Some of you are not understanding the return to colony ending.

You are going back to the colony to die. Raven flat out tells you this. MS isn't going to have you spreading all those secrets she works her ass off to keep. Eve will be mind wiped (we know all andro-eidos have a usb stick that holds all their memories.) Lily will die. MS will just copy past Eves build for her next generation. That's the end of the line.
