- The scene where Nick talks with Roddy at the end of "Danse Macabre". It's a fairly quiet moment, but Roddy's unspoken acknowledgement that Nick honestly doesn't mean to harm him and that his anger-driven plan of revenge could have ended up a lot worse is rather touching.
- Monroe's inspirational speech to Roddy, about recognizing the beauty of his talent, and the way their lives "collide in the most bizarre ways," finishing up with giving him his card and a promise that Roddy can call him if he needs anything. Awesome to see Monroe's softer side.
- Nick and Monroe's interaction with Holly Clark, the feral Blutbad girl.
- Holly and her mother's reunion after nine years apart.
- Renard being protective of both Hank and Nick when the Ogre starts coming after them.
- From "Organ Grinders", Nick and Juliet taking two homeless kids out to dinner.
- Juliette and Monroe’s official introduction after Monroe had complained that he was rescuing a girl he hadn’t met.
- Nick, who has so far tried hard to stick to Lawful Good, protecting the woman who tried to kill his aunt and rarely doing more than stretch the truth to hide the supernatural elements of his investigation that he can't explain, drives Ian Harmon to the bus station and gives him back his forged documents rather than arrest him for a justified but cold-blooded murder he just saw him commit—because it's the only way to protect his friends Rosalee and Monroe.
- Monroe and Rosalee rushing towards each other after there was a fight. "ARE YOU OKAY ?".
- Monroe stepping in a fight to defend Nick, and Rosalee interposing for everyone's sake despite being much weaker than both fighters.
- Rosalee gives Mama Burkhardt a farewell hug. And yes, that was a smile.
- Mama Burkhardt and Monroe giving each other an approving eye waggle in mutual respect for each other's toughness and dedication to Nick. Considering who they are and the sort of culture they grew up on, it's saying something.
- Hank having the mental fortitude to handle finding out 1) that he's not crazy and 2) that his goddaughter and one of his best friends are Wesen. He doesn't let the revelation change his relationship with them.
- Most of the dates at the beginning of "Over My Dead Body" could count. It's very sweet to see Nick and Juliette get a fresh start after every thing that's happened, and Monroe and Rosalee were just too cute being their adorkable selves. Then Angelina arrives, and it all goes to Hell...
- As Hank and Nick go through Aunt Marie's trailer, Hank asks Nick how he can possibly sleep with all the horror inside. Nick's answer: "I got you watching my back."
- Bud hugging Nick and Hank after they rescue him from immanent death
- Hank gets one with the victim in "To Protect And Serve Man". After saving the man from execution, they share a moment over the fact that they both know about Wesen. As with Hank, the man becomes much calmer over the fact that he and another share the same secret knowledge. That, as Hank put it, he wasn't crazy.
- Monroe comforting Juliette after Nick finds out she kissed someone else in "Season Of The Hexenbiest".
- Similarly, Monroe letting Nick move in with him after Nick's split with Juliette.
- Monroe and Rosalee's reunion. He's all flustered and dithering about how to greet her, she simply walks up to him and kisses him in a very comfortable way, as if they've been an established couple for a long time.
- Seeing Hank, Nick, Rosalee and Monroe all eating together as they discuss the whole Renard situation in "Mr. Sandman". Looks like the Grimm Gang is starting to become like a family.
- In a Black Comedy kind of way: Catherine has just left the spice shop after treating Rosalee quite rudely, including complaints about the prices. Unknown to her, Monroe was in the back, out of sight.
Monroe: Cheapskate has no idea how close she came to getting her throat ripped out.Rosalee: That's so sweet!
- In the same vein as the above, "One Angry Fuchsbau" has a Ziegevolk lawyer who has just lost a court case because of Rosalee, only to run into her later in the spice shop, as well as Monroe. The Ziegevolk tries to attack her, so what does Monroe do? He picks the lawyer up and throws him into the spice cabinet. Nick actually had to pull Monroe off of him to make him stop, so it goes without saying that you do not mess with Rosalee around him.
- Juliette's flashback to when her and Nick first moved in together.
- In "Endangered," Juliette's flashback to when she and Nick first said "I love you" at a party. When she comes out of the memory, we see her staring at the photo of them kissing under the mistletoe with the first real smile we've seen on her in ages.
- Monroe, Rosalee, Renard, and Juliette working together to save Nick after he falls under the control of a Musai.
- Especially Juliette, because she had just awakened her memories of the night when Nick tried to explain everything, making her think he was crazy. Instead of going back to thinking he had gone off the deep end, though, her experiences during her amnesia have given her perspective that allows her to accept what he was trying to tell her back then.
- Juliette successfully convincing Rosalee, Bud and Monroe to woge for her because she not only wants to remember Nick but she wants to understand him too.
- Season 3 premier. Monroe is very insistent that they have to get Nick back. The power of the royals be damned, that's his friend!
- Monroe asking Rosalee to move in with him, and telling her he loves her.....awwwww.
- When Juliette questions Nick about "M", they calmly sit down and have a discussion, like two adults. It shows how they have come back together as a couple for good.
- Monroe decks out his house for Christmas in order to surprise Rosalee, a task which requires Juliette's help to be completed by the time she comes home. After he finds out that Rosalee doesn't have the fondest memories of Christmas, he packs everything away overnight for her sake. Then, when Rosalee decides that she wants to move on with her life with Monroe, she redecorates the entire house - also overnight.
- When Juliette reveals that she knows her friend Alicia is a fuchsbau, things get tense between them. When Juliette casually mentions that Nick's a Grimm, Alicia makes a run for it. Then they bond over the collective ass-kicking of Alicia's abusive husband Joe. Alicia shows Juliette her Game Face and they hug it out. Awww...
- Monroe proposing marriage to Rosalee...with a cuckoo clock. It's just so...Monroe.
- After their bigotry and closed mindedness caused a rift between them, Monroe's parents try not to lose their son. His mother tries to get to know Rosalee. His father tries to just leave him. But, when his wife refuses to abandon their son, he tries to change Monroe's mind. It goes rather poorly. When he finds out that Monroe helped Nick hunt Wesen, he is one step from walking out forever. Monroe says that he's going to help Nick take out a Wildesheer, one of the most dangerous Wesen in existence. His father is clearly worried. He just looks lost when he leaves. He follows them and, when the fight starts to go poorly, jumps in to save them.
- Juliette visiting Wu in the mental hospital and helping him get over the trauma of seeing the Aswang.
- Alexander, Monroe and Rosalee all Woging at the funeral as a show of respect for the mummified Anubis, who was tortured to death by the Ancient Egyptians so that the pharaohs could "become Gods" in the afterlife.
- Nick taking Trubel to the trailer, showing her that she's not crazy and he's just like her.
- Nick's overall interactions with her as they grow closer. They almost look like a brother and his little sister.
- Monroe's father goes out of his way to make amends over his initial reaction to Rosalee and Nick and winds up dropping $7200 on a new wedding dress for Rosalee when her sister destroys their grandmother's dress.
- On a related note, Monroe very graciously lets DeEtta off the hook for destroying the dress by telling her that he and Rosalee hated it.
- Season 4 premier, Monroe and Rosalee skip their honeymoon in order to make sure Nick and Juliet are ok after the events of the last season's finale.
- After Nick and Juliette find out Adalind disguised herself as Juliette and had sex with him he feels so guilty he offers to sleep on the couch. Juliette's reaction? She takes him by the hand and leads him upstairs.
Juliette: We are not doing that again...
- Renard's mother, Elizabeth, saves him when he is on the precipice of death.
- Later, while Renard's asleep and in pain from his injuries, Elizabeth smooths his hair back like a mother does, and he smiles a little before he even wakes up, like any kid would react to his mom's touch when he's not feeling well. It's unexpectedly adorable.
- In "Dyin' On A Prayer", the fact that the Fisher family banded together to deal with the abusive step-father and step-uncle.
- Mom: She attacks her ex-husband with a poker to save her son, and manages to get him to safety (even though she suffers a concussion in the process).
- Uncle: Summons a golem to take revenge on the abusive men (although he's horrified when he realizes the golem has murdered them both.
- David: Bonds with Trubel and uses her teachings to defeat the golem and overcome his fears.
- The best part? The abusive ex-husband and his brother were Wesen. The Uncle/Mother/David? Completely human.
- All of Trubel's intereations with David.
- The thing that finally convinces Juliette to go along with Nick's re-empowerment is the fact that Monroe and Rosalee need help from a Grimm.
- While sleeping together while Juliette is morphed into Adalind is something neither Nick or Juliette is particularly happy about, their comforting words to each other manages to be sweet in an awkward way.
- In "Highway of Tears," Trubel hugs Juliette and Nick, as if they were her older siblings or parents.
- When Nick meets with a pacifistic Wesen family in "The Grimm Who Stole Christmas," the mother only has a brief and mild Oh Crap! before calming down. A scene later, three pairs of parents are placing faith in Nick, a hunter of their kind, to help their sons. It's a nice change from the usual ass-kicking response.
- A Coycotl woman has a similar reaction in "Chupacabra." Apparently, rumours of a benevolent Grimm are going around.
- Monroe and Rosalee thanking Nick, Hank, Juliette, Renard and Wu for risking their lives to save the former from death.
- An odd but cute moment in the last scene of "Heartbreaker." Bella drinks a concoction Rosalee made that will hopefully cancel out her involuntary discharge of lethal toxin, not only so she can stop killing, but because she wants the chance to experience being in love, even knowing there might be side effects since the concoction is completely untested. In a flash forward to a few weeks afterward, we see Bella with some kind of green skin condition, a side effect of the potion. But she's on a date with a guy covered in tattoos and piercings, who thinks she's a knockout.
- In "Iron Hans," despite the tension of the moment, Adalind gently urging Nick to feel their baby kicking. It's only after this that he decides to trust her and take her to Rosalee to help find a cure for Juliette.
- And in the following episode, she tells her deceased mother that she loves her and promises to raise her children "the right way." In fact, she seems to have become a nicer person in general since siding with Nick.
- In the season premiere, the birth of Adalind's son helps reinforce the new alliance between her and Nick & co. First, she names her son in honor of Nick's mother, and he, in turn, agrees to put aside their differences to raise him. Then, Monroe and Rosalee pitch in to help her settle in to Nick's home. After all that, they're all noticeably more comfortable around each other.
- Nick's and Trubel's interactions in The Rat King and Wesen Nacht; Nick is just so relieved to find her.
- In "Eve of Destruction," Trubel hops on her motorcycle, goes to Meisner and confronts him about what happened to Juliette now Eve. She comes back to the loft with a meeting for Nick so he could get answers and closure.
- Adalind confesses her feelings for Nick the night before he departs for Germany to find the hidden Grimm treasure. They have certainly come a long way from being mortal enemies.
- In "Skin Deep", Nick is playing with Kelly, both father and son smiling. Its the happiest we've seen Nick all season.
- Adalind finally reunites with Diana in "Good to the Bone".
- Although it seems rather out-of-place during the events of the season finale, the reveal that Rosalee is pregnant still garners a heart-tugging reaction from Monroe.
- In the premiere, Nick manages to find Adalind, and the first thing they do upon reuniting is passionately kiss each other. Adalind then takes Nick upstairs to their son, where the two savor the moment, like a family.
