Comment by Azuleen on Evolution Begins With A Big Tree - Chapter 20

@Azuleen From what I get the one is in a sleeping state and the other is dead, but the dead one's soul is still around controling the body of the sleeping one

@Fellemir Fellemir No. It was perfectly specific that the one with the body is dead, and the one who is a soul's body has died. So the soul is controlling the body of her dead syster. Essentially, a new being(?) was born of the fusion of the remaining soul and body.

@Insight  
Uh no it was specifically stated that the one with the body is still alive. If she weren't then the one that turned into a spirit could not control her body.
