‘House of the Dragon' season 3 episode 6 kills off another major character

House of the Dragon delivered a shocking twist as latest episode leaves a fan favourite’s fate uncertain.

In season 3, episode 6, which premiered Sunday, July 26, on HBO, another major casualty took place as Criston Cole is killed in brutal battle.

Facing overwhelming odds in the Riverlands, he chooses to stand and fight despite knowing death is likely.

He is struck by multiple arrows and dies carrying a keepsake from Alicent Hightower, marking the end of one of the show's most divisive characters.

The episode also seemed to include the death of another major character who has been around since season 1.

The episode leaves Steve Toussaint’s character Lord Corlys Velaryon, otherwise known as the Sea Snake since the premiere episode of the Game of Thrones prequel series, in grave danger.

He is ambushed and choked by enemy Ormund Hightower’s soldiers. While it was not fully confirmed that Corlys died, he was attacked and collapsed to the ground before the episode cut to black, leaving his fate up in the air.

These events continue a deadly season that has already seen the deaths of Jacaerys "Jace" Velaryon in the premiere and Otto Hightower in Episode 2.

Otto Hightower (Rhys Ifans) returned in the second episode, but, was killed at the end of the episode.

With only two episodes remaining, the conflict is escalating rapidly, and more major losses are expected.

New episodes of House of the Dragon drop Sundays at 9 p.m. ET on HBO.
