"OKAY. NOW YOU CAN FUCK OFF." The man screamed out in pain, grabbing the mechanical cop's arm and pushing it back, dropping himself to his knees. He did a roll, lunging for the sword. He grabbed it, spinning around to re-face the robot.  "You....have really pissed me off, you sorry sack of metallic shit! Even as a machine, cops are still just pigs, I guess." He said, taking out another vial and slamming it it into the sword's rather large guard. It was incredibly big, and looked more like a block of metal than a proper hand guard, a tell-tale sign of the type of the sword it was. A machine sword, a weapon made for use with magical vials. 

A second vial popped out as the first one pushed into the sword, this one used up. "And if you're a pig, I'll take ya to the damn slaughterhouse!" He slammed the bottom of the sword's handle, the blade bursting into flames. He pointed the weapon forward, muttering under his breath. "Girl." He said suddenly, looking at Mandy, his face plastered with a looking of amusement. "Get ready." He instructed, a magical circle made of light suddenly appearing around the blade. It was impossibly complex, filled with runes and designs only the most masterful of magic users could understand.

"Detonator Shot" He said, his eyes suddenly back to the machine, letting go of the sword's handle as it shot forward, flying like a bullet though the air, the heat of the blade distorting the air and catching fire to the green leather seats of the train, filling the air with black smoke and a smell to match.

What it did to the machine, however, the man did not know, as he suddenly rushed over towards Mandy. In a single fluid motion, he grabbed onto her, gripped onto the window, and threw  himself and the girl out, using momentum to flip themselves on top of the train. He broke into a run, still carrying her, jumping to the next train car. "Okay, okay, okay. This will get us a few seconds, at most." He said, putting her down, taking out a second dagger and giving it to her. "Here. There's an exit hatch on this car. Use this to force it up, and get to safety."
