Harry was the favorite kid and he wasn’t even an official part of the family
Because Molly knows exactly how the Dursleys treat him. There’s no way Ron wouldn’t tell her. And Molly Weasley is a Mother. She gets a capital M because she is goddamn phenomenal at what she does. When she hears Harry Potter is on the train to Hogwarts in Book 1, her reaction isn’t to be starstruck. It’s to say “that poor dear had to come here all on his own.” Molly Weasley loves harder than anyone. She loves like it’s her sole reason for being. And when she hears there’s a poor boy who has never known love his whole life… how could she not?
In Year One Molly Weasley knit Harry a Weasley family sweater and made him homemade chocolate so he would have something to open on Christmas DON’T TOUCH ME
could I also just add that kids from abusive households tend to assume that yelling is directed at them and/or it heralds something bad for them so she’s making extra sure that he knows that this is not his fault and she’s not actually mad at him.
Also look at his reaction, he tenses and looks to Ron and the Twins for support.
also in the book he was legitimately frightened until she said that

"Well, then, I am confused…I’m afraid I don’t quite understand how you can give Mr. Potter false hope that —" "False hope?" repeated Professor McGonagall, still refusing to look round at Professor Umbridge. “He has achieved high marks in all his Defense Against the Dark Arts tests —" "I am terribly sorry to have to contradict you, Minerva, but as you will see from my note, Harry has been achieving very poor results in his classes with me —" "I should have made my meaning plainer," said Professor McGonagall, turning at last to look Umbridge directly in the eyes. “He has achieved high marks in all Defense Against the Dark Arts tests set by a competent teacher."
And under here, Hedwig”—Harry pulled open a door under the stairs—“is where I used to sleep; You never knew me then— Blimey, it’s small, I’d forgotten… .” Harry looked around at the stacked shoes and umbrellas, remembering how he used to wake every morning looking up at the underside of the staircase, which was more often than not adorned with a spider or two. Those had been the days before he had known anything about his true identity; before he had found out how his parents had died or why such strange things often happened around him. But Harry could still remember the dreams that had dogged him, even in those days: confused dreams involving flashes of green light and once—Uncle Vernon had nearly crashed the car when Harry had recounted it—a flying motorbike..
"Luna had decorated her bedroom ceiling with five beautifully painted faces: Harry, Ron, Hermione, Ginny, and Neville. They were not moving as the portraits at Hogwarts moved, but there was a certain magic about them all the same; Harry thought they breathed. What appeared to be fine golden chains wove around the pictures, linking them together, but after examining them for a minute or so, Harry realized that the chains were actually one word, repeated a thousand times in golden ink: friends…friends…friends…friends… Harry felt a great rush of affection for Luna" — Harry Potter and the Deathly Hallows
"But she didn’t look like Hermione at all. She had done something with her hair; it was no longer bushy but sleek and shiny, and twisted up into an elegant knot at the back of her head. She was wearing robes made of a floaty, periwinkle-blue material…” - Ch23 | THE YULE BALL
THIS! Also I wish Rowling would have explored Hermione’s motivations more, because damn, these tags did a better job at explaining her motivations than the actual books. I mean, seriously, we get to know all about Ron, get to learn all his deepest fears and his greatest motivations, get to meet each member of his family, get to see where he lives, get to know him outside the context of being one of Harry’s best friends… but Hermione? Well, we don’t even get to know half of that.
Hermione is one of my favorite characters, but we don’t get to know Hermione like we do Ron. In fact, this can be said of most of the women in the series when you think about it.
