Gawd, I LOVE this. Dean's quiet aching, and how he always knew Sam would leave.

This line?
There's a moment when Dean wants to tell Sam about the journal. Wants to say, it's always been you, little brother. If I wrote my story, it would be pages and pages of you.
I think I stopped breathing because this REALLY hurt. *sigh*

As always, so lovely, Carmen. ;)
