Episode: 2
Episode 2 recap: The Decree Changed
King Aldwin confirms Seraphina's intention to wed the Dragon King. Remembering the war from her past life, Seraphina willingly trades places with Isolde to protect the kingdom. The King orders the marriage decree updated immediately. Cassian arrives from the battlefield wounded and covered in blood, dropping to his knees to plead that Isolde be spared from the dragon realm. Seraphina asks if he cares that she must go in Isolde's place. Cassian dismisses the treaty as cowardice and declares he would rather die in battle, indifferent to Seraphina's fate.
