I put the piece of skin down on the floor, and cocked my gun before firing. "Holy crap!" the bullet deflected right off of the skin, whizzing right past my face.  

"What the heck?!" After we stood there for a few minutes in silence, Jim's spoke up. "It's possible that my pen was special because of one of the plastics in it..."

"What do you mean?" Smith looked on as he took apart the pen, showing particular the plastic tip. "As you might know, this pen is made from a man-made plastic, which contains dioxin, a highly toxic organic pollutant..." He stopped for a second to see if we had anything to say. "It's possible that the dioxins in the pen tip were what killed the newborn Europan. So what we need to is go to the 3D printer on the other side of the ship and print out some weapons containing the same plastic as this pen. Until then, even if we were to find the mother we would be helpless against it."

Smith and I both nodded in agreement.

"Sounds like a pretty damn good idea."
