Things aren't looking very good for the Winchester boys during season 11 of Supernatural.

Not only did Sam (Jared Padalecki) and Dean (Jensen Ackles) release the Darkness into the world, but that Darkness infected one of them. To add to that, there's an evil child out there, Crowley (Mark Sheppard) showed up in the most recent episode dressed as a priest, Castiel (Misha Collins) is having a tough time of dealing with things and this season has already packed a powerful punch with just a few episodes.

So, what's in store for next week? A new preview released by The CW of the upcoming episode, "The Bad Seed," shows even more trouble with Amara, as well as the return of one of the biggest thorns in the boys' side, Rowena (Ruth Connell).

It's unclear as to whether the bad seed in the episode's title refers to Amara (and offers a bit of nostalgia for the old horror film of the same name) or Rowena, as both are bound to cause trouble for Sam and Dean.

It's also likely that Sam isn't really cured from the Darkness, because let's face it, that cure in the last episode was a little too easy. Anyone who has watched the series from the beginning knows that nothing ever comes that easy for the Winchester brothers.

Here's the official synopsis for "The Bad Seed," directed by Ackles:

"While Rowena (guest star Ruth Connell) tries to consolidate her power to protect herself from the Winchesters, Sam (Jared Padalecki) and Dean (Jensen Ackles) search for a missing baby connected to the Darkness. Meanwhile, Castiel (Misha Collins) struggles to heal and Crowley (Mark Sheppard) tries to find a way to use the Darkness for his own personal gain."

As we now know, that baby is Amara, who has grown into a young girl, as seen in this new preview. It's likely she'll continue to grow until she becomes a young adult, perhaps becoming the personification of the Darkness itself: will she grow up to become the woman (Emily Swallow) that Dean sees in his visions?

"The Darkness is really a monolithic bad guy for us," said Supernatural co-executive producer Andrew Dabb to The Hollywood Reporter. "She will have a particularly strong point of view that will come through and it's something that we can grow and develop over time into a fully-realized character. This person is going to be really scary, intimidating and wry like some of our best villains have been."

"The Bad Seed" episode of Supernatural airs on The CW on Wednesday, Oct. 21.
