grimm fall finale krampus nbc 'Grimm' Season 3 fall finale spoilers: Bad Christmas and angry gators

“Grimm” is finishing off its first arc of Season 3 with a bang. An epic two-hour fall finale premieres at 9 p.m. Friday (Dec. 13) on NBC, and fans of the series can expect more of what they love in the new episodes.

Zap2it had a chance to get an early sneak peek at “Cold Blooded” and “Twelve Days of Krampus,” and they’re pretty awesome. Here are some early teases to get you excited for tonight’s two-hour event.

Someone really hates Christmas. Which doesn’t work out great, because someone else in the “Grimm” gang really loves the holiday. Expect to see some more personal backstories revealed in “Twelve Days of Krampus.”

An evil Santa might not be the scariest thing around. This two-part scarefest is putting the emphasis on the legend of Krampus, but honestly, those alligators in the sewer in “Cold Blooded” are pretty darn terrifying. Especially when you’re cornered in a sewer with them.

Adalind has bad things coming to her. Adalind has been being a bad, bad girl for the past season or so, and it hasn’t gone unnoticed. A lot of action happens in the Royals storyline in these two episodes.

Nick gets darker. The weight of being a Grimm doesn’t rest lightly on Nick’s shoulders, and his dark side does shine through in these episodes. Let’s just say that he doesn’t always hate being feared by evil Wesen.

The Wesen Council returns. As Nick starts to meet more and more Wesen he doesn’t quite understand, he starts to realize why the Wesen Council is an asset. They didn’t get off on the best foot in “Stories We Tell Our Young,” but it looks like that relationship will start to be more mutually beneficial.

Watch a tease of the two episodes below:
