I'm pretty sure this story was deleted unfortunately but I'd love to be wrong! It was a one shot (or at most two chapters) and set in s12, either replacing or following the events of Rock Never Dies. Lucifer was able to hurt and assault Sam but the story is more about Vince in the post-possession haze realizing what happened and it was angsty but a great dynamic between two of Lucifers discarded vessels. 

And as for a general request, any stories where John is either brought back to life or through like time travel is able to see Sam (preferably set after s5) and see how messed up life has become for his son. "And Beats High Mountain Down" and "The Right Call" kind of stories. 

Thank you for any help/recs!
