REI'S VOICE:“Who am I? What am I? What am I?
What am I? What am I?”
Dr. Nick: Even though Rei has the soul of a progenitor superbeing, it's no wonder why she's so confused about what she actually is. She's gone through soul-splitting once, and furthermore, the mechanism by which her soul is transferred from one clone body to the next is implied to be pretty gruesome corpse-grinding affair as well, so there is a lot trauma and existential horror to go around.
