I haven't really interacted with the human much, I'm afraid. It's a pity, because I would like very much to get a good look at some of those devices he carries. They're almost as far from Forerunner tech as it's possible to get while still being made by humans... beyond that, though, he seems interesting enough. I know he tries to look after his people, and that he has a sense of responsibility. I think, if we were in my galaxy, the Sangheili would approve of him.
