Oh Captain, My Captain (Grimm)

The episode received positive reviews from critics, who praised Giuntoli's direction and the character development.

Opening quote: "You will face yourself again in a moment of terror..." Nick (David Giuntoli), Hank (Russell Hornsby), Monroe (Silas Weir Mitchell), Eve (Bitsie Tulloch), Wu (Reggie Lee) and Rosalee (Bree Turner) discuss their next move against Renard (Sasha Roiz), who is also demanding Hank's and Wu's resignations.

Adalind distracts Renard from attending his inauguration speech and Renard watches as Nick impersonating him, announces his resignation from the mayor office and states that Nick was part of an undercover investigation to bring "the real killer" to justice, planning to resume his career as police captain.

Adalind arrives with Diana (Hannah R. Lloyd) and Kelly and works on another potion to reverse the shift.

He also adds that he will raise Diana and threatens that something will happen if he dies and if he finds another shiftier like him, the deal will end.

Diana arrives and after seeing that he isn't her dad, she uses her powers to push him away, making him go back to his normal body.

He stares in shock when he finds Meisner (Damien Puckler) there, telling him that "he chose the wrong side".

On the last day of shooting, the cast and crew threw a party for Giuntoli, giving him also a clapper board with his name written on it.

It's easily the best episode of season six and a contender for one of the show's top ten, finding a way to both get our characters out of the hole they're in and break up the bleakness with some body-swap levity.

"[7] Kathleen Wiedel from TV Fanatic, gave a 4.4 star rating out of 5, stating: "Oh, the sweet taste of revenge.

Not only did it move the plot along — Nick's no longer a fugitive, the action can refocus on police matters, Adalind's free of Renard's clutches — but it offered some pitch-perfect light moments, too.
