Lucifer (Mark Pellegrino) has some dirty tricks up his sleeves in the upcoming episode of "Supernatural" season 13. Episode 13, titled "Devil's Bargain," will introduce a new faith healer in town who will happen to attract the attention of the devil. Unlike the other mystic healers featured in the past seasons, this person might be possessing an incredible gift that Lucifer himself will be offering her a deal that is too hard to resist. 

"Supernatural" season 13 episode 13 will feature actress Danneel Ackles portraying the role of Sister Jo. The actress happens to be the wife of one of the CW series' lead players, Jensen Ackles. According to the official episode synopsis, Sister Jo is not an ordinary nun as she is capable of restoring one's health. Unfortunately for her, Lucifer has his eyes on Sister Jo's power, and the devil will do anything to persuade the unknowing servant of God to his side. As Sister Jo agrees to Lucifer's term, there will be no turning back for her as the latter could do whatever he pleases with her gift. 

Nevertheless, Sam (Jensen Ackles) and Dean (Jared Padalecki) Winchester will be there to stop Lucifer's evil plan. Interestingly, Sam and Sister Jo's shared scenes on "Supernatural" season 13 episode 13 will be the first time for the real-life couple Jensen and Danneel to appear together on the show. Variety reported that this will not be the first time that the actual wife of a main cast member made an appearance on "Supernatural." Actress Genevieve Padalecki, wife of Jared Padalecki, was also featured in the past seasons as a demon named Ruby. 

Meanwhile, "Supernatural" season 13 episode 13 will also have an update on Asmodeus' (Jeffrey Vincent Parise) search for the son of Lucifer. Jack (Alexander Calvert), the only son of the supreme ruler of Hell, has been missing-in-action for the past few episodes, but Asmodeus will stop at nothing to locate him. The demon wants to invite Jack to join his side so that he could gain more power in Hell, hoping that he could overthrow Lucifer from his throne. Still, Asmodeus cannot be so sure that Jack will follow him.

"Supernatural" season 13 episode 13 will air on Thursday, Feb. 8, 8 p.m. EST.
