I'm looking for a fic called "but thank the stars we are entwined". In the fic Sam makes Dean tattoo himself with different protective symbols and Dean thinks Sam being a little paranoid and is a little annoyed that all the symbols are in the shape of a circle. At some point Sam gets a tattoo across his shoulders in Latin that translates to "If I cannot move Heaven, I will raise Hell".

I had this fic bookmarked and it's one of my all time favourites but when I tried to read it today, I realized to my horror that the entry has been deleted. So if anyone knows of any other place where I can find this I would be eternally grateful.

FOUND! Thank you. :)
