David MIA

During the critical action sequences David is MIA. He is not shown doing anything until he contacts Shaw in the escape pod. After 11 screen time minutes he 'appears' in Shaw's headset and procedes to give her critical instructions. Hmm ..he is on board the Juggernaut heading back to earth and somehow is all knowing about what is happenning after the Juggernaut crash. What should we expect David to be doing during this Juggernaut flying time? Was he still recieving data feeds from Prometheus and remaining crew members? He mobility obtions are very limited, Did he try to connect with The Last Engineer and talk him out of Earth destruction? Could he even have tapped into the Juggernaut's data base and anticipate the Engineer and Ship's actions? Or did David just let the story just develop and see what happens? David must have done something with all of the info he had or was recieving. It is not like him to just be still. And why did he wait til after the crash to contact Shaw? He was experiencing what was going on in the Juggernaut and may have provided Shaw, Janek even Vickers with helpful information to ensure their survivial. Having 'spy' in the enemy's camp would certainly be an advantage in any wartime senerio.
