- In "Fugue," Morse is so tired from having stayed up all night trying to crack the case that he can't drive. Thursday takes him home and sits him on his couch, steps out of the room for a bit, and returns to Morse, who's so exhausted that he's fallen asleep (with his wound apparently re-opening). And then Thursday drapes his coat over him.
- Thursday's speech at the end of "Fugue," telling Morse that he doesn't have to give up music just because the killer used his love of it against him.
- After eliminating the dangerous suspect in "Home," Thursday immediately running to Morse, who's been shot, and making sure that he's okay.
- Thursday spends the entirety of "Trove" fussing over Morse, who's just come off light duties after being shot. His worry over Morse's wellbeing manifests as helping him ease back into police work, reassuring him through his occasional bouts of PTSD, punching the shit out of some thugs who dared to harm him, and paying Morse's neighbor to keep an eye on him.
- Morse, knowing that he and Thursday are probably both going to die and both of them refusing to abandon the other, recites the final verse to "May" by A. E. Housman.Ensanguining the skies
How heavily it dies
Into the west away;
Past touch and sight and sound
Not further to be found,
How hopeless under ground
Falls the remorseful day.
- When Morse visits his family in "Home", the quite sweet brother-sister relationship between Morse and his half-sister, Joyce, is shown.
- There's an adorable scene where Morse is at a store for case and runs into Love Interest Monica while she's mattress shopping. What makes it heartwarming is: In the 1960s, most people wouldn't assume a white man and black woman were together, and if they did, they likely wouldn't be happy about it. However, a salesman wanders over, assumes they are (they haven't quite gotten to a stage where they are at this point), and his only reaction is to try to help them find what he believes they want and make a sale. He's cheerful, addresses them as 'Sir' and 'Madam', and encourages them to lie down together on the bed to properly test it out.
- Morse helps out Mrs. Thursday, when she is falsely accused of shoplifting. They share a pint at the pub, where she further invites him to a family event.
- A minor one: In one episode, Morse is talking to a prisoner about a former cellmate. The former cellmate either couldn't read or had trouble with it, and the prisoner says he read the newspaper to the former cellmate every day. What makes it so heartwarming is: They weren't particularly friends, the prisoner wasn't afraid of the former cellmate, and there's no indication the prisoner was getting anything in return for doing this. So, it was just a case of a prisoner being a decent man and doing a genuinely kind thing for another person.
