Pretty much what it says in the title c;
Thanks in advance to anyone who can find this fic for me! :)

other info:

> cas was tortured by leviathans that made themselves look like dean

> cas thought dean was a leviathan when he first saw him

> he threatened him with a knife until dean convinced him that he was himself

> dean got into the building easy because every leviathan thought he was just disguised as dean to torture cas

> i think dean hasn't told bobby or sam that he went to kill roman

And that's all i know sorry ^_^
