Everyone is aware of the road conditions in King's Landing, and Jamie's tumble on the ground has utterly ruined his expensive leather outfit.
However, everyone present has been on a battlefield. There, guts and intestines get slashed, and human and horse excrement mix with blood on the ground, yet aren't those who need to cut and fight still doing so?
For those who have seen battlefields, although these things are still disgusting, they no longer cause physical nausea.
"Kingslayer, you truly are the disgrace of the White Sword Tower."
Balistan said through gritted teeth, disappointedly.
The White Sword Tower is the residence of the Royal Forest Iron Guard in the Red Castle, and it's said to be the symbol of knightly spirit in the Seven Kingdoms.
And Jamie Lannister having an affair with the wife of the person he swore loyalty to... this made the old Balistan feel the world had become absurd.
With the backbone captured, the Lannister soldiers were quickly disarmed.
