Bluth has delivered a perfect, beautiful take on this scene and its placement in the show, so I'll leave the stage for this one to him and, instead, want to refer to a snapshot of this passage in the books, which adds a meaningfully affecting layer to this moment and its importance to an aspect of Daenerys' inner life that the show has sadly never bothered to truly transfer into the show despite it being an essential pain of hers:
Dany looked at Missandei. “What are they shouting?”
“It is Ghiscari, the old pure tongue. It means ‘Mother.’”
Dany felt a lightness in her chest. I will never bear a living child, she remembered. Her hand trembled as she raised it. Perhaps she smiled. She must have, because the man grinned and shouted again, and others took up the cry. “Mhysa!” they called. “Mhysa! MHYSA!” They were all smiling at her, reaching for her, kneeling before her. “Maela,” some called her, while others cried “Aelalla” or “Qathei” or “Tato,” but whatever the tongue it all meant the same thing. Mother. They are calling me Mother.”

Game of Trivia: Welp, it's sad this didn't end up higher, especially as atonement for this last seaon but to come to the point, this was floating around in the Top 20 for quite a while thanks to bluth (SORRY fellow Katy Perry stan) but got bumped down later on because only the first submissions voted for it but at least they were all committed enough to Daenerys to write something up:
Ryan: Yes, it's definitely a white saviour-y moment, but WHO THE FUCK CARES WHEN IT'S SO MOVING AND BEAUTIFUL. Again, another moment as to why The Mad Queen turn makes no sense. Dany is a queen of the PEOPLE and understands what freedom represents.
Ridley: I can guarantee that this scene is especially loved as much by me because of the music that accompanies it. Was also really nice to have something empowering happen right after the Red Wedding.
Dalty: Mhysa! White savior or not, I don't give a shit, great moment visually and beautiful moment for Daenerys as she saved those who were once like her. But now this is also used a moment to show how she was secretly Hitler so whatever. I'll always remember her this way.
Bluth: It’s weird because i never thought that much about this scene until after the show ended. on youtube i watched the loot train attack dozens of times, daenerys getting the unsullied many more, but after game of thrones finished i watched this scene again and something clicked that it’s the way i want to remember the show
the immersive nature of game of thrones has never been so much about the world-building than it is more so how palpable every action, reaction and consequence is. as a result, the viewers adopt a similar role to those who exist within westeros: we mourn over tragic deaths and fear for the lives of many we care about. it is also why the audience gravitates towards glimmers of hope much in the same way the people of westeros do - we all want to see a better world for those we care about.
daenerys is game of thrones’ version of gatsby’s green light, that little flicker from across the water that makes so many believe in something better than the horrifying, tragic world that exists today, even if we have to ignore the warning signs to do so. mhysa is so much more resonant as scene considering its place in the series. at the end of season three, the war of the five kings is over, house stark all but obliterated in a savage coup. yet, in some distant land across the narrow stretch of waves, there’s a dream of a new, better world. after the destruction of a family comes a new mother, hope in the face of tragedy. it’s that hope that makes people continue despite the atrocities around them, to believe that something is better on the horizon, and what compels viewers to keep watching five more seasons to see it all unravel again. but, just like the broken king said, “i only live in the past, now.”
