However, it's starting to make a lot more sense now.. especially because of the latest episode (#4). It appears that they're using scary mood music and environmental sounds on a show that was probably more of a light-hearted scifi drama initially (more similar to Supernatural). They've gone back and edited the show to try and change it into something more dark, sinister, serious, and more horror oriented.
I think they ripped apart Episode #4, re-shot some new scenes, and put it back together again to tell a different story. It explains why the episode makes no sense at all. (Either that, or they just have really bad writers.)
Here's why:
The episode introduces the Ziegevolk (goat people aka Bluebeards). The Ziegevolk give off pheromones that affect women within close proximity and hypnotize them.
Ziegevolk love being the center of attention, having women around them, they're very social, they never kill ("they're lovers not fighters"), and they're basically players and "Hollywood types" whose natural impulse is to reproduce with select women. That's their purpose.
Remember, they can only seduce and hypnotize women and they have a strong desire to procreate.
Then we're introduced to Billy Capra ("Capra" meaning Goat.. "Billy Goat", get it?)
He's the caretaker of the Bramble House Bed & Breakfast and he's nothing like other Ziegevolk. He's sensitive, it looks like his Mom dresses him, he has bunny rabbits in his backyard, he's a gardener, he sews and knits, he makes hand made dolls, he bakes biscuits, his house is very neat and tidy, there's glitter, he's into crafts and paper doilies, he's very polite.. did I mention he dresses "really nice" and he's very sensitive? I think you know where I'm going with this, you silly goose.
This is all confirmed right before Billy, the Grimm Detective, and his partner Hank head out into the garden. Billy rubs up against Hank and then you're shown that the pheromones are affecting him. The Grimm detective even has to ask him if he's okay because he suddenly starts acting out of character.
Before Hank was focused, but now suddenly he's hypnotized, walking in a stupor, and in an obvious trance-like state staring at Billy (having strange tingly feelings below his belt) the entire time. You can see that it's the reason why he accidentally stepped on the frog.. it's because he was hypnotized and secretly lusting after Billy the whole time.
Moments earlier though, the "newly wed girl" hugs and kisses Billy on the neck, and it had no effect on her. Billy made sure not to touch the "newly wed male", though.
Because he could seduce any woman he wanted, there was absolutely no reason why he had to kidnap them and rape them to reproduce.
They made it plainly obvious that Billy could only seduce men and that Hank was under his influence. Going by this conclusion, the episode starts to make a lot more sense now. :)
Here's what the episode was supposed to be about before they re-shot everything:
Billy is the exact opposite of his heterosexual brethren. He can only attract men, which he likes, but his species also has a strong natural drive to reproduce. Billy cannot seduce women or hypnotize them, so he's forced to kidnap women, gas them to hypnotize them artificially, and keep them sedated so that he could rape them and procreate. He tries to hold out for as long as possible, but eventually natural instinct kicks in, so he does it in large spurts before moving onto another community.
The '67 "most desirable MG ever made" Roadster was a gift to him by a man he seduced. (It was not explained in the episode, but now you're seeing that it makes more sense now and why they showed that specific scene.)
The "Blue Moon Bar" episode was probably going to be a humorous scene with their comic relief character "Monroe, the Wolfman" entering a gay bar and ending with hilarious results.
And then there's Hank who probably had scenes where he was wrestling with his new "funny" feelings towards Billy.
The producers probably thought it was all too offensive or just too silly/funny for being so early into the series, and they wanted the episode to be more serious and dark. So they re-used old cuts and re-shot new scenes. Voila, you get this masterpiece which makes no sense.
This was definitely not bad writing. They vastly changed the script and created new scenes. This is a very bad sign for the series.. last minute (major) changes, no forward thinking, there's no clear direction for the series, they're changing the tone of the series to make it more serious (trying to match their competition?).. it's chaotic and simply being thrown together.
Even the episodes are being aired out of order. "Three Bad Wolves" was originally supposed to be aired as #3 or #4 (or both), but it was moved to #6.
Without the inappropriate horror music, though, the other episodes are pretty funny. I actually like Grimm as a comedy drama.
