Of Reluctant Allies (The 9+1 Rule For Survival)*SPN x Daredevil*Damned If I Do
4 parts Complete In which Dean and Sam meet the Devil who may care and his little sister who may not be his little sister, everyone has a fake alias and bleeds too much, Claire is not amused and Matt should probably admit that this time, he is actually way over his head. More or less in that order.
Might work a STANDALONE, even though technically it's part of Damned If I Do verse. Set after Damned If I Do, somewhere before Christmas maybe? Before the trial, that's for sure. It's actually not important, you'll see why.
Season 5 for Supernatural - not particularly important either. I don't think profound Supernatural knowledge is required.
