In disc 3, I went back to Midgar and the guy just to the left of the pipe says
"There were these men chanting, about some sort of Reunion."
Could these "men" be Kadaj,Yazoo,and Loz. They are the ones in AC who work for Sephiroth to get him and Jenova back together. Post your ideas:-)

No.

I believe these men were just simply all the Sephiroth Clones.

This is a theory and technically belongs in the Ac thread.

I highly doubt that they are the same.
