Man all these posts about Cinder's arm is scaring me. I used to think the best argument for redemption for her was the point that Cinder needed to be proven wrong about power and that it isn't everything or what she needs. I guess it eating her alive would prove that too...
Now I guess it's all just a waiting game to see when the power consumes her and she just becomes a full on monster. This was my worst fear of being invested in her character to be honest.
