I'm not leaving this as concrit on the actual post because it's a personal thing rather than anything that's wrong with the fic.
I was absolutely loving this and all set to rec it until about ten pages from the end when all of a sudden Cas gets called back to Heaven and wipes Sam's mind of ever having met him, after they've been travelling together for two years and are just on the cusp of getting into a proper relationship.
I am disappointed. I just can't bring myself to rec fics that don't end happily.
So unless the fic I am about to start reading is amazingly brilliant I will have nothing to rec from
Disappointing.
