Thinking about the drama that can occur by effectively having three version of the same character.
Assuming that the woman shown staggering though Living Memory is Sphene, the original Sphene then we have three Sphenes who could be in conflict with each other.
So like we have this woman who is likely the Original Sphene show up and very likely looks, and acts very differently from Skynet Sphene or Fake Sphene. Thinking about she could oppose the use of regulators, and the existence of Living Memory, and how she would be completely unrecognizable to Alexandrians despite being the Original Sphene.
Also
Gonna bet that everyone using one of the black neo regulators is gonna be used to create/summon Necron down the line.
