What is Stuart planning to do with his friends?

Stuart: Amy, so how’re you doing?
Amy: Oh, hi, Stuart. School is so crazy these days, and when I’m not at school, I’m at work.
Stuart: Hey, listen. I’m getting together with Sara and Paul tonight, and a few of our other friends are going to join us. Oh, and, well, we’re going out to eat and then catch a movie. Why don’t you come with us?
Amy: Hey, I’d love to, but I have to cram for a test tomorrow.
Stuart: Ah, come on. We’re planning on having dinner around 6: 30 and then seeing a movie at 7:30. We should be home by 10:30... 11:30 at the latest. Come on!
Amy: …I don’t think I’d better. I haven’t been feeling well lately.
Stuart: Yeah, because you study too much. And it’s Sara’s birthday, too. And we’re throwing her a small birthday party after the movie. Come on. Best friends always stick together.
Amy: Oh, OK.
Stuart: Great. I’ll pick you up at 6:00.
Amy: OK. See you then, but I have to be back by 10: 30.
Stuart: Ah, 10:30... Midnight. It’s all the same. See you at 6:00.
