She's dangerous, Weiss thought. She was able to defeat Yang so easily, and she's probably the strongest out of all of us. Their chances against this girl were all the worse for the battlefield they fought on. Normally, they could have used teamwork to wear their enemy down, but out here, all it would take was to lose your footing for a moment and you'd be dead. This girl didn't need to beat them. She just needed to knock them off the train.

Qrow seemed to realise that, for he flung an arm out before them. "Get Yang up and go downstairs," he said, never once taking his eyes from the girl. "You'll need to make the rest of the way below. I'll keep her busy while you get to the front and shut this down."

The train continued to rattle and howl as it travelled through the tunnel, but if the girl ahead heard Qrow's words, she appeared remarkably unconcerned with them. Blake helped Yang to her feet, while Weiss backed away to the last carriage they'd crossed.

The last thing they saw as they descended, was the huntsman's weapon crack apart and begin to extend. Any more was cut off as they forced the door open and pushed inside, but the sudden clash of steel above told more than enough.

Above them, a gunshot sounded, a reminder that the fight between Qrow and the mysterious girl was still in full swing.

"It's just one person…"

"Who could fight your uncle on equal grounds, Yang. We can't be stupid here."
