Neville smiled and let Luna take control of the place settings. To be honest, it didn't really matter to him where they sat. The hardest part for him with being around Snape was that he always had to watch his tongue. Several times he'd called the boy Snape - instead of Severus like he was trying to remind himself to do.
Sitting down next to Luna, he closed his eyes for just a second and reminded himself, once more, to be careful. He didn't want to mess up and say something about the future or anything like that. He and Snape had been getting along rather well - much better then he'd thought that they would. After all, he was still terrified of him. And he never knew what to say around him. So, he sat there, quietly, waiting to see what the people around him would say.
