I'd caution you not to let him into your inner circle. He advises some of the law enforcement personnel here - Miss Corwin in particular.
I was hesitant about him, at first, but he always stressed that we were family, and sometimes he was very good company. I wanted to overlook his absurd attachment to muggle ways because of it. Do you think that was very weak of me?
Regardless, he wants nothing more to do with me, so that is an end to it. At least now I needn't worry about him upsetting Arcturus with his muggle nonsense.
