A year after Sam went to Stanford, when you were twelve, you died in, Dean's, your big brother's arms. John and Dean burned your bones and thought that was the end of it. But Dean had kept your favorite necklace. That's what your spirit attached itself to.

Dean learned this pretty quickly. He kept it secret from John, carried your necklace everywhere, and refused to burn it. You liked to just appear to talk to Dean. Like now, when he was driving the Impala down to Louisiana to hunt something, he wasn't sure yet.

Dean jumped when you greeted him. "Never getting used to you just popping up," He said, shaking his head.
