'Supernatural' Season 11 SPOILERS: Ruth Connell Previews Midseason Finale

Supernatural will air its Season 11 midseason finale on Wednesday, and this will undoubtedly be an important episode for the overall arc of the season. Ruth Connell, who recurs as Rowena on the series, offered a preview of what to expect in a new interview. As always, there are spoilers below.

Rowena vanished off the grid earlier this season after Sam and Dean Winchester (Jared Padalecki and Jensen Ackles) kidnapped her and forced her to remove the curse she placed on Castiel (Misha Collins) that caused the angel to have a severe bloodlust. But she's still clearly a player in the game, so what can we expect from her in the fall finale?

The "Ask Ausiello" column at TVLine has some news.

"Question: Any Supernatural news? -Emmerentia
Ausiello: Although Rowena is still hellbent on getting her mega-coven up and running, her return in Wednesday's fall finale is 'more Winchester-oriented,' her portrayer Ruth Connell previews. Does that mean the witch will finally try to take out Dean and Sam for good? In a word, no. Despite those considerable resources - including 'the Book of the Damned, the Codex [and] the code breaker' - she's 'not going about killing Winchesters,' Connell confirms, adding that new, humanizing details will soon come to light about Rowena's backstory that will help explain 'why she can't' do that deed."

The fall finale is likely to already be packed to the brim, as we know that Sam seeks a way to reenter the cage with Lucifer (Mark Pellegrino) in order to stop Amara aka The Darkness, and he goes to Crowley (Mark Sheppard) for help in doing so. How Crowley's mother, Rowena, is involved in all this is still unclear, but her considerable skills should at least help them in one way or another, assuming she's on board with teaming up with the Winchesters at all.
