You know I usually HATE when unnecessary things that never happened in books get added to movies, and I might be alone in this. BUT, I absolutely ADORED this scene.
It’s like, those of us who read the books knew how close Hermione and Harry were. And we could read and understand their emotions in the period after Ron abandoned them. But that’s hard to communicate in a movie without doing a weird out of place monologue. I just thought this was perfect.
