Дэвид и Шоу нашли причину истинного зла. Дэвид и Щоу решили нанести по этим лысым превентивный удар, чтобы те не полетели с миссионерской миссией на Землю
What if David and Shaw went to Paradise, Shaw found out about the Engineers and their Hierarchy and the True Evil Agenda and how Wicked these beings are.... and David then unleashes Hell on them.
Shaw finds the True Horror of these beings and how they have set up Shop on other Worlds, and so David managed to convince Shaw that they can make a Covenant to join Forces and set out on a Mission to Rid the Galaxy of these beings so they can not pose any Threat to Earth, maybe David can fool Shaw that he actually has respect for his Creators and Life that he was given, and that he was angered because those Engineers also tried to kill him.
So they go and Destroy the Engineers or whats left on Paradise, David then Teaches Shaw how to fly the ships and they take another One from Paradise (that maybe has a different effect Bio-Weapon? or maybe not).
They then set off Bombarding Engineer Worlds, and they then arrive at Planet 4: And do the same...
