Their Brother, the Dragon SacrificeEpisode 3

Alistair, an abused foster son, volunteers as the kingdom's dragon sacrifice to escape the family that raised him. Stepbrother Dorian frames him again and again, and the family believes every lie. Expecting death, Alistair instead finds dragons kneeling before him: he is their lost prince. Reborn as Dragon King, he returns to claim two crowns, only to meet the family that scorned him with cold silence. As they beg forgiveness, Alistair chooses distance, rising beside dragon leader Sule.
