GUhhhhhhhhhhhhhhhhhhhhhhhhh This is such a beautiful imagining of it. I love this. I love Jimmy's empathy and the explanation for his choice that this provides. but when he did he was ready Fantastic! It just makes me even sadder that it all goes so wrong for Jimmy and his family, that this calling costs him so much.
But this fic is so gorgeous and so necessary - you filled a gap in canon with utter perfection.
Guh: little Sam and Dean, especially Dean being all vulnerable and ballsy at the same time. And just the thought that this fic exploits of them all being manipulated by greater powers from so early on. Damn girl this'll linger in the mind I think!
