A Knight of the Seven Kingdoms showrunner admits cutting a major line from the novella was "a mistake": "That scene was in the script at one point, then fell out"

Peter Claffey as Dunk in A Knight of the Seven Kingdoms.

While A Knight of the Seven Kingdoms is so far a very faithful adaptation of George R.R. Martin's source material, a few changes have been made to the story of the hedge knight Dunk and his squire Egg.

Two of these changes, though, were actually just mistakes on the part of showrunner Ira Parker.
