Sam and Dean Winchester made a major mistake letting Abaddon back out of her box and it appears they will start paying for it in the second episode of season 9.

The Knight of Hell was in the wind following last spring's "Sacrifice." While the Winchesters brothers (Jared Padalecki and Jensen Ackles) will reportedly spend the first episode tending to their wounds and dealing with the topsy-turvy state of Heaven and Hell, it seems Abaddon (Alaina Huffman) will spend her time working on her plan to overthrow the King of Hell (Mark Sheppard). Not that it should be a particularly difficult task at the moment, considering Crowley is under the control of the Hunter duo.

Titled "Devil May Care," the episode was the first to shoot for the new season and has already wrapped. In describing the plot, director Guy Norman Bee heavily hinted at Abaddon's presence at the start of the season.

"The boys get word of a few of their hunter contemporaries that have been taken hostage by a familiar face from Season 8. He/She leads them to a spot outside Eugene, Oregon so He/She can get info about where Crowley is," Bee told the Examiner. "How He/She is able to take hunters as hostages is a big part of the episode; by the recruiting of demons and getting them to "Be All That They Can Be!"

Will Crowley have to team up with the Winchesters in order to save his crown? Find out when Supernatural returns to the CW on Oct. 8.
