Well we're still in the final throes of hellatus.
If we can't have any new episodes... why not INVENT them? We've done posts & articles on pitching spin-offs but none yet (or they're way buried in the archives) of a regular part of the show.
So readers! We're the SPN writers room. Toss out your ideas labeling "arc-" for an entry meant to run an entire season and "epi-" for an entry meant to run just one episode.
And everyone else can comment.
Some of mine:
epi- The ghost of a woman ends up possessing the Impala and asks the boys to solve what happened through the radio. Dean struggles with his car finally being able to love him back, but turns out she likes Sam! Possible titles: "Lovers in the Night Rider" "2 out of 3 ain't bad"
epi- While drifting through town, Sam & Dean decide to stop at a carnival. Things go wrong on some rides, leading them to investigate the rumors of gremlins. Then it gets personal when they start taking apart Baby... Possible titles: "Tore Up Over You" "Gremlins 3: This time it's personal"
arc- Sam & Dean work on rebuilding the Men of Letters, spending a year meeting colorful characters and recruiting them. They know they've succeeded when, at the end, they're kicked out of the bunker.
Multiple entries allowed (just make a new reply to this one, leave comments open for people to comment on your ideas), have fun everyone!
