RETURNS Summer, HBO
Civil war is coming. In the sophomore season of this fantasy drama, Rhaenyra Targaryen (Emma D’Arcy), who considers herself the rightful ruler of Westeros, faces off against her half brother, newly crowned Aegon II (Tom Glynn-Carney). Her patience for peacekeeping was cruelly cut short in the Season 1 finale due to the loss of her gentle 14-year-old son, Lucerys (Elliot Grihault), while on a diplomatic mission: As he and his dragon were flying away from Storm’s End, the king’s brother, Prince Aemond (Ewan Mitchell), lost control of his massive fire-breathing mount, who ended up gobbling down the young royal.
