Dean sat next to Cas. They were sitting in the Impala in front of the place Cas worked.

"Why did you save me so many times?" Dean asked. That question had been bothering him for so long. He had to ask. He knew there was something more than Castiel told him. There had to be.

"The reason? Your mother asked me to," Cas said. Dean was surprised. He hadn't been expecting that.

"When you were about a year old, your mother had a terrible nightmare. It was kind of like Sam's visions. She saw you in hell. She woke up terrified for you. She prayed for five hours straight that God would send an angel to protect you and keep you out of hell. When John woke up, she told him about the nightmare. He dismissed it as ridiculous. But when your mother was killed and he learned about all of the supernatural beings, he feared for your life. That's why he was so cautious and demanding when you were growing up. He wanted to keep you out of hell because of your mother's nightmare. From the moment your mother prayed an angel would protect you, I did so. Why do you think she told you that angels were watching over you when you were young? She believed that there was an angel taking care of you. And I was. She was right. When you went to hell, I knew I was supposed to rescue you. I knew that Mary's dream had prepared me for this. So I rescued you. And every time you needed rescuing after that, all I could hear in my mind was Mary's voice that night when you were only a year old, begging me to take care of you. Begging me to keep you safe. There were sobs mixed in as well. So I took care of you. Like she had begged me to do when you were young. I rescued you," Castiel explained. They sat in silence for a long time. Dean's eyes were shiny with tears. Because of his mother so long ago, he had a best friend. One that cared. He smiled. There was a plan for him after all.
