1. being Urobuchi scripted, a major character will die
2. with the rescue beacon always on, could the Hideous follow and reach Earth later?
3. would not be surprise Hideous is a human creation.
4. the Avalon sounds like a very tightly population control structure, due to the limited space/resources, as one of the right of being citizen is "right to populate",
5. would not be surprise the fight against Hideous is the way Avalon control its population, that they launch a major offense whenever a group of human reach citizen age.
6. So Earth, the defrost water planet, is literally the last heaven/Eden for Avalon human, if they only knew it, or do they already know but the computer/few human is withholding the knowledge from the masses?
7. but why is Earth frozen and lost to human in the first place, is it Hideous related?
8. would other "being" follow Ledo to Earth through the wormhole concurrently? both the Hideous or Kugel?
9. the mecha "machine calibre" would not be invincible, one of the plot device would be it can run out of energy.
10. would Chamber be deactivated or turn against Ledo at some point of the story? especially after Ledo learns the truth of Avalon/Hideous/Earth?
11. is it me or isn't there some Galatica vibe? Water World? Nausicaa?
