The episode begins in Digu, where Jiin proposes that they cut off all ties with the Sky People, wishing to not be exploited by them. His father, the emperor, reveals that Jiin himself was a Sky person, whom he had adopted as a sign of good faith between their peoples. But Jiin has no need for such faith, and reveals that he'd poisoned the Emperor. This outrages his father, but his breath sticks in his throat and he collapses. Jiin calmly walks out of the room, and it is only once the Emperor is dead, that he feigns surprise and sounds the alarm.
