I AM JUST GOING TO ASSUME THAT EITHER A) WHAT HE WAS GOING TO TELL US ENDED UP BEING MORE OR LESS WHAT WE FOUND OUT ANYWAY (they were created to protect the 7^3 and/or they were all going to be revived), OR B) AMANO IS HOLDING OUT FOR ANOTHER ARC IN WHICH THE INFORMATION WILL COME UP AGAIN. Because that was obviously a gaping hole in the plot, and yet it never even got mentioned. It would be a huge oversight on her part--too huge.
