The real Silver may actually be human. He may have a connection with Ur in contrast to being a Devil Slayer (maybe he got angry because Deliora was the reason Ur sacrificed her life and thus vowed to be a Devil Slayer). This may also be the reason that he was so angry at Gray, because he knew that Ur sacrificed her life for the young Gray, and vowed vengeance against him one day.

About the Erza and Minerva confronting Kyouka part, I think it's a bit predictable. Kyouka is nowhere to be found and the Chairman can be stopped easily by Erza.
