13.18 Bring 'em Back Alive
Meeting Castiel at the playground, Dumah asks if the angels have Jack locked away. She tells Castiel that Jack is not in Heaven, and if he were he would be put to work rather than imprisoned. Confused by what she means, Dumah reveals to Castiel that after the fall, their numbers have greatly diminished and the angels are going extinct as no others have been made since the dawn of creation. The angels plan to use Jack, whether he wants to or not, to make more angels. Castiel argues that Jack is not a slave to be used as a pet. Two other angels appear, revealing that Dumah lured Castiel in a trap to be caught and used by Heaven to get Jack. Dumah asks Castiel to come with them, but Castiel attacks all three, and a fight ensues until Dumah is able to get the advantage and hold Castiel at blade point. However, Lucifer makes his presence known and tells Dumah to drop her blade. Dumah does not comply until Lucifer begins to power up; upon seeing his red eyes, Dumah and the other angels flee back to Heaven.
Dumah and two other angels meet with Lucifer at the playground. Lucifer tells Dumah the angels need him, and in response, Dumah orders the other angels to kill Lucifer. Lucifer stops Dumah, telling her she can't kill him, even in his weakened state. Dumah replies that they can still try, repeatedly, to do so. Lucifer then attempts to appeal by revealing he can create more angels, if he is declared ruler of Heaven, which causes Dumah to laugh. Dumah stops laughing when Lucifer reveals he can also return their wings.
Dumah is later seen in Heaven's Throne Room kneeling before Lucifer with a group of angels.
Entering the throne room in the midst of an argument between Lucifer and Jo, Dumah deflects Lucifer's attempt to draw her into their debate, telling him couples issues aren't her area. When Lucifer asks her about the search for his son, Dumah tells that the few angels they can spare are scanning the planet, but have not found anything, revealing that they do not have the manpower for a wider search. When Lucifer reiterates finding him is a priority, and flashes his red eyes, Dumah agrees and leaves the throne room.
