Skye, 30, will play a kind, mild-mannered bed and breakfast owner named Robin Steinkeller, who also happens to be a Seltenvogel (an extremely rare bird-like creature). Robin has something very valuable to many in the Wesen world, and Nick (David Giuntoli) finds her in a panic to escape her abusive husband. So far, her only protection is the strength of her turtleneck and scarf, whatever that might mean. Perhaps her neck gets cold easily?
No airdate has been set yet for the episode, titled "The Thing with Feathers."
Skye's guest turn reunites her with Buffy the Vampire Slayer executive producer and writer David Greenwalt, now an executive producer on Grimm. Greenwalt also re-teamed with Buffy vet Amy Acker for the upcoming Feb. 10 episode in which she plays a black widow.
Skye most recently guest-starred on American Horror Story last year.
Grimm airs Fridays at 9/8c on NBC.
