David, Walter and Muther.

Ok so in some of the threads people have talked about this somewhat but i haven't seen any address it specifically. 

We Know David considers himself Weylands Son. we also see him call Walter his Brother. so is it a long stretch for him to consider Muther his Mother. 

We know the Weyland commissioned David, but the AI and tech installed is most likely a version of Muther itself. (all part of the network) David is the first Android, made to be human in every way as much as possible. to a point where people dislike how human he is and replace him with Walter. an android the same in every way but more restricted in his abilities. 

People have asked how David is able to use his own name and codes to access muther. I think this explains why and more importunely why Muther has a very different tone with him then she did the crew which is far more official sounding then with David which is far more a partnership.

Why name the ships AI Muther in the first place. Weyland choose or at least signed off on the name. The mother of his perfect child. makes sense.

Oh i also don't think David killed Walter, burned off his hand and swapped clothes to impersonate Walter. I think he uploaded his AI into Walters body. (the clue being the wound from Daniels Nail not being on Walters body) Maybe david is still in the citadel working through the engineers plans while his is also now on the covenant preparing the colonists for impregnation.

some ask why cryro the face hugger embryos and not just let them lose. I think because more study is needed on Daniels and Tennessee to perfect the organism. Shaws body was only able to be studied to a point. now he has two new victims to experiment on.
