Game of Thrones Season 6 Episode 03 Oathbreaker
Bran is confused as to why Dayne has the upper hand as his father used to recount about how he killed him in the fight when the injured Howland Reed sneaks up behind Dayne and stabs him in the neck, after which Ned finishes him.
BRAN: He’s better than my father.
THREE-EYED RAVEN: Far better.
BRAN: But father beat him.
THREE-EYED RAVEN: Did he?
BRAN: I know he did. Heard the story a thousand times.
