The new episode of "Supernatural" season 11 airing tonight will see Crowley take advantage of the Darkness. The King of Hell has successfully lured Amara, whose huge appetite for souls he may have failed to prepare for.

In the previous installment, Amara was just a baby but after a few hours, she grew into a pre-teen. Fans may have already heard that an adult Amara will be played by Emily Swallow, so expect the Darkness-laden youngster to rapidly mature.

The promo for the upcoming "Supernatural" season 11 episode, which is titled "The Bad Seed," sees Amara "pig out." In the trailer, she tells Crowley she is hungry and it looks like Crowley happily provided her something to munch on as seen in the clip.

While all this takes place, Sam and Dean search for Amara. However, they will be busy trying to nab Rowena as well, which won't be an easy task, apparently. The sneak peek teases that Rowena, whose spell on Castiel remains in effect, is doing her best to protect herself from the brothers.

At one point in the clip, she is seen freaking out and screaming. Toward the end of the promo, she is spotted masquerading as a blonde woman to hide her incriminating red locks and ultimately avoid attention. Unfortunately, at some point, her cover will be blown.

More than all the chaos happening in the "Supernatural" season 11 episode, the Winchesters also need to keep an eye on Castiel, who can snap at any time. But if the duo finally catches Rowena, who has the answer to Castiel's liberation from the spell, Amara will be the only one to worry about.

Darkness, however, is still a bit too huge to fend off but at least a recovered Castiel can contribute in repulsing it.

 "Supernatural" season 11 episode 3 "The Bad Seed" was directed by Jensen Ackles aka Dean and airs Oct. 21 at 9 p.m. ET on The CW.
