Changes

Dean tells [[Sam]] about what happened to him in [[4.03 In the Beginning]], including his encounter with Mary. Sam is amazed to find out that she had been a hunter and asks Dean to tell him what she was like, leading Dean to describe her as an awesome, funny, smart and hopeful person. Sam wonders what the point was to Azazel killing her and the rest of their family, just to give him demon blood.
