are you sure that the sephiroth clones werent injected with Sephiroths Cells and not with jenova's? Or does it say specifictly in the game that the sephy clones are injected with jenova's cells? i dont really remember.

But if my theory is true. it would explain alot. because, that would maybe give a reason why zack didnt react to the process the way Cloud did. Cause Zack already had jenova cells in him since he was a member of soldier. But since Cloud was never in soldier, and prosumbably neither were any of the other clones, it would explain the bad reaction to the treatment. i dont know if that makes any since . im kinda tired...
