire to become one of us 100% is changed within the film at some point. Knowing that he can not reproduce another life form himself, he sets out to try to uncover the secrets of the SJ's more so than the others, to extent that, he stumbles across ( not yet known / shown ) in the trailors and either uses this against us or tries to create something to give "birth" but obviously has deverstating consequenses on his Human "masters". We do see him alone in the Starmap room with "old Blue" or several as some people have pointed out, so thus their interest in him sparks it all off as he sees what marvels they can produce and tries to become what he can not.. I think it could be him that enters the SJ chair and becomes one with the ship, thus feeling that he can now give birth by destroying the Human Race and starting the evolution again using the craft as the catalist !!???? Well something along those lines... think you see where I'm heading with this..
