Grimm's Adalind has a dangerous secret, and she isn't about to spill the beans to Portland's premier monster hunter.

Adalind (Claire Coffee) was an absolute nightmare as a hexenbiest, but once her powers were suppressed, she became a rather tolerable and helpful human being. Now the mother of little Kelly and the missing Diana, Coffee's character is in no rush to return to her past.

Nevertheless, her powers came out in full force during "Into the Schwarzwald." Nick (David Giuntoli) missed all the action, and it's up to Adalind to decide whether or not she wants to let her baby daddy in on her latest transformation.

"Adalind's vulnerability at that point - she really, really doesn't want this to be happening," Bree Turner (Rosalee) told TV Line. "She feels good in who she is now, she has these pure feelings for Nick, and they have their child together. This is just going to f-k everything up."

Viewers can rest assured that it will be several episodes before Nick finds out what's really going on. According to Coffee, her burgeoning powers will "complicates things for another six episodes."

Do you think Adalind can control her woge the way Rosalee thinks she can? Find out when Grimm airs Fridays at 9 p.m. ET on NBC.
