"Jayne’s downcast eyes held no emotion, although he was tearing apart inside. He would never be a true part of the crew; he was used to being left out, although it still deeply hurt all the same. In time he had learned to revel in the revulsion that was always sent his way, whether it be a look, word, or action. The pain would always stay in his thoughts, circling like a brooding dark cloud ready to release its bitter tears. But through this pain he gained strength. A strength to keep his emotions numb, and thrust his acidic thoughts elsewhere."
