It was the evening of Joffrey's coronation, and you couldn't find your sister anywhere. The frivolities and festivities raged around the city in anticipation of the upcoming nuptials of Joffrey and Margaery Tyrell, and you had a small window of free time before your Kingsguard duties returned.

You had planned to spend that free time wearing your sister out.
