CNYK - Cinder/Qrow

The moment she regained consciousness after the Fall of Beacon she knew he had betrayed her. And not just because Qrow was absent from within the long winding halls of Salem's hideout.

She had expected it, but she thought it would be more fulfilling. Even if they had been playing with each other Cinder was sure she had been the cat, not the mouse. That she had tricked him and led him astray for one second too long that he would blame himself entirely for what happened at Beacon, and every Academy that followed its example. She hadn't expected to be the one suffering in the end.

Her body writhing in pain, but unable to express it as she could only hiss. The panic that had overcome her upon realizing her voice was gone. That she couldn't see out of her one eye because it was no longer there. Just a scar of human tissue remained, red and angry.

It was his fault. He had remained too close to her without anything happening all that time, and then it hit her fast and hard. His semblance that she had thought so amusing. It would keep him forever from finding any real happiness. He brought pain and destruction everywhere he went. That's what had intrigued her. A wandering tortured soul trying to stay on the path of light even with the curse that had been bestowed upon him.

That's what destroyed her.
