In episode 19 (yet to be aired), Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) will tackle The Chitters, monsters that appear every 27 years in a town of Colorado. These monsters are responsible for mysterious disappearance of the people of the town. During their investigation, they meet a pair of hunters.

Moving on "Supernatural" Season 11 episode 20. According to the Spoiler Guide's description for "Don't Call Me Shurley," Amara (Emily Swallows) or Darkness will return and continues to wreak havoc on people. This time, she targets a small town. She immerses the town in a mysterious dark fog that causes its people lose their mind.

Upon investigation, Sam and Dean figure that it could be a form of "a strong version of the original black vein virus Amara previously unleashed." In order to prevent the town from the sickness, the Winchester brothers collaborate with the sheriff of the town. However, they may not succeed in their endeavour as the virus is stronger and the remedy is not effective anymore.

Meanwhile, fans must prepare themselves for the return of Rob Benedict's Chuck, who is believed to be a Prophet of the Lord or God himself, at last will be appearing when Darkness gets out of control. He will be here with "an interesting proposal." Who this proposal is for remains to be seen.

The news about Chuck's return was first reported in February 2016 by TV Line. And he was last seen in the 200th instalment of the series. Previously, Season 11 saw the return of Jim Beaver and Steven Williams as Sam and Dean's hunter friends.
