Chp 6: The Legendary King

Present day Underworld, Grace is confronted by King Arthur, who he blames for being defeated by the major power-players. After Arthur knocks Grace out by using his stun gun and draws her blood, as he had made a deal with Hades to help him find Renee. Nyx uses the eye of Fates with the blood, the eye transformed King Arthur into an exact lookalike of Grace. He tricks his grandson Liam and Rumple to lead him to Renee. King Arthur reveals himself when they reach the rendezvous point, after slapping an anti-magic cuff on Rumple, and is joined by Starla/Deathwhisper. When Starla and Arthur enter the harbor, as part of their plan to send Liam and Rumple to their deaths, Zelena and Renee arrive to rescue Liam and Rumple, before it's too late. Renee grabs the gun dropped by Arthur and removed the cuffs from Rumple, and Starla runs back to safety. Meanwhile, the real Grace arrives and attempts to help King Arthur move on while confronting him, as Arthur continues to believe that killing Grace and becoming the powerful believer is the "unfinished business" that is keeping him in the Underworld. After the real Grace's plea to help Arthur falls on deaf ears, the doppelgänger's continue fighting each other on the edge of the dock, with the real Grace wanting the others to stay out of the struggle. As Arthur begins to lose, he pulls out a boot knife, despite Grace's pleas to stop. Grace eventually twists Arthur off into the River of Lost Souls, condemning him to eternal torment, while Starla flees. Liam tells his daughter that there was nothing she could do to save Arthur, despite his best efforts, and that some people just won't ever move on. At the lair, Hades tells Nyx he wants to leave the outsiders in the Underworld forever, then he asks her to be his partner in chaos, Nyx accepts the proposal. Hades also tells her that he took the precaution of adding the remaining outsiders' names to more tombstones, after they got many souls move on. Elsewhere, Zelena saw this through a crystal ball and then confronts the rest of the group  afterwards, Zelena explain this to the rest of the outsiders, saying that Nyx was thinking irrationally and in danger, and telling them that the only way to solve this problem is to go to see the person that knows Hades the most is his niece, to tell them how to defeat Hades.
