This is about Game of Thrones S2 finale episode "Valar Morghulis". In the scene where Tywin Lannister is named as the the "Hand of the King" and the "Saviour of the city" by Joffrey Baratheon, Tywin Lannister enters the King's court on his stallion rather than by walk. Not to forget, his horse s*its just before entering the throne room.
What is the significance of him entering the court room on a stallion and not on foot? What does the horse s*it add to the scene?
The Lord of Casterly Rock made such an impressive figure that it was a shock when his destrier dropped a load of dung right at the base of the throne. Joffrey had to step gingerly around it as he descended to embrace his grandfather and proclaim him Savior of the City.
