I don’t see that her being cyborg is relevant.

Did you know that she was cyborg?” asked a woman in an unhidden tone of disgust.
Kai stared at her, appearing confused, then let his gaze dance over the crowd. He shuffled his feet
closer to the podium, a wrinkle forming on the bridge of his nose.
Cinder bit the inside of her cheek and braced herself for adamant disgust. Who would ever invite a
cyborg to the ball?
But instead, Kai said simply, “I don’t see that her being cyborg is relevant. Next question?”
Cinder’s metal fingers jolted.

WINTER SPOILER - KINDA IDRK
Cinder looked away. Though so much had changed between them since that night, it still felt like an ice pick in her heart when she remembered the way he'd looked at her, and his horrified words: You're even more painful to look at than she is.

What do you mean? Is she in a coma?”
“Not anymore.” She braced herself for his reaction.
“But she’s a cyborg.”
His eyes widened, but then his attention was darting around the room as though he couldn’t look at Cinder while he adjusted to that information. “I see,” he said slowly, before meeting her gaze again.
“But … is she all right?”
The question caught her by surprise and she couldn’t help a startled laugh. “Oh, yeah, she’s great. I mean, half the people in the world want to kill her and the other half want to chain her to a throne on the moon, which is just what she’s always wanted. So she’s fantastic.

I am not human.
I am a cyborg.
I am mechanic.
That's all I am... right?

Come on, Iko.”
Iko was still hiding, hugging herself self-consciously. “Is he looking?”
Kai raised an eyebrow.
“He’s not looking,” said Cinder.
A hesitation. “Are you sure?”
Cinder gestured exasperatedly at Kai. “You’re not looking.”
He cast his eyes to the ceiling. “Oh, for all the stars." Crossing his arms, he turned his back on them.
