Season 4 Episode 1: Introduction
His throat felt like a twig beneath the palm of my hand. Cassidy was so fragile... so small. Yet he was the reason behind the chaos consuming my life. His pulse pounded against my skin as I squeezed tighter, feeling it grow slower as I held him suspended against the wall. I could have done it. I could have ended him right then and there, but then he spoke. If what he said about Grace Kingsley being my mother was true, I longed to know more.
Kyle gripped Cassidy's throat even tighter than before when he claimed to be his brother. What kind of person would threaten to hurt his brother and everyone he cared most about? Why did he deserve to live? Kyle panted, his nostrils flaring as he looked Cassidy straight in the eye. He would soon pass out if Kyle didn't let go now, but Kyle hesitated. He was so angry of the words he spoke about making Jessi wish she were dead, and hurting everyone he loved starting with Amanda.
Then he thought of the Trager's. He remembered the look on Stephen and Nicole's faces when Cassidy told them how Jessi had murdered that man in the woods. They were shocked, terrified, and disappointed. Kyle then placed himself in Jessi's shoes, and imagined if his family looked at him the way they looked at Jessi; a murderer. His grip around Cassidy's throat loosened, and the man fell hard onto the ground, doubling over and gasping for air before choking on his own cough. Kyle stumbled backwards, tripping over a piece of the broken doorframe and also falling onto the ground. His head spun as he had a brief moment of panic. He had been so close to taking another man's life. What had he become?
