The pair form an unlikely friendship as result of Nick oftentimes calling upon Monroe for help. Most times Monroe is consulted for his knowledge pertaining to creatures of the Wesen world, usually whenever the information offered by the books and diaries inside Aunt Marie's trailer proved insufficient at providing Nick with any assistance. In addition, Nick has come to rely on Monroe's support in various capacities: Monroe has helped from tracking suspects to protection to clandestine investigative methods. He met his fiancée Rosalee whilst helping Nick on a case.
Nick Burkhardt encounters Monroe while investigating a series of disappearances, the latest being a young girl named Robin Howell. Monroe came to Nick's attention when Nick sees him woge into a wolf-like creature, while watching a group of passing children. The police search Monroe's house, but find nothing.
Nick, still suspecting Monroe, stakes out Monroe's home at night. In order to get a better view of the Blutbad's activities, Nick gets closer to the house. He observes Monroe in his backyard "marking" his territory. Monroe realizes he is being watched and goes back inside his house. Nick is ambushed by Monroe, who jumps through a window.

In "Bears Will Be Bears", Monroe again assists Nick by guarding Aunt Marie when her police protection is canceled. Monroe arrives at the hospital, and he and Marie have a terse conversation, which is interrupted by Monroe noticing men that are stalking Marie's hospital room. He follows one of the assassins down into the hospital basement, and is ambushed by a second assassin. Monroe assumes his Blutbaden form and severely beats the two, tearing off the arm of one of the assailants. Monroe then leaves quickly so that he isn't caught at the scene. Before leaving, Monroe phones Nick to tell him that he has to abort protection detail and warns him to get to the hospital because he isn't sure that he got all the assassins. As Monroe flees, a man dressed as a priest attacks Marie, but she fights back and kills him just as Nick arrives. Sadly the stress was too much for her weakened body to take, and she dies in Nick's arms.
In "Beeware" Nick calls Monroe to meet him at the paper mill. Monroe explains a little about the habits of Mellifers and follows a scent to an office, where Nick finds an envelope addressed to Melissa Wincroft. Monroe is at first a little irate but agrees happily enough, though he says "Don't you dare say heel!" when Nick tells him to wait up. Nick teases him a little by saying "Good boy." Nick and Monroe then go to a mansion where they find the floor covered with dead bees and proceed up the main staircase until they reach the upper floor where they find large hives.
After researching in Aunt Marie's trailer, Nick goes to ask Monroe for more information. Monroe explains that Ziegevolk exert a pheromone that attracts women, giving an example of someone he knew. It is from Monroe that Nick learns that the Ziegevolk who eat toads are breeders. Their pheromones are more powerful and can even make men attracted to them. Monroe enters a bar, following Billy Capra, but has to leave because the Ziegevolk's pheromones were "way too potent."
Monroe tells Nick about Reinigen, and how they are at the bottom of the food chain. Nick then asks Monroe to talk to Roddy Geiger, as Roddy knows that Nick is a Grimm and therefore distrusts him, and convinces Monroe to by describing Roddy's talent with a violin. Roddy is playing a Brahms concerto when Monroe arrives, which Monroe comments on. When Monroe says that he is a friend of Detective Burkhardt, Roddy tries to close the door, but Monroe catches it, partially woging and revealing his Wesen form. This causes Roddy to back away in fear, proving Monroe's point that "Reinigen and Blutbaden are not drinking buddies." Monroe tells Roddy about how Nick isn't like other Grimms and that Nick is worried about Roddy. Monroe then proceeds to try to lecture Roddy on "not being stupid" and how he has talent. Monroe then leaves feeling proud of himself.

She then ran off and scavenged. Monroe was nearly killed by two rednecks that were trying to kill Holly to avenge their brother, but Holly killed one, and Nick shot the other. Holly had become especially close to Monroe as she had never met another Blutbad, not knowing what she was, and because he and Nick protected and cared for her, as shown when she hugged him after saving his life, and when she grabbed his hand when she was afraid he wouldn't come back when he left to get her some burdock root for the pain of her gunshot wound.
In "Game Ogre", Hank is attempting to face Oleg Stark, an ogre. As Nick is hospitalized, he gives Monroe the key to his aunt's trailer so he can take the weapon needed to kill Stark.

He goes with Nick, Juliette and Rosalee to the container yard, and knocks out one of the zombies so that Rosalee can administer the cure. While Nick leads the zombies away he ensures that the ladies reach the van and are inside before they are surrounded.
Inside the car surrounded by zombies, Monroe with Rosalee and Juliette drives around the container yard to get away from the zombies. Most of the zombies are dislodged, but two remain on top and one on the hood. Monroe decides to race towards a container, and at the last minute he brakes sharply, throwing the zombies into the container. He then drives away, but enters a construction zone where the car becomes stuck in a trench. As the car can't move, they exit the car and climb up a crane onto some containers, and fight off the zombies. The attack is so severe that Monroe has to woge in order to keep them from being overrun.
At the spice shop Monroe is about to call some people that are willing to risk their lives for Nick to go to Austria to save him when Rosalee realizes that the antidote could be delivered as a gas. They all work to produce the cure.
They return to the container yard and explain to the skeptical police that they have a cure, but they need the container to be opened. Monroe borrows a baton from one of the officers and by banging on the side of the container leads the zombies away from the entrance while the others open the door and throw in the antidote. As the police open the door to a group of confused citizens, Monroe receives a call from Hank telling him that Nick's plane has crashed, giving him the location of the crash. Monroe, Juliette and Rosalee go there in Monroe's Volkswagen. At the site, they arrive just as Hank is informed of the 911 call from the bar, so they all go there.
At the bar, Monroe says that Nick was definitely there as he recognizes his scent. He goes into the bar with Hank and Renard, then follows the scent outside into the woods.
Monroe continues his attempt to sniff out Nick in the woods, with Hank following closely behind. He catches Nick's scent several times, only to lose it again. Sean Renard calls them and they inform him of their failure to find Nick before letting him know where they are. Yet again losing Nick's trail, Monroe and Hank grow exasperated. Just then, Nick begins his assault on a family that lives near the woods and the duo hear the family's screams. They manage to arrive just in time before either the husband or Nick can be seriously harmed. They briefly struggle with Nick, who is much stronger than both of them combined. At one point, Hank chucks a statue at the back of Nick's head, but Nick catches it without looking, amazing both Monroe and Hank. They come up with a plan to lead the disorientated and very angry Grimm out of the front door, but Monroe messes up the plan by knocking over a lamp by accident. They, however, eventually manage to lead Nick into an old barn, where the latter falls through the flimsy floor and is trapped temporarily.
Sean, Juliette, and Rosalee arrive. Monroe and Hank brief them on what is happening and together they convince the husband of the family not to shoot Nick. Nick has recovered and is banging about the barn trying to get free, and the team confronts him in apprehension.
Monroe and Sean woge (at which Hank expresses envy) and attack Nick together. They manage to get in several hits with a shovel and a wooden board, but Nick continues to have the upper hand. The battle is halted when Juliette distracts him and sticks the Piqure-Gigantesque into Nick's stomach. She is slapped out of the way, but Rosalee manages to inject Nick with the antidote. Nick turns on Rosalee, and Monroe tries to protect her. Nick collapses as the antidote takes effect. On the drive home, the team tries to keep Nick warm. Monroe expresses his anger with Sean's brother, telling Sean to "not let him get away with it." The team lets Nick rest in the spice shop, handcuffing him when he starts thrashing around unconsciously.
When Nick wakes up, Monroe, along with everyone else present, attempt to answer his questions at the same time. They decide to let Juliette have the honors. Later on, when the team (sans Nick) finds out that someone had died under Nick's attack, Monroe agrees that it isn't Nick's fault because he didn't know what he was doing.
Monroe is later seen cleaning out the aftermath in the spice shop with Rosalee.
Monroe and Rosalee are having a lovely dinner date at the restaurant Raven & Rose. Monroe awkwardly tries to invite Rosalee to move in with him. Rosalee teases him, pretending not to understand his meaning, before agreeing. A waiter brings them some tartlets as compliments of the chef. Monroe wistfully stares as Rosalee eats his portion due to him being vegetarian. Just then, one of Monroe's old friends, Sam, walks past with his wife Kimber. They exchange friendly greetings and part ways.
Later, Monroe helps Nick pack his stuff as the latter is moving back in with Juliette. Nick inquires if Monroe has eaten at Raven & Rose before and explains that the restaurant is run by Bauerschwein. Despite the feud between the two species, Monroe seems indifferent to that fact. Monroe then blocks Nick's view with a large moving box, before removing it and exclaiming "surprise!" as Juliette, Hank, Rosalee, and Bud emerge from the kitchen to throw Nick a party to celebrate him moving out.
Before they can celebrate however, Monroe gets a phone call. It's Kimber who is worried that Sam hasn't come home yet. Monroe confirms Nick's suspicions that Sam had eaten at Raven & Rose's, and that Sam is a Blutbad, as well as another of the victims who died after eating at the restaurant. Monroe, however, feels fine, breaking the pattern. Nick asks Monroe what he eats and Rosalee figures out it was the tartlets that everyone ate. She says she needs to get to the spice shop. At the shop, she figures out that a mushroom is responsible.
Monroe accompanies Nick and Hank in locating Sam, and watches helplessly as Sam explodes in a tree. Pained at his friend's gruesome demise, and alarmingly enraged, he swears to kill the Bauerschwein, even snapping at Nick's attempts to rationalize with him.
At the spice shop, Rosalee tries to calm the wrathful Monroe to no avail. Nick assures Monroe that he would handle it, but Monroe refuses, declaring it a fight between Blutbaden and Bauerschwein. He also states that it would be "open season on [the Blutbaden]" if he let Ostler get away with it. He woges in anger and storms out of the shop.
As Ostler leaves his restaurant, Monroe begins following him. Ostler notices him, but is backed into an alley where he is surrounded by multiple Blutbaden. Monroe closes in on Ostler, seemingly about to atatck him. Nick and Hank arrive, and Nick attempts to talk Monroe out of it while Hank keeps an eye on Ostler. Monroe and Nick end up in a brief scuffle, in which Nick shoots Monroe, seemingly fatally. The remaining Blutbaden howl intimidatingly, and Nick threatens to leave Ostler in the alley until Ostler agrees to confess to killing the other Blutbaden. After the detectives arrest Ostler and pull away, Monroe opens his eyes and smiles.
At the precinct, Monroe tells Nick that he actually did hit him during their "fight" and Nick comments that Monroe did too.
Monroe helps Rosalee move into his house. Rosalee begins to have doubts on moving in, not wanting to fill Monroe's house with her junk. Monroe reassures her that he'll just get rid of some of his stuff, but has trouble deciding on what. He eventually picks up a glass ornament, but begins rambling on about its history. Rosalee smiles, puts the ornament back where it belonged, and they start kissing.
Nick and Hank later come over to ask about the Wesen they saw. Rosalee suggests that it sounds like they're dealing with a Naiad. Monroe is tempted to go and help on the case, but feels bad leaving Rosalee unpacking alone. She reassures him that it's alright, and he gladly leaves.
At the trailer, Monroe finds an entry in one of the Grimm Diaries about an encounter with a Naiad in 1755.
Later on, back at home, Monroe finds something that looks like a Chia Pet in one of Rosalee's boxes. Monroe pretends to like it, trying to appease Rosalee, but Rosalee hates the thing as much as he does and they stuff it back into the box.
Monroe is exercising at home when the phone rings. Rosalee answers for him, finding to her surprise that it's Monroe's mother on the other end. Monroe's mother does not know about the two's relationship, and Monroe fills her in. She seems happy for Monroe.
Later on, the team discuss the brutal attacks over dinner. They rule out the possibility of it being either a dog, wolf, coyote, or Blutbad as Monroe says there is too much "general mangling." When Nick describes Ray Bolton's woge, Monroe and Rosalee suggest that it might be a Höllentier.
At the spice shop, Monroe and Rosalee are visited by Nick and Hank. They explain vaguely Wesen/Human genetics.
Later on, Monroe and Rosalee help Nick and Hank figure out that Daniel Keary is a Grausen. Rosalee wants to report Daniel to the Council, as per normal procedure, but Monroe argues that that means Daniel will be killed. Rosalee is firm about it because if they don't tell the council, then they would probably be killed.
In the middle of the night, Monroe answers a knocking at the door. He thinks it's Nick at first, and is frustrated until he sees that it is Alexander from the Council. Rosalee tells him about Daniel and his location, and he leaves gratefully. Monroe locks the door behind him and insists that they have to tell Nick. After doing so, Monroe wants to come with Nick to protect Daniel, but Nick refuses due to the danger that it could put Monroe and Rosalee in.
Nick and Hank visit Monroe to ask if he knows a wesen that could inflict the type of injuries suffered by Scott Himber. Nick suggests a Siegbarste, but Monroe says that they suffer from claustrophobia. He thinks that it is probably a Gelumcaedus, and suggest that they all come for dinner with some books from the Trailer.
When Nick calls to ask what "Dēcapitāre," means Rosalee answers as he is busy working on a clock.
Part 1, "A Sore Subject"Edit
Bud Wurstner shows up at the spice shop to meet Monroe and Rosalee, whom Nick Burkhardt recommended he see regarding his hair loss problem. Bud asks if Rosalee has a remedy for hair loss for his "friend", and satisfied with their answer, he excitedly leaves.
Part 2, "A Helping Hand"Edit
Monroe helps Rosalee in making the hair regrowth formula, but does not exactly follow Rosalee's instructions
Part 3, "Friendly Neighborhood Eisbiber"Edit
Bud returns to thank Monroe and Rosalee for preparing the formula "for his friend." Rosalee also tries Monroe's "creative" baking, which involved making a dandelion-seaweed cookie.
Part 4, "Late Night Crisis"Edit
Bud comes into Rosalee's shop panicking because his hair (and his friend's hair) is growing out of control. Rosalee and Monroe say that they know that the cure was for Bud, and that his hair looks okay. Bud brings in John Oblinger who is also suffering from extreme hair growth. Rosalee and Monroe then have to wash the cure into both Bud and John's hair.
Growing up, Monroe was a (mostly) typical Blutbad. While dating Angelina Lasser, he accidentally killed Alvin Perkins, Sr., a forest park ranger. When she tried to convince him not to worry about it, he vowed to reform his way of life and signed up for a support program. Among his support program buddies were Angelina's brother Hap, Larry Mackenzie, and Lemuel "Smitty" Smith. As part of his new reformed lifestyle, he has kept a close eye on the now-needy Perkins family to make sure they are making ends meet; they are oblivious to his assistance. ("The Icy Touch")
Today, Monroe is a Wieder Blutbad, or a reformed Blutbad that no longer lives on the wild side. ("Bears Will Be Bears") He grew up in Half Moon Lake, New Hampshire, where his parents, who are non-Wieder Blutbaden, still live. ("Endangered") He has not always been this way, and in the past he, along with fellow Blutbaden Hap and Angelina, did live in a more dangerous fashion. While he still has feelings for Angelina, Monroe is no longer in a relationship with her, and is mostly happy with his current peaceful life. ("The Three Bad Wolves") Monroe's family has had many run ins with Grimms, so it is likely they do not share his view point.
While Monroe doesn't know German very well, he is able to read it at a basic level, struggling with pronunciation, but generally close. High German was his grandfather's muttersprache, so he knows enough German to help Nick at a basic level in his research. ("Three Coins in a Fuchsbau") Monroe is also able to read Spanish. ("Happily Ever Aftermath")
His great-great-great grandfather was a cartographer in Colmar, which is today part of Alsace, France. When his heirlooms were saved from a fire in the Franco-Prussian War, Monroe inherited a ton of things that were once his. ("Endangered")
At the beginning of the series, Monroe was shown to be somewhat an amoral character: he doesn't prey on humans, but at the same time, does nothing to prevent other Blutbaden from doing such. He claims this is because maintaining his solitary existence from others of his kind encourages them to follow likewise. He was also very hostile towards Nick; in "The Three Bad Wolves", he yells at Nick about Angelina Lasser. He later develops high moral standards thanks to his interactions with Nick, as seen when Nick insisted on him helping to track down Holly Clark; Monroe was initially reluctant, until Nick showed him Holly's picture. By the time he was attacked by a pair of Reapers for helping Nick, Monroe had reached a point where he enjoyed working with Nick to shake up the status quo, rejecting Nick's attempt to assure Monroe that he would no longer ask him for help.
As an individual, Monroe possess a rather laid back personality and is usually calm and level-headed in most situations, although he can slip into a slight panic at times, such as asking questions which he then answers himself. To go with his laid back personality, Monroe possesses a somewhat dry sense of humor often making puns and sarcastic remarks. Monroe is also slow to anger although he does become slightly irked when someone or something prevents him from doing his daily Pilates. One of Monroe's strongest personality traits is his kindness and loyalty to those whom he considers to be his friends which he has demonstrated many times toward Nick and Rosalee, and has romantic feelings toward the latter. In "The Kiss" he was visibly angered when Catherine Schade came back at the Spice Shop to retrieve her orders from Rosalee, threatening her in the process; Monroe later appeared (he was working behind the counter) saying that 'cheapskate' came very close to getting her throat ripped out. He is shown to be protective of Rosalee and does not take kindly to anyone threatening her, such as when he woged and attacked Edgar Waltz ("Cat and Mouse") and Barry Kellogg. ("One Angry Fuchsbau")
Accordingly, he is often devastated or distraught when he learns that something terrible has happened to anyone he considers his friend, as seen when his Wildermann friend, Larry died ("Big Feet") and when Angelina died. ("Over My Dead Body") Monroe also seems to be fond of decorating his house extensively. Monroe is very good with children who love to trick or treat at his house at Halloween due to his excessive and elaborate lawn decorations, and the large amount of candy he gives. Monroe even defended a girl against the neighborhood bullies who were trying to steal her candy. Not only did Monroe force the bullies to give the candy back to the girl, but he also yanked on the ear of leader bully until the group apologized to the girl for stealing her candy. ("La Llorona") Monroe is also very creative and takes pride in his creations. Of course, not everyone appreciates his creativity: Rosalee isn't very enthusiastic about his baking after trying his dandelion-seaweed cookie ("Bad Hair Day").
Another defining trait of Monroe is the fact that he seems to believe in the inherent goodness of Wesen, not just his own kind. He consented to accompanying Nick in locating Holly Clark into the woods, ("Let Your Hair Down") and was shocked when two Blutbaden robbed a bank while in their Wesen forms, taking it as a personal insult for their species. ("Natural Born Wesen") He later went to a Wesen bar, hoping that someone there could provide some information, despite knowing that "less than legitimate" Wesen were the patrons. He was also very keen to accompany Nick and Rosalee to help the Glühenvolk couple. ("Endangered")
Monroe is a noticeably tall man, standing several inches taller than Nick and an inch or two above Hank. As a result of his vegan diet and daily pilates, Monroe has a lean and slightly muscular build; appearing slightly weedy. He has brown eyes when untransformed and brown hair which is lightly wavy. He sports a thin beard. In Wesen form his facial features become sharper and more pronounced taking on a somewhat chiseled appearance. His hair goes from wavy and hanging to standing up on ends, forming a widow's peak hair line; while his beard becomes thicker.
Nick Burkhardt - Nick Burkhardt is Monroe's Grimm friend. Monroe and Nick got off on the wrong foot at first and Monroe was hostile towards him because he was a Grimm, but eventually realized that Nick was not like the Grimms that he had heard about from his parents. The two later became very close friends, always helping out each other.
Powers and AbilitiesEdit
As a Blutbad, Monroe has all the standard capabilities of his race. Strength, speed, resilience, acute senses all these attributes present while in human form are enhanced even further when he woges into his Wesen form. Furthermore, as a Wieder Blutbad, Monroe states that he's much weaker compared to what he otherwise would be had he been living out in the wild, hinting that he has yet to reach his full potential due to the civilized lifestyle that he chose. But in exchange, he has demonstrated sufficient control over his woge, and has shown being able to partially enter it, selectively wogeing parts of his body at will, as seen in Danse Macabre, where he summoned claws from his right hand to intimidate Roddy Geiger, or in Let Your Hair Down, where his eyes turned a fierce red color.
During confrontations, Monroe usually fights unarmed, preferring to use his Wesen abilities and attributes to his advantage by using his claws and fangs as weapons. Though at some cases, he was seen being able to best other fully-transformed Wesen without having to Woge himself. However, he has shown some aptitude at wielding actual weapons, as seen in Game Ogre, where he quickly figured out how to use a Siegbarste Gewehr in time to save Hank from Oleg Stark, and where he taught Nick the proper way of handling a Doppelarmbrust. ("Leave It to Beavers") In "Last Grimm Standing", Monroe states that he took up boxing at some point.
Monroe is a highly intelligent man, and is a jack of many trades. Most notably, Monroe is highly knowledgeable when it comes to other Wesen; likely stemming from Portland's diverse Wesen population. While he claims that what he knows about the various Wesen out there is incomplete, the knowledge he provides is none-the-less a valuable asset to Nick and is usually enough for Nick to cope on his own. He also displays a degree of expertise in translating foreign languages, namely Spanish and German. Since helping and taking over the spice shop for Rosalee, Monroe has become a highly skilled apothecary. Furthermore, Monroe has very large collection of antiquities passed down to him from various ancestors from a variety of professions. Many of these antiquities have led Monroe to understand things that most others, including other Wesen, wouldn't understand in today's modern world.
- Monroe has a very strict regimen to avoid any relapse of losing control with his innate Blutbad instincts. "How do I stay good? Through a strict regimen of diet, drugs, and Pilates" ("Pilot"). He's very strict on his pilates schedule and finds great annoyance with any interference with it, shown when Nick came over Monroe's home at 6:30am asking for Monroe's help ("Bears Will Be Bears").
- While Monroe has maintained a strong control of his Blutbad instincts, he says it could be dangerous for him to associate himself with a 'wild' Blutbad as he could relapse because Blutbaden are dangerous in a pack, especially when they see red. One such example is when he housed Angelina, who reminded him of the 'old days' and convinced him to accompany her to the woods, where they proceeded to kill a rabbit and eat it which completely goes against Monroe's principles, as he is vegetarian. ("The Three Bad Wolves")
- Monroe was born and raised in the New Moon Lake area of Barnstead, New Hampshire. ("Endangered")
- Monroe's favorite color is red. ("Organ Grinder")
- Monroe enjoys collecting model trains and stamps. ("Let Your Hair Down") ("Three Coins in a Fuchsbau")
- Monroe's surname has never been said nor has it been seen in props. The house number on Monroe's mail box is 418; the box does not bear a name. ("Pilot") His parents, likewise, are known simply as Alice and Bart. ("The Wild Hunt")
- Monroe loves the Christmas Holiday. He enjoys decorating his home in all manner of Christmas decorations, including a valuable antique train set. He has a Santa suit, and says he makes a good Santa, even though Santa Claus is not a Blutbad, but a Gefrierengeber, a different sort of creature, one that can easily survive in arctic conditions. ("Let Your Hair Down")
- Monroe drives a 1974 Volkswagen Beetle. ("Lonelyhearts") ("Quill") ("Over My Dead Body")
- Monroe lives at 418 Ravensview Dr, Portland, 97210. ("Over My Dead Body")
- Monroe attended Brown University for graduate school (unknown major or undergrad). He told Hap this when he let him borrow his alma mater shirt ("The Three Bad Wolves").
- Monroe wears plaid-patterned clothing frequently.
- Monroe is an accomplished cellist.
- Monroe's front door sports a stained glass window featuring a coat of arms surrounded by a forest. The coat of arms can be described as "azure, a wolf rampant gules" (blue, with a red wolf walking upright with its forepaws extended") and also has red squares in the top corners and a red line across the bottom. The red-on-blue design violates the rule of tincture and is most likely not a genuine historical coat of arms.
Monroe doesn't seem to fear the Grimms as much as other wesen. He starts the relationship with Nick by attacking him, and then asking him in for a beer. When Monroe was a kid he heard scary stories about Grimms and all the ways they have killed and dismembered his ancestors. In particular he has heard many frightening things about Marie Kessler, Nick's aunt, who seems to have a bloody reputation in the supernatural creature world. His great-grandma's head was cut off and placed on a lamppost by Marie. His grandfather was mutilated by the Grimms and his farm was burned down. He does admit that his grandfather may have deserved the treatment for some of the things he had done. Monroe also mentions that his parents are alive, and are apparantly highly traditional Blutbads, for that reason Monroe didn't want them visting, while Nick was living with him. He tells Marie that if they knew he was this close to a Grimm without avenging his family he would not be invited to any more Thanksgivings. ("Bears Will Be Bears")
On his mother's side, he states he has a great-uncle Olaf, who was a newsreel cameraman in 1920's Berlin. When Olaf died, his camera equipment was transferred to Monroe's mother. Monroe mentions to Nick that he'd be rummaging through his attic for the camera equipment later, implying that his mother passed the equipment down to him.
Monroe has a cousin Nadler, who lives in Antwerp. Nadler called Monroe and informed him that a Grimm had been killed near where he lived.
Monroe mentions that after a couple of beers his grandfather would start speaking High German. Whether this grandfather is the one who'd been mutilated by the Grimms is unknown.
