Multiple system stuff
As open as I am about the multiple personalities stuff here, I try and keep it to the Practical.
Some days though, Yaori is bouncing around in our head and she's something so improbable that Keri keeps subjecting her to Voight-kamph style testing to make damn sure she's not a freudian construct or Tulpa or false-flag evil spirit.
And she's frustrating, because Her understanding of what she is leads to a lotta questions having a 'Well, Yes, And..." kinda answer. Or it's along the lines of 'Well, nobody told me I couldn't use your subconscious as a radio transmitter to get into other people's dreams'
So it's a bit different than most of the plural folks I know here.
