“Tribunal” picks up exactly where “Wesenrein” left off with Monroe (Silas Weir Mitchell) shackled, standing among a sea of cloaked figures chanting “Wesenrein” over and over. “Grandmaster” Charlie Riken (Brandon Quinn) presides over the so-called trial accusing Monroe of “violating the law” by “marrying outside of your bloodline” and “the befriending of a Grimm.” Back at the precinct, Captain Renard (Sasha Roiz) is concerned about Sgt. Wu (Reggie Lee) so he asks Nick (David Giuntoli) and Hank (Russell Hornsby) to make sure Wu can handle it when a Wesen “woges.” Meanwhile, Juliette (Bitsie Tulloch) and Rosalee (Bree Turner) continue to review the wedding guest list to figure out who betrayed Rosalee and Monroe to the Wesenrein.
