Everyone is looking for Rowena. The Winchesters want to find her to lift the spell she cast on Castiel, as well as wrestle the Book Of The Damned from her grasp, while Crowley wants to settle a score with his mother... after she tried to have him killed.
For her protection, Rowena is trying to persuade fellow witches, from the Grand Coven, to join her in a "Mega Coven" but with little success.
Meanwhile, Crowley has whisked young Amara (Gracyn Shinyei) away to his castle in Hell, where - between soul food snacks - they discuss the flaws in God's plan for humanity as she decides how she will reshape the world to her own ends.
It's these conversations, in particular, that make The Bad Seed such a fascinating episode, as the role of God in the Supernatural-verse has never been so overtly discussed, debated, or challenged.
Since angels were thrown into the show's mix, he's always been a background presence, but his direct involvement in the imprisonment of The Darkness and now the hints at Amara's plans suggest a direct confrontation is on the cards.
Even the return of Rowena to the fold can't diminish the darker tone of this season (I have no issue with the levity she brings, as humour has always been a key element of Supernatural's winning formula, I just don't think she's a particularly interesting - or well portrayed - character).
Hopefully, although her story arc is clearly unfinished, she won't be returning too soon.
