Hermione

Ron Weasley, a young boy with red hair in a school uniform, reacts with a wide-eyed, open-mouthed expression of surprise or shock in a dimly lit classroom. The scene cuts to Hermione Granger, a girl with brown hair in a school uniform, who looks down with a pensive expression before looking up and opening her mouth as if to speak or yawn, while Ron looks on. The sequence then cuts to a small white dog holding a bunch of colorful balloons, including one with "Happy Birthday" written on it, as it walks through a doorway. The final shot returns to Ron, who maintains his surprised expression.
