Questions about Mila, our beloved.

Was Mila originally just another Mita who survived for so long to gain knowledge about the game's lore and versions of Mita, and chose to be different because of it, or was she originally coded as Mila in the first place?

Does anyone know what her bad blood with Crazy Mita that resulted to her solitary confinement?

And would the respawn & reset mechanism apply and make her basic again as good ol Mita if becoming Mila was through her own long development? CMIIW
