Adalind's Grimm offspring are turning out to be quite a handful.

The hexenbeist's daughter is back in the picture, along with her laundry list of dangerous powers. From telekinesis to pyrokinesis to rapid ageing, little Diana has spent the last two seasons (her kidnappings not withstanding). Now, fans are waiting for little Kelly to expose his own gift. Will he be a Grimm, a hexenbeist, or something else entirely?

David Giuntoli (Nick) and Sasha Roiz (Renard) fielded the question during a Facebook live stream.

"I don't know. There's going to be something going on," Roiz teased. "These kids are definitely proving to be pretty powerful. Diana certainly is. I can't imagine Kelly wouldn't be."

Although he couldn't give any details, Giuntoli is also confidant that Nick's son won't be your typical little boy.

"No, he'll be something," the actor answered coyly.

Unfortunately, neither Giuntoli nor Roiz could confirm whether or not Kelly's powers will bubble to the surface before the season comes to a close. In the meantime, viewers will have plenty of other mysteries to contemplate. From the Black Claw/Hadrian's Wall feud to Adalind's resurgence to the treasure of the Seven Knights, the Scooby Gang has plenty to worry about.

Next time on Grimm, Nick and Hank (Russell Hornsby) will take on another case of the week.

"When a man is found dead with all of the bones in his body seemingly liquefied and removed, Nick and Hank find themselves in the middle of a gruesome family arrangement," NBC teased. "Meanwhile, Wu (Reggie Lee) deals with a crisis of his own and Hank reunites with his old flame, Zuri (guest star Sharon Leal)."
