...you got most of that from me...didn't you. That Cloud is an empty shell, with first Zack's memories and later Tifa's memories powering him. Our story does not begin until Cloud finally absorbs Tifa's memories. That is when he gets a piece of his true self. It was a catalyst of awareness, sole to speak. None of the other clones were aware of their surroundings...they just wanted to be with Sephiroth. That is the only real, reason why Cloud is different from the other clones.
Jenova isn't a Cetra.....it was just assumed. When you go to Cosmo Canyon, you find out Gast may have been wrong. And when you find the tapes at that Icicle village, you find out he was wrong.
If you pay attention to Vincent's story, you find out that Gast was a part of creating Sephiroth. He knew about the Sephiroth experiment. He wanted a reincarnated Ancient, too. Hojo just went a step further...He wanted the Ancient to be his blood. Gast probably didn't know that Hojo had gotten the female researcher pregnant. But that really doesn't matter, that just shows how Hojo thought, and how selfesh he truely is. It's just ironic that Gast turns out to be the true father of an Ancient....His blood was in Aeris.
Of course none of these things really effect that....Brainstorm paragraph? you wrote....
Red13 had only one role in the story....to mate with Aeris so that the speciments that they created would have a long life span..... so the children could be experimented on....indefinitely. As for his cubs....I'm sure the planet is bigger than the game shows it to be...
