I can't remember the story really but I think it was dean centric. Anyway I saved a some lines I liked, does anyone recognize them?

After all, there really was not much difference between immortality and death
and if one angel could dance on the head of a pin, they all could.

because it had nothing to do with being the cause and everything to
do with being the survivor and Dean knew that as well as Sam did.

But John, John let go of a little of his grief, and maybe, just maybe made a
little more room in his heart and soul for his wife to make her way back in.
Because really, if one angel can dance on the head of a pin, they all can.
Which is to say, that in the Kingdom of Hearts and Souls, all things are
possible.

Help. Please!
