"One Night Stand" is the fourth episode of the supernatural drama television series Grimm of season 3 and the 48th overall, which premiered on November 15, 2013, on the cable network NBC.
A group of teenagers, Jake Barnes (Michael Welch), Dan (Pritesh Shah), and Sarah (Sara Fletcher) and Anna Mahario (Lauren Luiz) are relaxing on a river.
Nick (David Giuntoli) and Hank (Russell Hornsby) are notified by the sheriff that Dan's body was found and had claw marks, deducing he was dragged.
Renard (Sasha Roiz) is told by Sebastien (Christian Lagadec) that Adalind (Claire Coffee) was dealing with Frau Pech about the baby, which may have royal blood.
They arrest Sarah and Anna and after they leave, Abel confronts the neighbors Dominic (Derek Ray) and Jesse (Coltron James) as they are the real culprits.
Although they know he's innocent, Nick and Hank use the confession to make Sarah and Anna reveal that Dominic and Jesse are the killers, as their old tradition would require them to take care of their children.
Club's Kevin McFarland gave the episode a "B" grade and wrote, "Though Grimm stumbles in broad strokes, occasionally it manages to win me over with a surprising attention to detail.
That depth of backstory without calling direct attention is impressive, and touches like that make 'One Night Stand' an enjoyable episode in spite of some repetitive flaws.
"[4] Nick McHatton from TV Fanatic, gave a 4.2 star rating out of 5, stating: "There are some episodes of Grimm that tell so much procedural story it sometimes grows boring rather than compelling.
