Y/N had met Sam and Dean Winchester about 3 years ago on a shapeshifter hunt. She helped sam and Dean track it and kill it with silver. While the time you were with the brothers, you and Dean argued, constantly. While Sam was more civil. Atee the hot ended Santiago you his number just incase behind deans back. You were in Kansas finishing a hunt when you got shot and were actively bleeding out. You got in ur car and called Sam. You needed help and this was a last resort.
