So, if in conceptual theory Dark Samus were to become an Aurora/MotherBrain somehow, that might be an ironic twist since the original Mother Brain was originally Chozo technology (can someone explain where they got that bit of info from), and the Metroids were created by the Chozo, and Dark Samus was a Metroid "Prime" that got all pissy and took out the Chozo's home world?
This is all so confusing? Seriously, it is worse than piecing together the Zelda storyline, or maybe not.
