After the last episode of "Supernatural" caught fans up with the storyline for the season, it is now time to go back and visit an old friend with another case of the week. But the Darkness will still be around for the show.

Episode 7, titled "Plush," will air on broadcast network the CW next Wednesday, Nov. 18 at 9 p.m. EST, according to TV Guide.

The season theme of the Darkness will be taking a backseat again with the next episode as the Winchesters are called away to take on another case of the week, according to Spoilers Guide.

But this episode will feature the return of Sheriff Donna (Briana Buckmaster) from last season's Sheriff's Retreat episode. Donna is still fresh to the whole monster thing and she encounters some issues that are a little above her pay grade, and expertise.

She calls Dean and Sam Winchester in to help her get a handle on the situation, which involves a terrifying murder that appears to have their specialty written all over it. There will also be supernatural elements in her town that she does not know how to deal with and she brings them in to help her get ahead of the situation.

Also, Sam will continue having disturbing visions that started in the last episode. It appeared to be someone trapped in the same box that he was once trapped in, the box that holds Lucifer and Michael.

This leads Sam to further ask God for help, much to Dean's dismay. That's because Dean found out the bombshell news in the last episode that Amara (The Darkness) was actually God's sister, whom He locked away with the Mark of Cain in order to create his world with people and society. Of course this is something that he could understand from Amara and he eventually let her go, later lying to Sam and Castiel about it.
