Grimm (season 5)

Trubel, Juliette, and the dismembered head of Nick's mother, Kelly, are hustled out of Nick's house by unknown assailants. Chavez and Nick meet at an arranged time in an unused warehouse. Chavez's mysterious caller is Meisner, who with the help of the Resistance helped Adalind escape from the Royals. Nick and Chavez are attacked by a group of Wesen and Chavez is killed. Before she dies, Chavez gives Trubel's dark knight chess piece to Nick. Agent Chavez's phone rings, Nick answers it and speaks to Meisner. He tells Nick to keep the phone. Nick goes to the hospital to visit Adalind and their newborn son. Adalind names the child Kelly, after Nick's mother.

Nick takes Adalind and baby Kelly home. Captain Renard assigns Hank a new partner, who is not hip to the whole Wesen thing. This complicates Hank's next case, which clearly involves a Wesen killer. Things get complicated when US Marshals get involved and the killer flees. With Hank and his partner in pursuit, it becomes evident that these killings are somehow related to a mysterious secret society.

Rosalee's life is in danger when a group of orphaned Wesen children — Peter, Lily, Big John, and Miguel — in need of a mother-figure to guide them, decide that Rosalee fits the bill. Nick and Hank find a vital clue in a fairly recent missing-person case. Nick decides to move out of his home to a safer location. Meanwhile, Renard is informed of the King's "accident" and that his daughter is safe with the Resistance. (A basis of Peter Pan & The Lost Boys).

While investigating an assassination attempt against nightclub owner Frankie Adkins, who was saved by a mysterious Wesen, Nick and Hank stumble onto the archaic Wesen tradition of Maagd Zoektocht, where a Weten Ogen (a lynx-like Wesen) pits three suitors against each other for the hand of a maiden. In this case, Daniel Troyer is making them fight for his daughter Emily's hand, and their first trial is to kill Frankie, whose henchmen had killed Troyer's son. After a second unsuccessful attempt on Frankie's life, the first suitor's mother points Frankie to Troyer. Frankie tries to kill Troyer, who's saved by the mysterious Wesen, Emily herself. Troyer explains to his daughter that the test was for her to prove she was worthy of succeeding him. Meanwhile, home life brings Nick and Adalind closer together, and Captain Renard is asked to support an old friend, Andrew Dixon, who's running for Mayor. In the closing scene, an injured Trubel, assumed to be dead, shows up at the door of Nick's new pad, and collapses in his arms.

Nick brings a wounded Trubel to the hospital. While in the waiting room, Nick finds three false IDs and a fingerprint-locked phone in Trubel's jacket. Trubel tells the nurse her name is "Lauren Cole." This matches the name on one of the IDs and the registration of a very expensive, weaponized motorcycle. The next day, Nick and Hank are called to investigate the murder of two Klaustreich. Selina, the girlfriend of one of the victims, mentions a dump where they went to hunt Reinigen (rat-like Wesen) for fun, and informs them of a third missing Klaustreich, Johnny. Monroe and Rosalee explain the legend of the Riesen-ratte, "the rat king", a creature that is formed when several Reinigen with similar DNA combine into one being. Everyone ends up at the dump, but not at the same time. Johnny and Selina are captured by the Reinigen. Nick, Hank, Monroe, and Rosalee confront the Reinigen who transform before their eyes into the Riesen-ratte. They manage to save Selina and stun the Riesen-ratte using power cables to shock the giant rat-king back into it's individual parts. Several dozen Reinigen lay on the ground, groaning in pain. Afterwards, Meisner, with Adalind's help, manages to convince Nick to trust him, and they run to the hospital, where they save Trubel from a group of Wesen chanting "Occultatum Libera." Meanwhile, Andrew Dixon keeps trying to get Captain Renard to publicly endorse his run for mayor, promising him the role of Chief of Police.

Trubel tells Nick about Hadrian's Wall, the resistance group Agent Chavez worked with and that she now works for. They are fighting an underground war against Black Claw, the organization coordinating the global Wesen uprising. Nick, Hank and Wu are called to investigate a case of vandalism, murder, and kidnapping. At the scene, they find another claw mark drawn on the wall. They suspect the victims are Wesen, which Monroe, Rosalee and Bud confirm. Monroe explains that many historical revolts were instigated by Wesen. The kidnapped victim, Xavier — a friend of Monroe and Rosalee — returns, claiming he escaped, and points them to a woman, Billy. Nick and Hank come clean to Renard about Chavez's death and her last message: "They're coming to Portland, it's war." After Nick, acting as a Grimm, threatens Billy, she leads Nick, Hank, Renard, and Monroe to the gang's location. Rosalee drives Xavier home and he confesses to her that he lied; Billy is leading them into an ambush. Rosalee warns Monroe, but it's too late and they get cornered into a room. Suddenly it is quiet, they hesitantly leave the room and find someone has killed all the attackers... someone who bears an uncanny resemblance to Juliette. Meanwhile, Renard publicly endorses Andrew Dixon for mayor.

After his "Juliette" sighting, Nick confronts Trubel for answers. She reveals Chavez knew that Juliette was a Hexenbiest and wanted to turn her into a weapon. But Trubel adds she wasn't sure if Juliette survived what Hadrian's Wall had in store for her. Feeling guilty, Trubel meets with Meisner in secret and gets him to agree to let Nick meet Juliette, at a time and place of his choosing. Meanwhile, Monroe, Rosalee, the captain and Hank interrogate Xavier, who reveals the Wesen gang had its sights set on Nick and Monroe. Xavier adds that any Wesen who doesn't join them in their mission will be killed. Hank and the captain bring Xavier to the precinct and throw him into a cell until he can be placed in protective custody. Their plan is foiled when Lucien, Black Claw's leader, sends a hitman to kill Xavier. The assassin poses as a drunk and gets thrown in a jail cell alongside Xavier. He woges and kills Xavier in plain sight. A cop witnesses the woge and shoots him dead before Nick, Hank, Wu and the captain can intervene. Monroe and Rosalee alert the Wesen Council, and Alexander informs them that an organization called Schwarzkralle (Black Claw) is behind the uprising, but that he cannot discuss it any further. Soon after, a Wesen Council member reveals himself to be part of Black Claw and guns down the majority of the Council during a meeting. Alexander, the only member to get away, calls Rosalee and breaks the troubling news. Nick finally comes face-to-face with Juliette at a restaurant, where she introduces herself as Eve. She dodges most of Nick's questions, but does admit to remembering everything. Suddenly, she gets up, woges and kills a man telekinetically. The target's bodyguards quickly pull their guns, forcing Nick to get involved and put them down. By the time the cops arrive, Nick has handled the situation — and Juliette/Eve is gone. Meisner phones Nick and explains the meeting was a setup: Hadrian's Wall needed Nick's help to take out an important Black Claw organizer. The meeting was a test and Nick passed.^[16]

Nick tells Wu, Hank, and Renard that the incident at the restaurant was a test. He also tells them about Meisner, who works with Eve and Trubel, and also worked with Agent Chavez. Meisner and Renard know each other through the Resistance. Meisner is now part of Hadrian's Wall. Nick and Hank investigate the death of tourists at Diamond Lake, home of the Diamond Lake Monster. The local bait shop is owned by the Dunbar brothers, Oliver and Wayne, who are 'Luisant-Pecheur' (otter-like Wesen). Meisner, with Trubel's help, tries to recruit Nick to Hadrian's Wall. At the Portland Command Center of Hadrian's Wall, Nick sees a map that shows Black Claw-affiliated Wesen uprisings around the world. The command center is funded by a branch of the Federal Government. Back at Diamond Lake, Sheriff Parcell tells Nick and Hank that the story about the lake monster is a myth like the Loch Ness Monster or Ogopogo. With Trubel's help, Nick and Hank look for the Diamond Lake Monster, who they suspect is a "Wasser Zahne". The Wasser Zahne turns out to be Logan Cobb, a man who has been working with the Dunbar brothers in keeping the myth of the lake monster alive for a share of the profits.

Nick and his team hunt for a Wesen serial-killer, a "Fuilcre", who uses an ancient barbarian Wesen water-rune/rain-crucifixion, ritual. Monroe goes undercover at a pep rally to help Nick investigate a lead. The rally is actually a recruiting tool for Black Claw. Eve and Trubel interrogate a Black Claw suspect; Eve uses a "See No Evil", Speak No Evil", Hear No Evil" technique. Adalind helps Nick solve his case when she tells him about an Aztec ceremony, Fire Drill, involving Orion's Belt — whenever it rose above the horizon, a man would be sacrificed on top of a pyramid. This information leads to the next ritualistic sacrificial site.

Leipzig, Germany; Monroe's uncle, Antiquariat "Antiquarische Buecher" owner and antique book dealer, Felix Dietrich receives a call from Andrea Stroh, an appraiser in Prague, Czechoslovakia. She wants him to appraise some books from the estate of Joseph Nebojsa. Felix recognizes the books were written by and for Grimms. He calls Monroe to see if Nick wants to buy the books. Two Anubis Wesen from Black Claw kill Andrea and Felix flees to Portland with one Grimm book to show Nick. His asking price for all the volumes is $100,000. Nick doesn't have the money, but he is desperate to get the books; he could recover what he lost when Juliette burnt Aunt Marie's trailer down last season. The two Anubis Wesen, now in Portland, kill Felix in his hotel room. Nick and Monore find a shipping slip in Felix's room and race to the address. There they encounter the two Anubis Wesen and Monroe, in a fit of rage, tears out their throats. Nick and Monroe find Felix's trunk and take it to the spice shop. In addition to detailed catalogs of Wesen, the books contain Grimm family trees, including Nick's ancestry. Monroe finds a secret compartment and using his watchmaker skills unlocks it. It contains three keys! Using these and the two Nick already has, they stamp together the five pieces of the Map of the Seven Knights, ancestors of the Grimm. It leads to a spot in the Schwarzwald (The Black Forest, Germany).

Nick, Hank, Wu, Monroe, Rosalee, and Trubel continue to search for clues in the Map of the Seven Knights. Nick has a flashback where his mom, Kelly, tells him about the legendary seven keys belonging to seven knights, ancestors to all Grimm. The knights fought for seven royal families in the Fourth Crusade. The seven keys together made a map showing where the knights hid the precious wealth they took from Constantinople when it was sacked and burnt by the Ottoman empire. Nick believes the treasure could be found. Trubel thinks they may have buried it in seven churches. Nick and Monroe travel to Germany on counterfeit passports, using Frederick Calvert (Rosalee's late brother) and Felix Dietrich as their aliases, to avoid detection from Black Claw. They travel to the church locations marked on the map, but find little that is old enough to be a possible location. Local Wesen become suspicious of their questioning. Nick and Monroe head out at night to a spot in the forest where they think an ancient church may have been. They discover chisel marks on old stones and end up falling into an old underground cavern.

Surviving their fall, Nick and Monroe find themselves in the catacombs of the ancient church they've been searching for. Eventually they find a small locked, brass chest. Meanwhile, local Wesen have been searching in the forest for Nick and Monroe; they are discovered as they emerge from the catacombs. Nick and Monroe narrowly escape, though Monroe is bitten in the process. Meanwhile, back in Portland, Andrew Dixon, a mayoral candidate supported by Renard, is killed by a Marwan assassin. While Adlind is visiting the spice shop, Rosalee's ex, Tony, shows up. He becomes violent when Rosalee asks him to leave. He also turns his anger toward Adalind; in her distress, her Hexenbiest powers return and Tony flees. Renard receives an "anonymous" tip from Black Claw as to the whereabouts of the Marwan, tracks him, and kills him during a fight. Unbeknownst to Renard, this foils the plan Hadrian's Wall had to use the Marwan as a source of information. Later at his apartment, Renard is confronted with a Black Claw plan to set him up as the new mayoral candidate; he is tempted by this position of power. Nick and Monroe arrive at the spice shop and proceed to open the chest with Rosalee, Hank, and Wu present. They find an old shard of wood wrapped in a cloth. While debating its nature, Monroe begins to get sicker from the now infected wound on his arm. Still holding the shard, Nick tries to help a stumbling Monroe up. The group is astonished when the wound on Monroe's arm begins to disappear, and they deduce that the shard has healing powers.

Benito is a Wesen called Vibora Dorada who owns a store called Benito's Masks. Some of the masks he makes are endowed with special powers. Goyo, a young ambitious ring wrestler comes to Benito asking for a new mask to help him win games. Benito tries to dissuade Goyo saying the price is too high, but Goyo convinces him he can handle it. Benito heads out that night and attacks a Wesen called Balam. He bites the victim's neck which paralyzes him with a neurotoxin so the Balam stays woged. He then surgically removes the skin of the wesen's face to make this special luchador mask. Nick and Hank get called to the scene to discover a man with a flayed face. Benito tells Goyo that he is only to wear the mask in the ring, nowhere else. Naturally, Goyo cannot resist the power of the mask and wears it in his apartment and out on the street. He encounters one of his opponents in an alley and kills him, unable to control himself. Nick and Hank visit the scene of the killing and have leads indicating both Goyo and Benito might be involved. Meanwhile, Goyo seeks the help of Benito to get the now unremoveable mask off. Nick, Hank, Monroe, and Rosalee enter Benito's Masks just a little late. Benito is already dead and Goyo is dying. Rosalee, chanting in Spanish, performs the "ceremonia de desgracias" (Misfortune Ceremony). Vibora Dorada is a Wesen version of Xipe Totec adapted by Serendia Priests and Serendio.

On the first night of the full moon, a young successful entrepreneur is driving on a deserted wooded road to visit his mother. His tire blows and his car, out of control, hits a tree. He must now walk the three miles to his mother's house. The next day, Nick and Hank responding to an injured man on the road, meet up with the driver of the car. Something doesn't seem right, so returning to the scene with Monroe (and his extraordinary Blutbad sense of smell), they find in the woods nearby, two hikers that have been brutally attacked by what seems like a Blutbad. In the course of their investigation, Monroe and Rosalee mention a disease, Lycanthropia that turns Blutbaden into uncontrollable beasts when there is a full moon. Nick, Hank and Wu suspect the young entrepreneur, hold him at the station to see whether he woges. It quickly becomes clear, the Lycanthrope is his mother. They race to her house, confront her, and try to sedate her in her Wesen form. She is accidentally killed, but not before Sgt. Wu is scratched on his left leg. Meanwhile, Adalind is offered an opportunity to reunite with her missing daughter, Diana. Eve discovers that Black Claw is actively recruiting Renard.

Nick, Hank, and Wu investigate the death of a woman who aged seventy years overnight only to learn they are dealing with a Wesen, operating as a photographer, who sucks youthfulness out of young people and regurgitates it as a goo. He sells this goo to a doctor operating a clinic that caters the youth-obsessed. The doctor has created a successful and expensive anti-aging cream, which unfortunately he, himself, has become hooked on. In addition to removing his wrinkles though, the dosages he is taking is also making him quite insane. Rosalee goes undercover to help expose the racket. Meanwhile, Eve devises a plan to go undercover as Renard to learn more about his involvement with Black Claw.

An evangelical preacher named Dwight Eleazer has a tent revival unlike any other when he uses his Wesen identity to gain more believers. Nick and Hank are called to the scene as things escalate when a group of "true believers" are hell bent on saving the preacher and his flock by any means necessary. Meanwhile, Capt. Renard takes further steps to gain power in local government. Elsewhere, Eve uses Adalind's ol' hat trick to gain more access to Black Claw.

When Brian Johnson's head is found under a bridge, Nick and Hank link it to a Japanese Wesen family whose son was previously killed by the victim. Adalind accepts a job at her old law firm while Monroe and Rosalee volunteer to explore the tunnels under Nick's place while she is at work. Meanwhile, Wu is still feeling the after-effects of the fight with the Lycanthrope, including strange dreams and intense headaches. Elsewhere, Rachel has a surprise for Renard, much to his joy.

Adalind and Nick enjoy an intimate moment. Hank runs into Zuri Ellis, his former therapist, and they have dinner. At the scene of a single car accident, the lone drunk driver is kidnapped only to be later repeatedly run over by his kidnapper. Once all the drunk's bones are broken, the kidnapper, a bird-like Wesen, uses his tongue-like appendage to dissolve and ingest the bones for later regurgitation to his sick parents. Nick, Hank, and Wu are called when the boneless body is discovered. Nick tells Adlind that Renard is working with Black Claw. Adalind wonders whether Renard will use their daughter, Diana, in his attempt to become mayor. Eve, who continues to monitor Adalind, learns about Diana. Nick, Hank, Monroe, and Wu set a trap using Monroe as bait to catch the bone-sucking killer. Wu, whose Lycanthrope symptoms have become worse, is triggered by the full moon and the sight of a stray dog, fully woges and chases the dog. He stumbles, gets a nasty cut on the head, and knocks himself unconscious. The bone-sucker is distracted from Monroe by the fresh scent of Wu's blood. He finds and starts to drag Wu away, but is thwarted by Nick and Hank. In his attempt to flee, the bone-sucker is hit by a truck and dies. Nick and Hank locate the parents and when given a few moments alone with their son at the morgue, they decide not to waste his bones. Meanwhile, Rosalee babysits Kelly so Adalind can meet clandestinely with Renard. But Renard knocks her out and takes her to an unknown location to reunite her with Diana.

When Sgt. Wu becomes involved in an altercation that results in the killing of a petty thief, he decides to go to the spice shop and figure out what is happening to him. Meanwhile, Meisner and Trubel go to Diana's safehouse only to learn that she was taken by Black Claw as leverage to convince Renard, Adalind and even Nick to join their cause. Not knowing what to do, Adalind takes Kelly and disappears, leaving Nick a note saying that she has to protect her children and Nick.

Distraught over Adalind and Kelly leaving, Nick tries to contact Hank then goes to Sean Renard's house, only to find it completely empty. Monroe and Rosalee manage to calm him down and they decide to inform Hadrian's Wall about what has happened. Renard calls Nick to meet him at the police station where he admits to having Adalind, Diana, and Kelly, as well as working with Black Claw, but insists that Nick should also join them. Meanwhile, Hank arrests Tony (Rosalee's ex) for breaking into Zuri's house, only to find out that they are both working for Black Claw. Nick decides to show Trubel what he found in Germany, just in case anything should happen to him. The episode ends with Renard being elected mayor, while Trubel and Eve start to interrogate Zuri.

After Renard is declared mayor, Hank is arrested when two bodies are found in his house. Nick realizes this was set up by Black Claw and with Monroe's help, he learns Hank's location from Tony. Nick, Trubel, and Eve go to rescue Hank, only to find out this was a trap to get them away from Hadrian's Wall's headquarters. They return but find everyone dead, including Meisner. Unable to control himself, Nick attacks Renard at the police station, and Renard has him arrested on assault.

Black Claw starts to make their move when they learn Nick is arrested after attacking Renard. Stuck in jail, Nick instructs Hank to gather Monroe, Rosalee, Trubel, and Eve at the loft. Wu later calls them when the station is suddenly bombarded with 911 calls, leaving it almost empty. Monroe and Rosalee return to the spice shop to hide the Grimm books and weapons while the others go to rescue Nick, but he was already taken. They manage to rescue Nick, but Eve is wounded after fighting Conrad Bonaparte. They all regroup at the loft where Nick tries to heal Eve with the Stick, but things get worse when Diana warns them that Bonaparte was able to learn their location. Nick stays behind to fight while the others escape through the tunnels. After Nick manages to kill all the attackers, Bonaparte and Renard appear to confront him. Just as Bonaparte begins to kill Nick, Diana—in retaliation for coercing Adalind to reveal Nick's location—takes control of Renard's body long enough to kill Bonaparte, leaving both Nick and Renard in shock.
