Me loves Miko. Nevertheless, this is my prediction:
She is in shock. Hinjo will have her arrested and thrown into prison. She'll be in despair in the prison, asking herself how she could have been so wrong. There she'll meet Nale and Sabine, who will begin to work their poison into her heart. They'll slowly convince her that she was not wrong, but that the whole world, and even the gods, have turned against her. She'll come to believe that everything she ever believed in was a lie, and she'll look for a new philosophy on which to hang her trust. She needs to make sense of the world again, and Nale and Sabine will help her fill that void with lies.
Thus, she'll become a blackguard. But the transition will take time. Likely Xykon's attack on the city will destroy the jail and set them free. Free to regroup and renew their evil plans. Of course, Sabine and Nale are both interested in these gates. (What gates?) And so they'll try to do something with them or about them. I have no idea what, though. But doesn't Miko know about the secret of the gates? Maybe she'll tell them what she knows, since she may feel as though her past oaths no longer have any meaning.
I can't wait to see what will happen next!
