Jason Lannister

Lord of Casterly Rock, twin to Tyland — golden, gallant, and convinced of it. He once courted the princess with the Rock's splendors and was declined with prejudice.

The fuller tale

Lord of Casterly Rock and twin to Tyland, Jason Lannister is golden, gallant, and entirely convinced of both qualities in himself — a man who once courted Rhaenyra directly with the Rock's considerable splendors on offer, and was declined with a thoroughness that apparently did nothing to dent his confidence.

When the Dance breaks out, Jason commits the western lands' considerable martial resources to the greens' cause with the same self-assurance that characterized his failed courtship years earlier, marching his forces east to make his mark on a war he seems to regard as another arena in which his obvious qualities will naturally prevail.

The page and the screen

The show's current seasons have not yet reached Jason Lannister's military campaign or its outcome; Fire & Blood covers his march and its end in considerably more specific detail than the series has had occasion to dramatize.

The books: Fell at the crossing of the Red Fork (F&B, ch. 5)

The Lord of Casterly Rock took his gallantry to war and died of it early, cut down at the crossing of the Red Fork by a grizzled squire named Pate — knighted for it as Pate of Longleaf, the Lionslayer.

The series has not yet reached this stage of the war; Jason Lannister's fate remains ahead of the current seasons.

Fire & Blood has his gallantry catch up with him early: he falls at the crossing of the Red Fork, cut down by a grizzled squire named Pate who is knighted for the kill and remembered afterward as Pate of Longleaf, the Lionslayer — a considerably less distinguished end than Jason's own self-regard would presumably have predicted for him.
