Grimm: Inugami

"He's doing this for us."

A very odd, Japanese-themed story of the week this episode, dripping with such stereotypical themes as honour and obligation. Still, the murders are visually interesting and the killer unexpected. Oh, and there's origami. But the A plot doesn't particularly impress in an episode where we're looking for the arc stuff to provide the main entertainment value.

Arc-wise, Nick finally learns that Adalind is getting her powers back- but only from Rosalie, which isn't good. Rachel sleeps with the real Sean this time, and encourages him to marry someone else (presumably Adalind) as some rather unconventional pillow talk. It's becoming increasingly clear that something is happening to Wu, and Adalind is hired for her new job (weirdly, she's allowed to keep Kelly in the office) precisely because she's a Hexenbeist.

Rosalie and Monroe explore that tunnel leading out of Nick's and find, as well as some delightful skeletons, evidence that it leads out into the open air. But Monroe overhears Eve taking to Adalind, warning her a at from doing anything to hurt Nick. It's almost as if some of Juliette is still in there...

The cliffhanger is Rachel visiting Sean alongside a fast-aging and very striking Diana. This is all very exciting; who cares about the story of the week when so much is happening? I'm loving the arc stuff but I wish they'd do something interesting with the general format of the show.
