s father's words. But they are as empty on his lips as they feel in my ears. This was has taken everything from him. I see in his eyes how broken he is. how terribly hard he is trying to be his father's son. If he could, he would choose to be back by the campfire we made in the highlands of the Institute. He would return to the days of glory when life was simple, when friends seemed true. But wishing for the past doesn't clean the blood from either of our hands.
