Did Ser Criston Cole Just Die? House of the Dragon Episode 6’s Killer Explained

He marches into the Butcher’s Ball like a man begging the bards to start writing, Alicent Hightower’s handkerchief knotted around his sword hilt and a last-stand speech practically forming on his lips. The drama never arrives. An unseen bow hums from the treeline, and Ser Criston Cole crumples into the mud before a duel can even be staged.

Three arrows end the Kingmaker.

The shooter isn’t named in the scene, but book readers will clock her instantly: Alysanne “Black Aly” Blackwood. The show’s credits back it up, listing Annie Shapero in the role. It’s a clean lift from George R.R. Martin’s Fire & Blood—Criston chasing a glorious finish, only to be cut down by a Blackwood archer who has zero interest in his theatrics.

It happens right at the top of Season 3, Episode 6 of House of the Dragon on HBO/Max, and the death lands like a hammer. Cole, the “Kingmaker” who’s spent two seasons bending the realm toward Alicent and Aegon, is gone in the space of three shots. No speech, no duel—just mud and consequence.

Who fired the shot

Black Aly is a name with weight in Riverlands lore, and the episode uses her the way the book does: as the cool, efficient answer to Criston’s operatic self-mythologizing. He wraps a queen’s token on his blade; she strings her bow. He imagines the songs; she ends the problem.

What it changes on the board

Coleon the Green side wasn’t just a Kingsguard; he was the spine of their ground campaign. Pull him out, and the map shifts fast:

• The Riverlands lose the Greens’ main field commander, opening space for Oscar Tully’s Rivermen and the Stark Winter Wolves to press harder.
• The road to Tumbleton suddenly looks a lot less defended.
• Aemond Targaryen loses the strategist who turned his impulses into action, pushing the Greens toward raw dragon power and riskier choices.
• A leadership vacuum forms: Gwayne Hightower is still standing and could take on more weight, while Queen Alicent now faces the political and personal fallout of losing the man who enforced her will.

All of it points to a single flashpoint now looming in neon: the First Battle of Tumbleton, with the Blacks driving forward and Ormund Hightower’s forces bracing for impact.
