In the scene, Hermione and Ron dance together. It's not in the book. The movie people added it. It's a very nice addition. Still...if they had time for that, why couldn't they included the Dursley stuff? I felt a bit robbed that they left it out.
But I'm not too robbed, because someone made this very creative clever video. The voices aren't the best, but the acting itself isn't so bad.
