Few characters in House of the Dragon divide fans as much as Ser Criston Cole. Some viewers see him as a tragic knight destroyed by duty and heartbreak. Others consider him one of the story’s most frustrating villains. Searches for terms like Ser Criston Cole actor, why does Ser Criston Cole hate Rhaenyra, and how does Ser Criston Cole die continue to surge because his actions shape many of the most important events in the Targaryen civil war.
Introduced as a talented but relatively unknown knight, Criston rises from humble beginnings to become one of the most influential figures in Westeros. His relationships with Princess Rhaenyra Targaryen and Queen Alicent Hightower transform him from a respected Kingsguard member into a central player in the conflict known as the Dance of the Dragons. Portrayed by Fabien Frankel, the character has become one of the most discussed figures in the franchise due to his complicated motivations, shocking decisions, and dramatic evolution.
This guide explores who Ser Criston Cole is, why he matters, his relationships, major storylines, and his ultimate fate in both the show and George R.R. Martin’s source material.
Who Is Ser Criston Cole?
Ser Criston Cole is a knight from House Cole, a minor noble family from the Dornish Marches. Unlike many powerful nobles in Westeros, he does not come from a wealthy or influential bloodline. Instead, his reputation is built entirely on his skill, discipline, and success in combat.
His rise begins when he impresses the royal court through his combat abilities and earns a place in the Kingsguard. Princess Rhaenyra Targaryen personally supports his appointment, a decision that changes both of their lives forever.
Why Criston Stands Out
Several factors make him unique:
- He is one of the few major characters without significant political power at birth.
- His entire identity is built around honor and duty.
- He experiences dramatic shifts in loyalty throughout the story.
- His personal choices directly influence the succession crisis.
These traits make him more than just another knight; he becomes a catalyst for war.
Ser Criston Cole Actor: Who Plays Him?
The role of Ser Criston Cole is played by Fabien Frankel, an English actor born in London in 1994. Before House of the Dragon, Frankel appeared in projects such as The Serpent and Last Christmas. However, his portrayal of Criston Cole brought him worldwide recognition.
Fabien Frankel as Ser Criston Cole
Frankel’s performance has earned praise even from viewers who dislike the character. His portrayal captures:
- Criston’s internal conflict
- His rigid sense of honor
- His bitterness after personal betrayal
- His transformation into a political and military leader
Many fan discussions acknowledge that Frankel brings nuance to a character who could easily have become one-dimensional.
Ser Criston Cole and Rhaenyra
One of the most important relationships in House of the Dragon is between Criston Cole and Rhaenyra Targaryen.
How Their Relationship Begins
Criston initially serves as Rhaenyra’s sworn protector. Over time, the two develop a romantic and sexual relationship despite his Kingsguard vows requiring celibacy. This creates a severe conflict between personal desire and duty.
Why Does Ser Criston Cole Hate Rhaenyra?
The answer is more complicated than simple rejection.
Criston believes he has violated the most important oath of his life. To restore his honor, he proposes that he and Rhaenyra leave Westeros together and marry. Rhaenyra refuses because she intends to remain heir to the Iron Throne.
From Criston’s perspective:
- He sacrificed his honor.
- He expected a shared future.
- His proposal was rejected.
- He felt emotionally abandoned.
This rejection evolves into resentment that eventually influences many of his later decisions.
A Rarely Discussed Insight
Many viewers interpret Criston solely through modern relationship dynamics. However, within Westeros, a Kingsguard oath represents a lifelong sacred commitment. His crisis is not merely romantic disappointment—it is the collapse of the identity he spent years building.
Why Did Ser Criston Cole Kill Joffrey?
One of the show’s most shocking moments occurs during Rhaenyra and Laenor Velaryon’s wedding celebration.
Who Was Joffrey Lonmouth?
Joffrey Lonmouth was Laenor Velaryon’s lover and one of the few people who knew about Criston’s relationship with Rhaenyra.
Why Did Criston Kill Him?
After Joffrey hints that he understands Criston’s secret, Criston becomes overwhelmed by guilt, fear, and emotional instability. He brutally kills Joffrey during the celebration.
Many fans search for:
- Why did Ser Criston Cole kill Joffrey?
- Why did Ser Criston Cole kill Laenor’s lover?
- Why does Ser Criston Cole kill Laenor lover?
The answer lies in a combination of factors:
- Fear that his secret would be exposed.
- Emotional devastation after Rhaenyra’s rejection.
- Self-loathing over breaking his vows.
- A complete loss of self-control.
The killing marks a turning point from which Criston never fully recovers.
Ser Criston Cole and Alicent
Following the wedding incident, Criston’s life changes dramatically.
How Alicent Saves Him
After killing Joffrey, Criston contemplates suicide. Queen Alicent Hightower intervenes and prevents him from taking his own life.
This act creates a powerful bond between them.
Their Political Alliance
Over the years, Criston becomes Alicent’s most loyal supporter. He helps advance the interests of her children and becomes one of the Greens’ most influential leaders. Eventually, he rises to:
- Lord Commander of the Kingsguard
- Hand of the King under Aegon II
His loyalty to Alicent becomes one of the defining features of his character.

- The consequences of war
- Criston’s growing cynicism
- His political influence
- His struggles with guilt and responsibility
Many viewers who disliked him in Season 1 began to see additional layers in his character during these episodes.
How Old Is Ser Criston Cole in Season 1?
The show never provides an exact age.
However, based on available timeline clues, Criston is generally believed to be in his early-to-mid twenties when he first appears.
By later seasons, substantial time jumps place him considerably older, though the television adaptation compresses aging compared to the source material.
Because exact ages remain unconfirmed, estimates vary among fans and analysts.
Does Ser Criston Cole Die?
Yes.
One of the most frequently searched questions is:
Does Ser Criston Cole Die?
The answer is yes, although the details depend on whether you’re discussing the television adaptation or George R.R. Martin’s Fire & Blood.
How Does Ser Criston Cole Die?
In Fire & Blood, Criston meets his end during an event known as the Butcher’s Ball.
As the war turns against him, he attempts to continue fighting despite increasingly difficult circumstances. His enemies refuse the heroic single combat he seeks and instead kill him with arrows during the conflict.
Why His Death Matters
His death is significant because it rejects the romantic ideal of knightly warfare.
Criston spends much of his life believing in honor, reputation, and battlefield glory. Instead of receiving a legendary duel, he dies in the brutal reality of war.
This serves as one of George R.R. Martin’s recurring themes:
- War is rarely noble.
- Heroes do not always get heroic endings.
- Reputation cannot protect someone from chaos.
When Does Ser Criston Cole Die?
For book readers, Criston’s death occurs during the later stages of the Dance of the Dragons.
For television viewers, the timing depends on the show’s adaptation schedule. Recent developments suggest the story is moving toward the events that ultimately lead to his downfall.
Who Killed Ser Criston Cole?
Another common question is:
Who Killed Ser Criston Cole?
In the source material, he is not defeated in a dramatic one-on-one duel. Instead, opposing forces kill him during the Butcher’s Ball through a coordinated attack involving archers.
This ending deliberately subverts expectations and reinforces the harsh realities of the conflict.
What Happens to Ser Criston Cole?
By the end of his journey, Criston evolves from:
- Honorable knight
- Royal protector
- Secret lover
- Political operator
- Military commander
His story becomes a cautionary tale about obsession, wounded pride, loyalty, and the destructive consequences of civil war.

Unique Insight #3
His arc mirrors the larger tragedy of the Dance of the Dragons itself: good intentions slowly transformed into irreversible destruction.
