Grimm's Sergeant Wu is about to have a crisis of epic proportions.

The cop was let in on the big Wesen secret last year, and since then, Wu (Reggie Lee) has seen his fair share of supernatural baddies. Unfortunately for the Nick's (David Giuntoli) friend, running with a Grimm has serious risks.

"We can't say much about it right now, but look for Wu to have quite a story arc later this season," TV Line teased earlier this month.

After the events of "Lycanthropia," it appears as if Wu's little side journey will take him down a road of full moons and bloody cravings. After all, a scratch from a werewolf is nothing to sneeze at. Although Wu started to undergo some sort of transformation back in episode 14, but the story might not pick up again until episode 18, "Good to the Bone."

"When a man is found dead with all of the bones in his body seemingly liquefied and removed, Nick and Hank (Russell Hornsby) 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)."

Set to air on April 22, "Good to the Bone" will be followed by the ominously titled "The Taming of the Wu." Whatever is going on with Wu, it's going to take the whole Scooby Gang to turn the situation around.

Do you want Wu to become a Wesen, or do you want Nick and co. to find a way to reverse the scratch? Perhaps Nick's new mystery stick can save the day. Sound off in the poll below!
