Ruby looked down at the hands that had killed the rest of team RWBY- her hands. She wondered vaguely if the blood would ever wash off of them.
As the sun fell, the battle field was in ruins. Weiss, once colored white with the barest accents of red, was bloodstained to a point where even if the dress she wore had a reason to be fixed, it couldn't be. Blake lay to Ruby's right, her eyes still open in disbelief. As if even in death, the faunus could not imagine that the little girl who believed that they could make fairytales a reality could go so bad. Behind the young murderess was a fire feasting on the body of Yang and releasing a toxic stench from the body of Penny. Yang's semblance had finally taken the older sister's life as she protected her misguided sister from a robot just following orders- to kill the first friend she'd made.
Ruby now stood there, Crescent Rose abandoned at her feet, hands now crusted with blood instead of dripping with it, wondering what she had done. Hearing footsteps, she looked up.
"Did- did they really have to die?"
"I'm sorry, but- yes. They were only a fairytale, a weakness. The lie they represented has died with them. And- our plan couldn't move forward with them alive."
It was the only person who could convince Ruby that killing was necessary, who could take away the child's guilt: Cinder. As the manipulator's lover picked up her scythe, bloody hands decisively ignored, she focused on one thing: pleasing her queen.
