Cas didn't understand what Cullen said but it didn't matter the searing pain f the sword cutting through his body took his mind off of what Cullen said. He yelled out feeling then final blow. everything around him began to blurr, he could hear Shirnday and then he couldn't "no" he was more worried about her than he was about himself and even more about Cullen, he had just crossed a line that would forever change his life. He tried t move but the sword had him pinned t the ground and the slightest budge sent waves of pain through him.
Thomas was shocked by what he had just witnessed, his son had murdered his own uncle someone he was sure Cullen looked up to, he knew it wouldn't belong until Cas would take his last breath he could feel part of himself dieing and knew what it was. He walked over to Cas with his head hung, he gripped the handle and with one swift tug pulled it from his chest. Cas yelled out but settled feeling the pressure subside "he can't,,be,,, helped" Cas said looking up at Thomas.
