Why would you kill your boss in order to save the life of your sworn enemy? When the Grimm returns for its sixth and final season January 6, it will pick up right where the Season 5 finale left off—with Capt. Sean Renard (Sasha Roiz) wondering what the hell made him rescue his arch-nemesis Nick Burkhardt (David Giuntoli) by stabbing Black Claw supervillain Conrad Bonaparte (Shaun Toub) through the gut with a sword.
