Lady Ellyn Tarbeck, Roger's sister, was present at the feast in the Westerlands where the betrothal of Genna Lannister and Emmon Frey was announced. While Ellyn laughed, the Red Lion left the hall in anger.
Later the Red Lion rebelled against his liege lord, Tytos Lannister, alongside the Tarbecks. This time Tywin Lannister, Tytos's heir, lead the Lannister response. Both houses were exterminated. A song known as the "The Rains of Castamere" was composed as a commemoration of the event.
