- This sweet little exchange from "Dead End Street" reveals George's love for animals:
Dr. Ogden: But the death of a cat would be a sufficient motive for murder?
Constable Crabtree: Yes! As a pet owner, Doctor, I'll vote for that.
- In the same episode we see Murdoch go to great lengths to understand and find a way to communicate with Lydia, an autistic woman who does not speak and who he believes witnessed a murder. While most other people are ready to write her off as insane, Murdoch has no trouble believing in Lydia's intelligence in spite of her lack of speech and difficulty interacting with people, and he makes the effort to look at the world the way that Lydia might see it. Lydia's brother and caretaker, Bert, also clearly accepts and understands her in a way that very few other people would; as Murdoch learns from one of the neighbors, Bert was once married, but the marriage broke up when his wife demanded that he have Lydia institutionalized and Bert refused.
- When Murdoch goes to have a big show down with the Big Bad of season 3, he has a protective shield against the deadly rays. George worries about the horse because it's not protected. D'aw! Murdoch promises to take care of it. D'aww! And he does make sure the horse survives. D'awwww!
- Crabtree reading to Higgins by his hospital bed in "War on Terror," and then again when he uses his good nature and sweetness to gather information to solve the case.
- George and Emily's kiss in "Murdoch and the Cloud of Doom." There's even romantic music in the background.
- From Journey to the Centre of Toronto, an archaeologist named Elva Gordon has had her funding revoked due to her unconventional theory about the existence of mole people. Eventually, she's arrested on suspicion of diamond theft. Except, it turns out she was innocent- a geologist named Herbert has been in love with her for years, and he stole the diamonds in order to fuel a machine he'd built for her (though, he did take one piece simply to give her as a gift). After breaking her out of jail, he offers to go exploring underneath the earth with her via the machine, and she happily accepts. Ignoring the thievery and destruction of property aspects, it's a beautiful story. Everyone thinks they're both odd, but Elva's the one who suffers the most. Yet, Herbert truly admires and respects her for who she is, and instead of it being about trying to gain her romantic affections, he does all this because he knows what will make her happy: Having an opportunity to continue exploring her theory.
- As of episode 9x10, Julia and William are parents! They adopted the baby left orphaned after his criminal parents died.
- During Murdoch's "journey to the future" in "20th Century Murdoch," he sees that he has a son with Julia, which is heartwarming all on its own. However the boy mentions "Uncle George." The entire thing is actually a hallucination induced by a seizure and is at least partially informed by Murdoch's own thoughts. It's a subtle moment that betrays how highly he thinks of Crabtree.
- From "Hell to Pay" and "Up From Ashes":
- George and Nina's reconciliation, as he comes to realize that she was the right one all along.
- Murdoch seeing for the first time that George survived the ambush at the end of "Hell to Pay." Brackenreid and Julia both note with amusement he's more overjoyed to see George alive than he was to learn they were safe.
- Watts expressing his regard for Jackson, with whom he worked closely on one long-running investigation, as both a man and a copper after the latter's death.
- Higgins, in shock from seeing his two colleagues die in front of him, still has faith in Murdoch's innocence he helped smuggle Julia to the cell to see him
