Complete story — includes the ending
Monroe is on trial by the Wesenrein for a ritual that is performed called the "Tribunal". Nick and Hank train Wu to deal with woged wesen, which allows him to confront Officer Jesse Acker, who is secretly a part of the Wesenrein, but without leverage, he cannot force him to turn on the group. Juliette and Rosalee scour the wedding guest list, provided by Trubel, with help from Bud, to find anyone who would have exposed them to the Wesenrein. Opening quote: "May the God of Vengeance now yield me His place to punish the wicked."
