Prior Night's Decision (前夜の決断) - S1.E20

In 1156, the former Emperor Sutoku and Yorinaga similarly oppressed, join together. Shinzei puts the two under suspicion of treason and commands the samurais to side to Emperor Go-Shirakawa. While Tameyoshi and Yoshitomo are divided over their decisions, Kiyomori, who had a talk with Emperor Go-Shirakawa alone, tells the members of the Taira family his intention of taking side with Emperor Go-Shirakawa. However, Yorimori, Kiyomori's half brother, hesitates to follow Kiyomori's decision.
