Very well. To be fair, she would very much dislike being told to step aside while others do her job for her, when she is just as well capable on her own.

Mostly.

She slips down onto the tracks, motioning for Firo to stay on the platform and keep going his own way. Her speed and efficiency in her quick step that make her a sufficient killer go to work, as she makes her way around one side of the train. Slipping past four cars of cargo, she finds the two workers at the checkpoint station, conversing. One of them is likely a guard, while the other is the driver of the train. Their shapes are formless, like moving shadows despite the human voices coming from them...

"--head of security's called to get more sentries at the gate."

"How long 'til they get here?"

"'Bout five minutes or so."

Time, as they say, is not on their side. Rather than taking them both out, or relying on Firo to be capable of doing that, she decides on a different idea.

Ripping off the sleeves of her shirt, she squeezes the pieces of rumbled up cloth into one hand. Her fingers clench around the fabrics, until they catch flame.

With that, she tosses them ahead of the train. Fire bursts in front of them and, somehow, starts spreading across the tracks. Suddenly the two staff stop talking and start yelling.

"What the hell?"

"Shit!"

"Put it out!"

They jump from the checkpoint platform and onto the tracks, leaving the train unattended.
