I don't know why he came. He didn't appear to be injured, but I was concerned for his well-being. After checking with a wildlife expert, I was advised to let him be. I was told it would be best to wait and see if his mother would come for him during the night. She must have done just that, because the next morning he was gone.
Perhaps he only stopped in to say hello. Maybe he wants to be a character in my next book. Whatever his reasons, I do hope he left behind some wisdom for me.
