Grimm season 4 returns tonight, Friday, 27 March at 9pm on NBC.
Episode 15 is titled, Double Date, where Juliette turns to Captain Renard for help.
According to the official synopsis: "Nick (David Giuntoli) and Hank (Russell Hornsby) are called to investigate a one night stand turned deadly when a man finds himself in the middle of a very bizarre love triangle. Captain Renard (Sasha Roiz) hopes Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) can help him deal with recurring incident of phantom bleeding."
Meanwhile, "Adalind (Claire Coffee) makes a discovery that might turn the tables in her favour and Juliette (Bitsie Tulloch) makes a big decision that could change the course of her relationship with the Portland Cop, " states the synopsis.
It was confirmed in Bad Luck that Adalind is pregnant, but whose baby is it?
"Yes, Nick is the father," Claire Coffee tells Tvline. "It is insane. And now that she is a Hexenbiest and they're really pushing her character into such a dark place and Bitsie [Tulloch] is doing such a great job working with all of that new, evil energy, they're using this as a way to push that even further."
"We're about to shoot 19th episode where everybody finds out. "Okay. Let's take a minute to figure out who the father is." She knows it's Burkhardt's, but publicly, I think she's trying to figure out which father will benefit her the most," she added.
Last week's installment left fans wondering what the Grimm is going to do now that he knows that his girlfriend, has transformed into a Hexenbiest.
Meanwhile a new promo suggests that the newly turned Hexenbist will turn to Captain for help to get away from her boyfriend.
Will they hook up? Given their previous history of "love", this seems like a possibility.
