During the deactivation of Vanessa, a sexbot. Dorian quotes John from an early conversation, telling her that she will being going to a 'better place' and that he will 'remember her'. She smiles at him the entire time.
Episode 3 - Are You Receiving?
After both detectives complete their mission, John quips back to an earlier moment they had in the car were he tricked Dorian into heating up his coffee.
Dorian: Thank you, for what you did back there. John: Don't mention it. Besides, no one messes with my coffee warmer.
When Dorian expresses his fear of death, John doesn't dismiss it. Dorian is obviously touched by this. Compare this to the fact that John pushed his MX partner out of a moving car onto the highway without a second thought.
Dorian is touched; but this extends back to before the fight. John had actually expressed concern for Dorian going in alone, both knowing there’s a high chance Dorian could be damaged beyond repair. Dorian rationalizes it with “You can’t [come with me]. It’s what I was designed to do.” At first, it seems like they’re talking about how Dorian gets up (climbing several stories up the elevator shaft, among other things). Only later when you see Dorian jumping in front of the bullets and even crawling towards his gun, do you realize what he meant e.g he was meant to be a combat robot who could die so his human partner could live.

A quick moment, but touching nonetheless; Rudy calling Dorian 'my friend.' After Dorian is shut down by John for using the same term in a previous episode, it's heartwarming to see Rudy, at least, not treat him any differently.
Strangely, this is made more touching because it happens in a casual conversation; no attention is brought to it, and Rudy doesn't even realize he's said it, but it shows that he considers Dorian his friend, and therefore no hesitation using it as a term of endearment, android or not.
Rudy may not have realized he said it, but Dorian sure seemed to, judging by the sudden cut back to him.
Episode 6 - Arrhythmia
Dorian comes face to face with another decommissioned DRN model who is now a maintenance worker. Dorian has a heart to heart with John who is a bit irritated to take this other DRN for a ride along.
Dorian: When I was decommissioned, the second before it happened, I just kept thinking... “I really hope there's someone there to wake me up again.” — And then... you woke me up. It was you. You were that person for me, John. John: Well, we all make mistakes. The request is granted.
At the end of the episode there's a sad moment when the DRN has to be returned to the hospital and have his memory wiped. But Dorian lets him keep the memory of the little boy whose life he saved when he was a cop.

Episode 13 - Straw Man
Dorian passes his review with flying colors because of the, quote, "glowing references" from all his co-workers, especially Detective Kennex, who apparently told the board that Dorian is the reason he still wants to be a cop.
Detective Paul giving the homeless guy extra cash. His act of kindness probably ended up saving the guy's life, too.
In the future when you're listed as a missing person they send out robots that do not stop until they find you it's bittersweet that the technology to fake the death is becoming more and more common place. mixing a bit with tearjerker.
