Regarding Flutterina, I feel like they could always do a story explaining the events leading up to her death or maybe an origin or something so it's not like her character can't be revisited just because she's dead.
Anyhow, what do think about the idea of Despara getting these memories/glimpses into her future self as She-Ra due to her bond as a twin? You know, like maybe she sensed the disturbance in Adam.
btw, the story on CNN has almost reached a milestone 2,000 recommendations of Facebook! So exciting.
