It had been nearly a week since Uriel's betrayal and the shock was still fresh in Castiel's mind. His world was disintegrating into nothingness and he was helpless to stop it. He felt so insecure and vulnerable. "How could Uriel kill our brothers and sisters? How could our Father allow His angels to murder one another and do nothing about it?" Castiel asked himself. These were questions he could not answer, but he knew one thing was certain. His thoughts could not be spent dwelling on the past; he had to help Dean protect the future.
