Dean/Castiel in Hell - Specific fic

[furyseed.livejournal.com]

Hello again,
friends!
I was searching for this fic I read a while ago and tried to look at all the related tags but still haven't found anything, so I hoped you could help.
So, basically, Castiel goes to the rescue during Dean's time in hell, he tries to convince Dean to follow him but Dean is Alastair's pupil and he's unfortunately used to tortures now, he's also convinced he's too damaged to be worth something.
It's a very graphic story, wherein Castiel stays in hell ('til he manages to earn Dean's trust), Dean tortures Castiel (there's also non-con if I remember correctly) but all through the fic Cas never loses his hope that Dean will remember he's not evil and he never loses faith in him and his soul.
I hope someone knows what I'm talking about, I don't remember much else.
Thank you in advance :-)
