sEason 6 au with dean & Cas

[semaniac99.livejournal.com]

been rewatching season 6 with a friend and now I really want a fix it where dean did end up helping cas somehow during it

I do not mind if cas went to dean at the beginning or later or if dean intervened or learned of it somehow and got involved and changed things

would prefer it was only dean but if you know one where everyone got involved too I'd like to see it too.

longer than between a rock and a hard place would be preferred. I have already read the vampire dean chronicles

no sam/male pairing other than Lucifer please, even minor references in the background
