"Oh no," Hermione says, one hand quickly rising to her chest. She knows that wedding ceremonies and receptions do have a tendency to go on for a while, and for someone who isn't fond of crowds, and who isn't personally acquainted with either bride or groom besides, Hermione can only imagine how troublesome it must feel. She turns a slightly regretful gaze towards the young man. "I'm sorry to hear that! Please, please let him know that if he needs to leave early, he should feel free. Neither Ron nor myself would mind. More than anything, I want to make sure that people here are having a good time. And I understand how crowds can be overwhelming, besides."
