Putting this behind the cut just in case it's still spoiler.

So I was wondering, are there any fics already out there focused on Dean's new Mark of Cain? I tried to look myself, but most that I found at AO3 were Destiel and focused more how Cas reacts to the Mark etc. I'm not Destiel shipper so it wasn't something I was really interested in to read. What I'm looking for are fics that explore the meaning of mark for Dean, maybe focus about what possible new abililiteies he has thanks to the mark, how it changed him, how darker he's becoming etc. And also how Sam reacts to it, how he maybe trues tomsave his brother. Cas can be in a fics too, but I'd rather for it to not be a Destiel fic. I don't mind Wincest or gen.

Also other fics I'd be interested in are how Dean is dealing with all guilt, Kevin's death, Sam not trusting him and being left alone in the world. Maybe how easy he can manipulated now by Crowley or Abaddon? So any fix post 9x11 that focuses on Dean would be great.

Any length of fics is good. The longer the better. WIPs are ok and so are self-recs :) I tried to tag this post as best as I could but the episodes I'm asking don't have tags yet.
Thanks in advance!
