The mutiny of the demons in Hell is far from over in "Supernatural" season 13. In episode 14, the fans are likely to witness a showdown between two of the most powerful rulers of Hell, Asmodeus (Jeffrey Vincent Parise) and Lucifer (Mark Pellegrino). The latter was able to outsmart Asmodeus in the previous episode, but in the upcoming episode titled "Good Intentions," the prince of Hell will prepare his secret weapon that is capable of killing Lucifer.

As reported by TVLine, "Supernatural" season 13 episode 14 will feature Asmodeus' plans to take over Hell, and in order for him to do so, he must be able to eradicate Lucifer. With the help of a mysterious faith healer named Sister Jo, who was later on revealed to be an angel named Anael (Danneel Ackles), Lucifer was able to take the throne, forcing Asmodeus to give up the fight for the meantime.

Nevertheless, Asmodeus is still very much capable of reclaiming Hell, especially when he revealed to Ketch (David Haydn-Jones) that he is in possession of a secret weapon that he can use to destroy Lucifer. To recap the previous episode of "Supernatural" season 13, titled "Devil's Bargain," Asmodeus made a surprising revelation that the Archangel Gabriel (Richard Speight Jr.) is actually alive and is now under his custody.

The series has featured many shocking comebacks of dead characters, and Gabriel's return this season does not mean well for Lucifer. Asmodeus is planning to use Gabriel to defeat Lucifer, knowing that only an archangel is capable of killing a fellow archangel. Moreover, the prince of Hell already has the Archangel blade that can pierce through Lucifer's heart, but this weapon can only be used by an archangel.

Aside from Archangel Gabriel, "Supernatural" season 13 episode 14 will welcome another angel, although he is set to bring more harm than good to mankind. Actor Chad Rook revealed on Twitter that he will return to the series as the fallen angel, Zachariah. To note, Rook has already portrayed different characters in the show like Marshall Todd in season 6 and Desmond the vampire in season 8. This time around, he is set to play the role of a mischievous angel that is pushing for the apocalypse.

"Supernatural" season 13 episode 14 will air on Thursday, Feb. 15, at 9 p.m. EST on the CW.
