This is when I KNEW this scene was going to kill me. When Cas, UNPROMPTED, started talking to Dean ABOUT JOHN. Because mentioning John to Dean is like waving a red flag to a metaphorical emotional bull. It GUARANTEES AN EMOTIONAL MOMENT.
Oh man, and now I’m having THOUGHTS. Because John’s journal is the written word of Dean’s father. It’s Dean’s bible, basically. So Cas is looking at it, and admiring it, and he’s saying ‘your father had beautiful handwriting.’ He left a beautiful legacy for you. My father? Not so much… And he’s trying to be a hunter right now, and this is a hunter’s bible. So he’s thinking, maybe, I wish the written word of my father was this beautiful. I wish this was my bible. I wish my life was your life, Dean.
And now I want to cry.
