"Do you remember what we did last time we had a little get-together?" Ethan said to Claire, smiling as she gasped in terrified breaths. "No?" he asked. She did not reply. "Well then, let me refresh your memory."
He reached into his pocket and pulled out a hypodermic needle, and began to lift the tail of Claire's shirt. Claire screamed bloody murder.
Jack pounced out from behind the tree, tackling Ethan to the ground. Fists flew as the fighters struggled to end up on top, and the hypodermic needle fell to the ground. Jack and Ethan both saw it fall, and Ethan scrambled to grab it, but Jack pulled him back. With a shriek that was more animal than human Ethan scratched Jack across the face with nails that were hideously long, even for a stranded lunatic. Claire continued screaming, hands to her face, tears streaming down her cheeks, huddling away from the wet fight. With one hand, Jack held Ethan's head to the ground.
"Run!" he cried, before Ethan kicked him and the fighting went on. Claire obeyed at once, turning and running for dear life. Ethan looked up from the fight and saw her. A low, almost canine growl escaped his throat, and he grabbed the hypodermic needle from where it had fallen on the ground and stabbed it into Jack's leg. Jack grabbed his leg and screamed in agony as the fluids spread, burning him like millions of white-hot needles in his skin. Ethan scrambled to his feet and began running after Claire.
"Run, Claire!" yelled Jack, still holding his leg in anguish, "RUN!"
Claire ran like never before. It no longer mattered that she was pregnant, or that it was pouring down rain, or that she did not know her way. All that mattered now was that she run and keep on running until she lost her pursuer. She gasped for breath, holding her stomach, and ran.
