It would be odd to sit at a table other than the Gryffindor table. In all his time in school (both of them) he'd always sat there. However, it wouldn't do to try to force people to sit somewhere other than they were comfortable. And he knew that Luna would be most comfortable there - although one of the things that he liked about her was that she was comfortable anywhere - and so he nodded. "That's fine." He smiled, looking down at Luna. He knew how excited she was - it'd be nice for her to have a friend (a real one) other than him. Not that he minded spending all his time with her. He rather liked it.
