Complete story — includes the ending
After weeks of searching, Kaldur's party finds Arion's crown and returns it to Poseidonis. M'gann discovered from her telepathy that both Orm and Arion are clone created by Vandal Savage for his plan to taking control Atlantis. Using Orm as a distraction, Arion is loyal to the Light and followed Savage's instruction. As Arion puts the Crown on, the Lords of Order disintegrate him, deeming him unworthy and removing the Crown's magic. Arthur refuses to be the High King again, and Mera becomes regent, fulfilling the prophecy. Arthur decides to focus on being a father and returns to the League. La'gaan agrees to be Aquaman too and Kaldur decides to take a leave of absence from the League. Meanwhile, Doctor Fate goads Savage for his failure in taking over Atlantis. In a mid-credits scene, Kaldur seeks counseling with Black Canary, confronting his grief.
