Ser Criston Cole House of the Dragon season 3 begins with the Lord Commander of the Kingsguard in a position that should feel like the apex of his power — and that is exactly why it is the most dangerous place he has ever been.
Fabien Frankel has played Criston Cole since the first episode of House of the Dragon — the knight from the Dornish Marches who became Rhaenyra’s personal protector, then her rejected lover, then the instrument of her father’s court against her, and finally the military architect of the Green faction’s war. By the end of season 2, Ser Criston Cole is Lord Commander of the Kingsguard, the Green faction’s most effective battlefield commander, and the man most responsible for making the war prosecutable on Aegon II’s behalf.
He is also a man whose choices have been accumulating behind him for three seasons. Ser Criston Cole House of the Dragon season 3 is where the bill arrives.
In a June 9 interview with Extra, Fabien Frankel and Olivia Cooke discussed what lies ahead for Criston and Alicent in season 3 — confirming the season tests both characters at the limits of their respective loyalties.
Who Ser Criston Cole Is in House of the Dragon Season 3
The Ser Criston Cole House of the Dragon season 3 character occupies a specific and increasingly complicated position in the war’s strategic picture.
Cole is the man who killed Joffrey Lonmouth at Rhaenyra’s wedding — in public, without royal command — because Joffrey threatened to expose the relationship between Cole and Rhaenyra that had already ended. He is the man who championed Aegon II’s coronation before the king’s own faction had committed to it, acting on Alicent’s behalf with a decisiveness that was either loyalty or ambition, depending on how generously you read it. He is the man who executed Vaemond Velaryon’s body when it was already dead, because desecrating a corpse felt like the right expression of his contempt.
Ser Criston Cole House of the Dragon season 3 is therefore not a sympathetic character who made difficult choices. He is a character whose choices have been consistently self-interested, framed as loyalty, and carried out with a precision that makes him genuinely frightening. The Lord Commander of the Kingsguard has authority over the king’s protection and discretion over the king’s enemies. In a king’s court that no longer has a functioning king, that authority becomes something closer to absolute.
His season 3 configuration — loyal to Alicent personally, serving Aegon II nominally, operating in a Green faction that is losing the war — is the specific trap his career has been building toward. He has made himself indispensable to people who are running out of power. The question season 3 asks is what a man like Criston Cole does when the machinery he has served collapses.
Ser Criston Cole House of the Dragon season 3 is the show’s most precisely observed study in the specific corruption of loyalty used as moral cover for self-interest — a knight who has spent three seasons telling himself he is serving his queen, who is about to discover what serving her actually costs when her cause is losing.
Ser Criston Cole House of the Dragon Season 3 and the Military Campaign
The Ser Criston Cole House of the Dragon season 3 military role is the character’s most active configuration since the show began — because the Lord Commander is now fighting the war in the field rather than managing it at court.
The Green faction’s campaign in season 3 involves Criston Cole leading conventional ground forces in coordination with Aemond (commanding Vhagar) and the broader Green military effort under Ormund Hightower in the south. Cole’s specific battlefield decisions — where to commit forces, when to advance, how to use the Green faction’s remaining resources after the losses of season 2 — are no longer political choices made in a throne room but military choices made in the field.
The Ser Criston Cole House of the Dragon season 3 military arc is complicated by a fundamental problem: the Lord Commander is fighting a war that, based on the broader strategic picture, the Greens cannot win without Aemond acting in coordination with the conventional forces. And Aemond, in season 3, is no longer acting in coordination with anyone.
Criston Cole’s professional competence has never been in question. His failure throughout the show has been personal and moral rather than strategic. Season 3 is the season where those personal failures have strategic consequences — where the war Cole helped start, on behalf of people whose cause was always partly manufactured loyalty, demands a reckoning he cannot manage through battlefield skill alone.
Ser Criston Cole House of the Dragon season 3 military arc is the competent soldier fighting a losing campaign — good at the tactics, unable to fix the strategy, serving a cause that has been eating itself since before the first battle was fought.

What Fire & Blood Says About Ser Criston Cole’s Fate
The Ser Criston Cole House of the Dragon season 3 fate in Fire & Blood, verified by the Wiki of Ice and Fire, is one of the source material’s most pointed moral conclusions for a character the show has spent three seasons developing as the war’s most morally compromised knight.
According to Fire & Blood, Ser Criston Cole dies at the Battle of the Kingsroad — an engagement in which the Green forces he commanded are routed by a Black faction army led by Lord Benjicot Blackwood. Cole falls in the fighting, his death occurring before the war reaches its final phase.
The Ser Criston Cole House of the Dragon season 3 Battle of the Kingsroad death is recorded in Fire & Blood with a specific historical note: it is described as “the Dance’s bloodiest battle on solid ground” and Cole’s forces were significantly outnumbered. The Lord Commander of the Kingsguard died doing what he had always done — leading from the front, in a fight he could not win, in service of a cause that was already collapsing around him.
Whether the show follows this fate exactly — given its established pattern of departures from Fire & Blood — is unconfirmed. What is confirmed is that Fabien Frankel is in the season 3 cast, and that the Battle of the Kingsroad is within the period season 3 covers.
Ser Criston Cole House of the Dragon season 3 Fire & Blood fate is the knight who spent three seasons serving bad causes with genuine skill, dying at the Battle of the Kingsroad in a fight he couldn’t win, for a king he helped crown who was never worthy of the throne. The soldier’s end, not the knight’s redemption.
Fabien Frankel’s Performance: Why Ser Criston Cole Season 3 Is His Most Complex Season
The Ser Criston Cole House of the Dragon season 3 role gives Fabien Frankel the most morally nuanced material the character has offered — because season 3 is where the person Criston Cole has built himself into finally meets the consequences of having built that person.
Frankel has played Cole throughout with a specific quality: an absolute conviction in the rightness of whatever he is doing in the moment, combined with a complete inability to sit with the wrongness of what he has already done. Cole does not ruminate. He acts, justifies, and moves on. It is the psychological profile of someone who uses forward motion as a mechanism for avoiding self-examination.
Season 3 stops that forward motion. The Ser Criston Cole House of the Dragon season 3 configuration — Lord Commander of a losing faction, military commander of a campaign he cannot turn around, loyal to a woman who is herself reconsidering her own loyalties — is the first time the character has been in a position where acting decisively is no longer sufficient to outrun his past.
Frankel’s June 9 interview with Extra alongside Olivia Cooke confirmed both actors have been given material that tests their characters at the level their three-season development has been preparing for. Criston and Alicent’s relationship — the complicated mix of loyalty, guilt, shared history, and mutual utility that has defined it — is in season 3 its most pressurised configuration.
Ser Criston Cole House of the Dragon season 3 is Fabien Frankel’s most demanding season — a character whose forward momentum has always been his defence against self-examination, now placed in circumstances where forward momentum is no longer available and what is behind him is finally, unavoidably, present.
