'Grimm': Adalind Drops a Baby Bombshell on Nick (Exclusive Video)

This week on 'Grimm,' Nick's rough season gets even worse.

Poor Nick (David Giuntoli). 

It's not been a smooth season four for the Grimm. He opened the season minus his powers. To regain them, he had to sleep with his girlfriend, Juliette (Bitsie Tulloch), but only after she'd been magically transformed into evil Hexenbiest (and Nick's archenemy) Adalind (Claire Coffee). The "side effects" from that kinky process were less fun: Sweet, caring Juliette is now a raging Hexenbiest who not only broke up with Nick, but is enjoying her powers so much that even psychotic Adalind is scared. Juliette broke bad and nobody in Portland is safe.

But, as this exclusive clip reveals, things are about to get a lot worse for Nick. Viewers have known for weeks that Nick and Adalind's season three one-night stand (don't ask) led to the fertile Hexenbiest getting pregnant again (for the second time in four seasons). Now, Nick gets the news.

How much more can one Grimm take before he loses it?
