Season 3 Cast Timeline: from Battle of the Gullet Chaos to the Premiere Aftermath
While Dragonstone grapples with maritime warfare, the Red Keep decays from within. Olivia Cooke’s Alicent Hightower spent the close of Season 2 realizing her influence over her sons had completely collapsed. Stripped of her small council seat and alienated by Prince Regent Aemond, Alicent made a desperate, covert plea to Rhaenyra to surrender the city in exchange for lives.
That bargain quickly disintegrates under the reality of wartime chaos. Ewan Mitchell plays Aemond Targaryen with escalating tyranny, driving the capital toward financial and civic starvation while taking Vhagar into the Riverlands to scorch settlements. His absence leaves the Red Keep defenseless against direct airborne invasion. Tom Glynn-Carney’s Aegon II, severely crippled and spirited away in secret by Larys Strong (Matthew Needham), leaves a leadership vacuum that ensures King's Landing falls with minimal military resistance.
The physical seizure of the Iron Throne by Rhaenyra creates an entirely new acting dynamic between Cooke and D'Arcy. Once friends, then bitter political adversaries, their upcoming interactions strip away courtly pleasantries. Cooke must portray a disgraced matriarch who realizes her family’s pursuit of power yielded nothing but ruin, while D'Arcy portrays a ruler whose victory brings immediate administrative paralysis and urban revolt.
