In the pilot Sweet Dreams is playing on the runner's iPod when we see her murdered and also when the police arrive on the scene, was she listening to it (and nothing else) on repeat? Why would Nick assume that it would have been playing at the time of the murder?
Either the jogger had it liberally sprinkled in the playlist, she had an extremely long remix, or since it was left playing it just happened to come back around to Sweet Dreams by the time the police found it.
Or she could have just had that one song on repeat and no playlist at all.
No real in-universe explanation but the out of universe explanation is probably a modern version of the broken watch on a dead body. That body gets attacked violently, probably breaking the watch which then stops at the time of the attack. Same premise just... not really understanding how technology works.
Is it really that improbable that someone would listen to the same song over and over again? Fridge Brilliance: She just really likes The Eurythmics, and Hank saw that the iPod was on repeat when they found the body so they know that the song was playing when she was killed. Furthermore, the song was stuck in the killer's head because it was repeating over and over again as he ate her.
Weird as it is, this troper will actually put a song on repeat as a musical timer, like if I know something I'm doing should take about the run legnth of a song, then I'll set that song and when I hear it repeat then I know I've gone over time. Maybe the runner wanted to do something similar, maybe she was timing her run to the song.
A better question about the Pilot is why they later concluded that their suspect humming this well-known song is proof that he must be their killer? Granted, they're right, he's guilty, but what reasonable person would assume that he could only have heard that song from her iPod, as opposed to any number of other places (a coffee shop, for example, or a store. I work at a thrift store and that song has played over our PA system before). Not to mention the fact that the guy is old enough to have heard the song when it was released.
It wasn't, realising it was the same song merely was enough for them to turn around and go back to double check. At which point the subject turned all his lights off and tried to make a runner. Basically he confirmed his guilt by jumping the gun.
It's also possible that it was accidentally put on repeat when she was killed. Like the breaking the watch reason, the watch ends up breaking due to a major impact. While thrashing about, the iPod may have accidentally had a button hit that put put the song on repeat.
After the end of "Tarentella", how is anyone not in on The Masquerade going to explain how the arrested Spinnetod aged into an old woman overnight, or that she has a regenerated finger with an exact print match to the severed one found at the scene of the first murder? Even if Captain Renard takes steps to cover it up, how would he do so without attracting suspicion from Nick?
Perhaps Renard acknowledges the unusual condition and has her sent to a hospital for caretaking... only she has a heart attack on the way there and dies. IE he retires her to a Wesen home where she lives her days in anonymity. Nick might get suspicious but Renard might gamble on the general lack of knowledge Nick has as well as the general obscurity of Spinnetods. Still, it's a stretch to be sure.
Weird stuff happens. People might question it, sure, but no one is going to look at her, go "Huh, what a strange happenstance," and conclude "She must be a spider-person!" It doesn't really need to be covered up.
"Last Grimm Standing". Why does Monroe split at the end when the cops come? At first, yes, it's so he's not caught where he's not suppose to be as with other episodes. But a few scenes before, Nick explicitly told Hank that Monroe had/was following a lead for them ("... he found a guy that was doing bets...") so it's not like Monroe's involvement was a mystery or unofficial. And if he was officially helping out, then Monroe being in the cage and fighting would not be unusual (nor would he be charged with any wrong doing since he wasn't trying to kill anyone) since he could legitimately say what happened - he was helping out with a lead, got caught, and forced to fight.
Did he run? I don't remember that...
In Monroe's defense, he had no way of knowing that the police had been filled in on his involvement. For all he knew, he really wasn't supposed to be there
One thought might be that while he was there in an official capacity, when the police came, he and Nick had been in a fight. This would mean the police would want to give medical attention to Monroe (plus, pull evidence from the other fighters and such). However, due to Monroe's past (recent and otherwise), something as simple as doing a blood test by the police might result in him getting arrested. So if the police had arrived before Monroe had to fight, he might not have had to run since there wouldn't be any evidence linking Monroe to any of his past crimes.
How did Nick and Monroe know what address to send the severed Reaper heads to? And, for that matter, how did they send a package containing two severed heads without anyone inspecting it?
Maybe they searched them and found a letter with an address? But the second part not through regular post, too many check points and scans.
If Hexenbiests are an all-female race... why is Renard "half-Hexenbiest"? Shouldn't EVERY Hexenbiest featured thus far count as such?
Renard has also been stated to be of royal Grimm ancestry, by NBC's website.
As it turns out, hexenbiests aren't an all-female race. They just don't call male members hexenbiest. Rather, they're called zauberbiests.
If Kelly Burkhardt is trying to keep news of her survival quiet, wasn't telling hospital staff "if you have a problem with my son, you deal with me" a really bad idea, even if she was trying to buy time? She's been cautious enough not to tell her adult son, who has inherited the Grimm legacy and won't be left alone if only because of that, that she was alive...and then she goes and tells some nurses that she's the mother of their patient's cop boyfriend. Because that will never get back to the enemies she was trying to protect him from.
In "The Good Shepherd", the Nuckalavee was wearing leather gloves while it was searching Nick's home. When Juliette came in it hid in the bathroom and changed to its Wesen form. But the Nuckalavee has hooves in that form...so what happened to the gloves?
Woging seems to be a weird combination of both a meta-physical and physical transformation. It's possible that there is some minor physical change but most of what actually happens is more of a meta-physical effect that happens to be able to cause physical effects.
Also he could have been doing a partial woge. He may have changed his face but not his hands. We saw Monroe change his hands but not his face in "Dance Macabre" and we've seen multiple Wesen only woge their eyes.
The Coyotl's name and ritual iconography seems to be drawn from Native American sources, but in human form they present as degenerate Scots-Irish. Why?
It could be that Coyotl have interbreed over the years. The couple in "Chupacabra" were Coyotl and of Latino descent.
The 2x10 episode "The Hour of Death" features a wannabe-Grimm serial killer. While torturing his victims, he wears a black mask that clearly doesn't cover his eyes. Since Wesen can identify Grimms while woged based on their eyes turning black, shouldn't he have been concerned that his victims would notice that he wasn't actually a Grimm? It never comes up in the episode because his victims don't woge in the moment, but if his plan was to eventually work with Nick, how was he going to keep his non-Grimmness a secret?
Black Claws whole plan to win Renard the Mayor position seems to hing on selling him as a wholesome family man, and forcing Adalind and her kids to play the part, but what about all the people who have known Renard. Why doesn't anyone in the prescient question how none of them knew about a wife and two kids? especially since Diana looks to be somewhere around 6-9 (despite really being about a year old). It's heavily implied that Black Claw has more than enough reach to fudge things like Birth and Marriage certificates, but all it would take is one or two people from Reynards "normal" life to come forward and say "hey the chief never mentioned a kid before now" or "Hey wasn't that Adalind chick the reason Burkheart broke up with that Juliette chick awhile back? Didn't they have an epic fight right in the middle of the station?". How is it no one is remembering any of this and calling out the whole happy family charade?
Many Blutbad (including Monroe) drive Volkswagens. Blutbaden are wolf-like Wesen. Volkswagen is based in Wolfsburg.
Why does Nick always catch the cases with Wesen involvement? Because Captain Renard always assigns them to him. Figure that even if Renard can't always know for sure, he's better at spotting the telltale signs of such crimes than Nick would be.
Even more than that...what if homicide cases have always had a large number of wesen victims and perpetrators... but no one ever knew because they couldn't see them?
This is borne out by the huge number of Wesen prisoners seen when Nick and Hank visit a prison. Also when Wu asks Renard about that and Renard replies that most crimes are Wesen-related.
In "Happily Ever After", why did the step mother run away screaming if the Wesen killer was known to her? Because the Wesen in question wanted her to see their Game Face and so she was running away from what she saw as an actual monster.
Roddy's DJ name is Retchid Kat a.k.a "Wretched Cat". Why go with such a name? Firstly, his father could easily be replaced with a *cat* and seeing as he and his father are ratfolk... what would they hate more than cats?
The traditional allies of the Grimms are the same creatures in fairy tales that help the protagonists. Same applies for traditional enemies and neutral parties.
Blutbaden are the source of the modern day meathead — Monroe's "diet, drugs and exercise" to control most of his more violent tendencies combined with the volatile nature of many Blutbaden describes your stereotypical jock.
"He's a cop and a Grimm? Is that even legal?" This line may seem like just Hap being stupid, until you consider that a large part of the non-human community defines Grimm as synonymous with Serial Killer (or at best, a vigilante). From that perspective, the question is a bit more valid.
Given that at least two types of non-humans gravitate towards politics (heck, JFK was one), it may very well be that Grimms weren't exactly operating within some sort of unspoken law.
And on top of that, Grimms are intimately linked with the royal politics of the Wesen world. There probably *are* laws and traditions about what Grimms can do for a career.
"Island of Dreams", a Wesen and Nick discuss this a little bit as sort of a double life. It may be less of a law or rule and more the demands of being a Grimm.
JFK being a Ziegevolk might have contributed to his assassination in this universe. After all, would -you- want a nigh-irresistible charmer at the head of a powerful country? Other heads of state would never be able to accomplish anything since he could simply charm them into doing otherwise.
The show seems to have most of their non-human murders done through impaling, stabbing, slashing, rending, and so forth with none done through bludgeoning or what not. This makes sense when you consider that the various non-humans would be more comfortable acting on instinct and natural abilities - and since they all have forms based off animals, very few animals bludgeon things to death. Likewise, the snake character in Of Mouse and Man, what does he do to the mouse character for intimidation? Put him in a choke hold (constricting).
The location itself is a bit a fridge brilliance if you know one thing about it. Portland OR actually has its own city motto. That motto is KEEP PORTLAND WEIRD, (if you ever go there youll actually see a billboard with this logo near the highway). What better setting for a show like Grimm then a city that has so embraced its own weirdness.
Why is it so many Wesen seem to be in Oregon? Now that we know theres an evil organization that some of them are trying to escape over in Europe, which coast is further from Europe again?
Also, Renard is in Portland and trying to build up his power. He's establishing his own court, which makes Portland a haven for refugees.
It seems to be implied that they're all over the place - just from what we've been told in the show, Wesen have been in: Germany, of course, New York, Seattle, Phoenix, St. Lois, Antwerp, France, Greece, Japan, Brazil, and Spain. The show just focuses on the Portland area, so those are the main ones we get to see. Besides, the European ones seem to have no trouble booking a flight for their agents if something needs to be taken care of in Portland.
Back in Game Ogre, it's mentioned that the Ogre killing rifle was associated with royalty. Since we now know that Grimm are associated with the seven royal families, a member of the families had the gun commissioned for the Grimms. And since Nick was in the hospital, when the gun was used it's leading Renard to think that another agent of the royal families was in town.
"Leave it to Beavers" and the episodes preceding it give a good reason as to why Grimms would typically not be police officers and otherwise live on the fringes of society (human and otherwise). From a relationship perspective, there's the Reapers. But from a pure human society perspective who knows nothing about Reapers and Wesen, having to spend every other week hiding bodies doesn't exactly go hand in hand with normal life very easily or otherwise explaining the various perils.
Freddy Calvert's terror of Nick first comes across as the standard "Oh God, it's a Grimm, please don't kill me," but a key member of The Resistance should be braver then that. Then we learn that the Grimms have been working for the Seven Families, which means he had a very good reason to fear that he had been found out and the Grimm was there to kill him.
The plot twist in "Woman in Black" can be seen in hindsight. We're told from the very first episode from Marie herself that Grimms usually can't live a normal life. And what's more normal than trying to raise a kid. Not only that, we have come to learn that Grimms usually have a really hard time living within the bounds of the law/within normal society. So that Nick's mother is alive and perhaps faked her own death in order to allow Nick to be raised with Marie who was already dying from cancer makes sense. His parents protect him from threats and keep him safe while their enemies assume they're dead.
There's foreshadowing as far back as the pilot: if Grimms get their sight when a close relative who already has the sight dies, and we're never told about any age limit, Nick should have gotten his when his mother died and not when Aunt Marie died... except his mother didn't die.
Realizing this, the writers retconned the original concept so that Grimms' sight is genetic, that it skips some individuals, and that the only thing that is certain is that females gain the sight at an early age while males gain it much laternote like how girls enter puberty earlier while boys continue developing into their early 20s.
Stories about cultures eating other people or eating various animal parts for special powers... those stories come from non-Wesen witnessing Wesen and attempting to 'gain' their powers. Or perhaps Wesen themselves initially believing that they were what they are because they took powers from animals. So in the same way that human bits are medicinal for Wesen, the reverse may also be true.
Also, given there are perfectly real potions that you can work no matter your species, whose to say they were wrong?
Fridge Brilliance if youve ever been to Portland. The location where Adalind and Nick duke it out in Love Sick Is close to a place known to locals as Witch Castle, a place subject to many local legends.
We've never gotten to see Captain Renald's Game Face, and we know he can tell who's a Wesen and who's a Grimm. Going by what we've seen so far, that means that either Renald is a Badass Normal like the Grimms (we know there are other human families with similar abilities, like that monster hunter from Japan), or, if he is a Wesen, he has yet to suffer Glamour Failure (onscreen at least), because he never loses his composure.
According to NBC's official bio, he's a Grimm of royal descent. Which would turn his comment about losing heads into another Fridge Brilliance since what's the traditional way Grimms are killed and how did they kill people in the Revolution? Yup.
He is actually a half-Royal Grimm half-Hexenbiest
According to Rosalee in "The Sandman", he is technically a Zauberbiest, a "wizard beast".
Why do Coyotl seem to show their Game Faces much more often than other Wesen and have an intermediate phase? Well in real life, coyotes have actually thrived with human expansion. Most aren't particularly afraid of humans at all while being very adaptable to urban environments. Urban coyotes even seem to live longer than their rural counterparts. So if Coyotl follow the same sort of adaptability and such, they might simply be more comfortable among humans and in urban societies than other Wesen.
Add to that, Hank, a normal human, is not only the best friend of a Coyotl but the godparent of one as well. Your theory of their feeling all right near non-Wesen does have some good back-up to it.
Why did Monroe turn the digital clock facedown in "The Good Shepherd"? Because it was red, a colour that triggers Blutbad! Nice callback to the first episode.
Also, of course, he's an expert in analog clocks and watches as well. So he probably finds digital clocks simple and inelegant.
Why does Ryan wear a mask when doing the vigilante killings in 'Hour of Death'?. Because if he didn't, then the victims would recognize that he's not actually a Grimm. And also, how did said person know Bud was an Eisbieber?. Well, naturally, Bud Woged in front of Nick while talking about said killings and he saw.
He wore the face mask, but it very clearly doesn't cover his eyes. Those Grimms wore black masks and black hoods so that when a Wesen woged, they would see a pit of infinite darkness in a field of black. But Ryan's eyes would have stayed normal.
Ogre killing and ogre killing guns were traditionally associated with royalty. Nick has one. This should have been our first clue that the ruling class were Grimms (or similar) themselves and that Grimms use to work with them. This in turn should have clued us in as to what Renard was involved with as well as some of the motives behind his family/organization.
Rosalee is an Emotionless Girl to an extent. This can be chalked up to her past, sure, but also remember she's a fuchsbau who are naturally talented at lying. Which means she probably also has a good poker face/more accustomed to hiding her expressions.
How was Hank, a normal human, able to take down the Coyotl leader with one punch? Because he hit him in the nose, which is a weak spot for canines (dogs, coyotes), and blows to that area are very painful.
And, of course, Hank is a fit, largely-built police officer, who was running on adrenaline at the time. He probably delivered a punch that would have at least knocked Muhammad Ali back if it hit him square in the kisser and he was unprepared for it. Knocking the coyotl out cold with a surprise attack (the coyotl wasn't the one expecting to be attacked or surprised) wouldn't have been too hard.
Hank's last name is Griffin. The Griffin is a Greek mythological creature that is part-eagle and part-lion. This is an interesting name for a character on a show based on and inspired by mythological creatures.
Monroe's eagerness to join Nick seems odd at first, considering he is supposedly a villain turned pacifist. Then you find out that his villainy consisted of things like avenging Molly when her boyfriend slashed her face. Monroe was always a vigilante.
In "Volcanalis", testing the royal baby's blood makes a concoction turn blue, confirming the unborn child is indeed royal. What are people of high stature sometimes called? Blue bloods.
In the retconned version of how Grimms get their powers, girls tend to develop the abilities young while men gain theirs later in life. How many fairy tales feature young girls who draw the attention of monsters and the older, militant men who kill the monsters?
Juliette No Sells Joe's woge with a dimissive: "I'm not impressed." Which initially appears to be a Badass Boast... and then you remember that she's seen Monroe in full woge. A Blutbad is definitely a lot scarier than a Klaustreich.
You can tell that Monroe has an estranged relationship with his parents from their first conversation. Not only are they surprised to hear from him, he also had to manually enter their number into his phone. He doesn't even have them in his contact list.
"Monroe" is most likely Monroe's given name, since that's how his mother addresses him. No clue as yet what the family name is; even their coat of arms is labelled "Blutbaden".
Monroe's and Rosalee's descriptions of a Grimm's eyes sound an awful lot like Nietzsche's famous line on monsters and the abyss: "Battle not with monsters lest ye become a monster and if you gaze into the abyss, the abyss gazes also into you." Hmmm...
In retrospect, Juliette's Hexenbiest transformation was very subtly foreshadowed in the second half of season 2, in Renard's nightmare of her turning into a hag-like creature. How long did the writers have this planned?
Why does Reynard do a 180 when it comes to Adalind? Well, be she his daughter or his niece, that little girl of hers is a bastard, hybrid, Royal-Hexenbeist. He can easily relate, whatever her actual blood-tie to him is. It's possible he'd get protective over any such hybrid and their mother.
The big reveal behind the copycat Jack The Ripper he's a wraith AND the original and he's possessing Renard explains why witches DON'T resurrect people for loads of money: because it usually leaves the target prone to being demonically possessed by a homicidally insane wraith of some sort, and would explain how La Llorona works: an inexperienced grieving mother trying to resurrect her children would be prone to backlash, killing her and continuing the cycle.
The chest containing the Treasure the Seven Grimm Knights stole from Constantinople is made of bronze, a detail that at first glance seems inconsequential, until one realizes that an iron chest may have rusted away to nothing eventually. The Seven Knights meant for that chest to last forever.
The Season 5 Episode "Lycanthropia" features a lycanthrope. These are caused by a rare genetic disorder among Blutbaden that basically turns the afflicted into a werewolf. Monroe wonders how there are any of them left at all, since Blutbad families would typically kill any children that exhibited lycanthrope characteristics. So, why did the family in the episode not kill this lycanthrope as a child? Because, as Nick mentions, "This family is old, old money, from the late 1800s." The lycanthrope was the only heir!
The Season 6 episode "Breakfast in Bed" features a Wesen that feeds on chemicals produced during sleep and causes insomnia, and the prime suspect for most of the episode is a wheelchair-bound old man. When the culprit turns out to be someone else, he woges into a red herring-like Wesen and laughs maniacally. Sneaky.
The turns Adalind and Juliette make though both avoidable are understandable when you realise Juliette's worst quality is a lack of faith, while Adalind's best is that she'd do anything for those she sees as family. The accidental conception hits Juliette's weakest points and forces Adalind to use her best point. Juliette's lack of faith is what in the end destroys the relationship. Her actions are what put it beyond repair. And Adalind choosing Nick and his friends as her family is what cements her heel-face turn.
Imagine the potential damage or boon to civilization that a frog-eating Ziegevolk plus the Coins of Zakynthos would do. You'd have a someone able to naturally influence people combined with coins that are suggested to have caused the rise of empires like the Roman Empire... and Nazi Germany.
Maybe Ghengis Khan was such a man. Lead an empire, and left a lasting imprint on the genetics of most of East Asia.
We see a hint of this in "One Angry Fuchsbau". Said ziegevolk is a lawyer with few scruples. Not only does he supercharge his abilties, he uses his abilities to effectively completely reverse people's memories of an event.
At the end of "'Tarantella" we see Nick and Hank taking the daughter of the Monster of the Week, a Spinnetod, to live with family now that her mom's been arrested. That in and of itself is sad, but not fridge horror. What makes this fridge horror is that while their taking her away it's made perfectly clear that this young girl is also a Spinnetod....which means when this girl grows up she's going to have to go through the same damn thing her mom just went through. Either that or "retire" and face rapid aging. Not a happy future.
This troper was under the impression that by "grandma", Nick meant "Charlotte", and that the girl would be taken in to that "monastic home" for Wesen seeking peace. Better than being forced into serial murder by one's own nature, but still a Downer Ending for that girl who thought she had her whole life in front of her.
That might work if Nick was alone and willing to alter state documents about the girl. But seeing as Hank was there, and that girl is seen in the eyes of the law as just another citizen who probably does have some family outside of her parents, then they where probably honestly going to take her to them. And even if they did take her to Charlotte, she would still be faced with the same decision between killing or aging.
Given that both her parents are Spinnetods, her grandmother is probably one too. She would teach her how to hunt.
Go back and re-watch the showdown between Adalind and Nick. Is this troper the only one who got serious Attempted Rape vibes from the way he was pinning her down?
It's probably intended to be symbolic in the same way that fairy tales typically were. That is, a prince uses his power to take away the wild magic of women in order to turn her into a normal woman. Less about rape and more a throwback/shout out to symbolism in fairy tales.
Also it could be that Nick was trying to evoke this reaction from Adalind in order to get her to bite him (thus getting his blood into her system and break the curse on Hank)
I assumed that that was the plan from the get-go. I figured Nick's plan to be something like this: 1. Fight Adalind. 2. Kiss her, making her think I'm trying to rape her. 3. She bites the shit out of me, and swallows my blood. 4. No more magic, Hank is cured.
For that matter, in "Plumed Serpent", Ariel pins Nick to the ground, unbuttons his shirt and forcefully kisses him. And later on, when Nick returns home to caress and kiss who he thought was Juliette, only to find that it was Ariel in the bed.
This is even more creepy, considering that in Season 3 Adalind disguises herself as Juliette and sleeps with Nick to take away his Grimm powers. This gets her pregnant. In Season 5, when the child is born, they have to settle their differences for the son's sake... and they actually start to fall in love.
There were definite Attempted Rape vibes. A man pinning a woman down, forcing sexual contact in order to strip her of her power? Yeah, it doesn't get any more blatant than that. I find it very disturbing that people seem to gloss over Nick's sexual assault while at the same time condeming Adalind for raping Nick later on. Nick's act to get rid of Adalind's power is actually listed in the Awesome page, while Adalind's actions to rid Nick of his power is strictly always talked about negatively, when both should be condemned.
Because the audience knows what Nick's intentions are and that his only goal is to get her to consume some of his blood. Consider that the only reason it has Attempted Rape vibes is because the individual sees a man being aggressive towards a woman and ending up on top of her. Which was the end of both of them fighting to kill each other. Would you view it the same had it been any other combination of fighters?
In "The Other Side" the attacks themselves are brutal enough, but can become ten time worse when you consider one possibility. Wesen don't always show their "faces" when they attack, so the last things those kids might have seen was their friend doing that to them.
Juliette's hallucination in "Natural Born Wesen" had her trapped in the foyer of her house for roughly 24 hours. A night, a full day and at least part of another night passed while she was left sitting on her stairs alone.
"Endangered". The fact that there are wesen who hunt other wesen for their woged skins... and the fact that there's actually a market for that sort of thing.
"Best Served Cold". The only thing that saved Monroe from a horrible fate was the fact he's a sworn vegetarian and his girlfriend playfully held him to it.
Rosalee tells Juliette that many wesen have a problem showing themselves, even to other wesen, and that understanding is a rare thing from humans. This puts an additional meaning to wesens' fear of Grimms: If they don't like revealing who they are, how disturbing is it to face someone who can see it anyway?
The description of what wesen see in Grimms in "Synchronicity" makes this even more profound: When a woging wesen looks into a Grimm's eyes, they see pools of infinite darkness that reflect their wesen nature back to them. It's no wonder it took Rosalee time to get used to it...
Rosalee told Juliette that difficulty coming to terms with her identity as a wesen fuelled her Dark and Troubled Past. When telling Monroe about her first woge, she mentions that her brother Freddie made it seem like something was terribly wrong with her. Although she laughs it off, it does make one wonder how that impacted her...
Kelly Burkhardt thinks that Diana has a great destiny in store because of her early powers. However, when one looks at history, people who are given great unchecked power...don't tend to use it very well. Someone like Diana who has been given enormous power at such an early age would be almost impossible to discipline. And given the things she has done so far with her power, such as stick a pen through a man's eye to kill him, manipulate Meisner into bringing firewood into the log cabin byprojecting her image, light a fire in the fireplace, almost crash a plane, destroy Nick's house, and break Monroe's clocks with telekinesis. And the whole coffee in a skull shape can't be a good sign either. Just what kind of impact is she supposed to make on the world? And another InUniverse horror to consider is the last time a wesen with a supernatural advantage managed to change the world. What was his name? Oh, yeah. Hitler.
Trubel didn't have anyone to explain her Grimm nature to her because she was orphaned at a young age. Considering the risks of the Grimm life, it's not hard to guess how her biological family probably died. Also, orphaned Grimms who learn who they are the hard way is probably not that unusual an occurrence.
The Wesenrein launch a campaign of harassment against Monroe and Rosalee for two different Wesen types marrying. (He's a Blutbad, she's a Fuchsbau.) Now that Juliette's a Hexenbiest, imagine how they'd react to a wesen dating a Grimm.
Probably by wetting themselves. Nick alone has already shown himself capable of taking down almost anything. Throw in a Hexenbiest? Attacking them is like attacking Superman married to Wonder Woman.
The events of "Beeware" become a lot more significant and dangerous for Juliette now that she's a Hexenbiest. In "Beeware", Nick sours the relationship between the Mellifers and the Grimm. The episode also reveals that Mellifers are mortal enemies of Hexenbiest. Juliette is now the perfect target for revenge.
Null and void since she's dead. But they might come after his son.
In "Iron Hans," a vengeful Juliette sets Nick's trailer on fire. While that can symbolize Juliette merely burning a bridge to complete her Face-Heel Turn, the impact that the loss of the trailer could have on future Grimms is perhaps the worst part. That is centuries of knowledge and lore passed down through the generations, all lost. And how much has Nick relied on that knowledge in order to defeat the Wesen he's up against? He might not even be alive today were it not for that book. While he is an experienced Grimm now, and whatever knowledge he retained he will pass down to future Grimms, we still don't know if any of the weapons survived the fire. That knowledge will be pointless without any specialized weapons with which to kill those Wesen who require it, and worst-case scenario, it could potentially mean extinction for the Grimms.
Thankfully the next episode reveals most of his weapons have survived, but not all. Likewise he has lost many of his potions and is down to only a few books that have survived the blaze. But what will happen when he comes across a new Wesen, one that Monroe and Rosalee don't know much about. He's going to have to fight it potentially blind.
Also Just before that Wu had been binge reading a lot of those books, so he could possibly help recover some of it from memory. Hank to when it comes down to it. Heck they've all helped search through the books a time or two, so while they'll probably never recover all of it they can at least scrape together something of a start
This is Jossed as of 5x10. Monroe's uncle, an antique books dealer in Leipzig, comes across a recently deceased Grimm's collection. Hank hangs a lampshade with his comment: "Looks like we got our trailer back."
Kelly mentions to Nick that she and Marie had started to show their Grimm abilities when they were ten. Monroe reminisces several times about his Wesen friends from high school, and there have been many remarks throughout the series that Wesen are basically everywhere, living among normal humans. Imagine being a Wesen teenager who asks a girl out for the high school prom, only to find out that not only is she a Grimm, but her father is as well.
Just imagine this scene playing out:
Kelly (age 7): [crying] Daddy, that boy is being mean to me! Walter Kessler: [sees the kid's parents woge] Don't worry, sweetie, I'll handle it.
Marie Kessler was a librarian. As in, the person at the library that every parent tells their children to go to for assistance. In all the time that Marie was a practicing librarian (about 25-30 years) how many encounters did she have with Wesen parents that ended with them running terrified out of the building, with their children in tow? How many of those Wesen did Marie subsequently hunt down?
The only reason that Nick isn't a decapitate first, ask questions later Grimm is because he didn't have his family around to teach him about this stuff. Nick learned how to protect and help people from being a police officer for his entire adult life. If Nick had gotten his Grimm abilities ten years earlier, Marie (and probably Kelly too, if there had been a way to reach her) would have taught him everything he needed to know about being a typical Grimm.
