KF:TLC post-series (fic) thoughts

I was thinking about post-series and things I'd like to see.

Obviously, Paul's return would be a cool thing. I've read several variations on this. I feel like thematically, he needs to return of his own volition once he's defeated his inner demons. But that doesn't make as exciting a story as his life in danger, I know. I do think it needs to be a little bit - not happen right on the heels of Peter leaving the force.

In-universe explanation for who is Peter’s partner when?

Does Peter even have an official partner?  Do any of the cops on this show?  Is there any consistency to when Skalany is his partner v. when Jody is?

Partner-fic with Peter and Jody or Mary Margaret?

Can anyone recommend me some good “partner-fic” with Peter and Jody or Mary Margaret as his partner?  A case-fic, I mean.  Multi-chaptered, and with a bad guy to take down.  But with a lot of emotional interplay and friendship.  Can have supernatural weirdness or be a normal human baddie.  Set any season.
