Careful, even a mouse can bite back...
I am impelled not to squeak like a grateful and frightened mouse, but to roar....
A Mauzhertz summons up an unusual amount of courage and goes on a killing rampage.
Meanwhile, some other Wesen have a message for Monroe.
This episode provides examples of:
- Asshole Victim: All the victims were some kind of abusive bully. That's because when Martin encounters such people he starts seeing his bullying father, and kills them in a sort of panicked rage.
- Beethoven Was an Alien Spy: Monroe suggests that the mouse creatures are behind Disney - though he doesn't say the company name, he does his usual Take That! on the subject by bringing up "their cartoon thing". Or this could have been a more general reference to the common cartoon theme of mice outwitting and outfighting larger, stronger predatory antagonists.
- Fairy Tale: An aversion, since it's taken from John Steinbeck's book Of Mice and Men.
- Feuding Families: Variation. The snake creature suggests that they are natural predators/antagonists towards the mouse creature that also appears.
- Friendship Moment: When Monroe is beaten up for "messing with the status quo" by helping a Grimm, Nick says he won't ask Monroe for help again. Monroe declares that Nick can ask him for all the help Nick needs, and they toast the moment with a beer.Monroe: I've never been much of a status quo guy. And next time, we'll be ready for them.
- Mugging the Monster: Even those species that aren't gifted with physical capabilities or supernatural abilities tend to have quirks that make them hard to deal with. The mouse creature is shown crawling through small spaces far faster and better than a human could.
- Nice Job Fixing It, Villain: Monroe tries so hard to stay out of Nick's investigations... but it seems that he just can't. By attacking him, the Reapers basically reverse Monroe's stance on the matter instead of warning him off as they intended.
- No-Holds-Barred Beatdown: Monroe is lured away somewhere and jumped by an unknown group of Wesen, who leave him beaten unconscious in the street and paint a scythe symbol on his car.
- Raccoon Scare: Early in “Of Mouse and Man”, Juliette and Nick get out of the house to investigate strange noises. It’s a raccoon looking for its dinner in their trash can.Juliette: Don't arrest him! He's just hungry!
Nick: [...] I am not eating what he’s eating.
Juliette: Sure you are, you just got to it first. - Screw the Rules, I'm Doing What's Right!: Monroe is breaking all kinds of taboos by helping Nick, but he is not going to let that stop him from doing what he thinks is right. This point is made clear when he's ambushed by a group of creatures who beat him bloody and unconscious, then scrawl a Reaper scythe emblem on his car; Nick says he won't ask for any more help, but Monroe refuses to knuckle under to threats.
- Sanity Slippage: What happens to the murderer in this episode after his father dies. He sees his father's face whenever he encounters a bully and kills them with whatever's to hand.
