'Grimm': Nick And Monroe Have A Disagreement In 'Kiss Of The Muse' Exclusive Sneak Peek (VIDEO)

If you thought Juliette (Bitsie Tulloch) regaining her memories of Nick (David Giuntoli) meant that everything would be smooth sailing for the starcrossed couple in the next episode of "Grimm" (Tues., May 7 at 10 p.m. ET on NBC), think again.

The Huffington Post has an exclusive clip from the upcoming episode (above), titled "Kiss of the Muse," and as you can see, Nick and Juliette's reunion doesn't quite go according to plan, leading to a tense confrontation between Nick and Monroe (Silas Weir Mitchell). But what happened at dinner, and what's wrong with Nick? You'll have to tune in on May 7 to find out.

Check out an episode description for "Kiss of the Muse" below!

Nick discovers a muse-like Wesen (guest star Nora Zehetner, “Heroes”) with the ability to influence those she gets close to - some with positive results, others with terrifying ones. Nick must find a way to get close without losing himself in the process. Juliette (Bitsie Tulloch) arranges a dinner date with Nick in the hopes of clearing the air, but their plans go awry as the case intensifies. Meanwhile, Rosalee (Bree Turner) takes her first visit to Aunt Marie’s trailer.

"Grimm" airs Tuesdays at 10 p.m. ET on NBC.
