I didn't mean that he locked himself away, I was just saying that if he spent all of his time online and stayed away from everyone else, his brother might not have seen the site.
He would have had to have been really upset over all of this, usually people don't take that much time just to find out the author of a book when he could probably looked up Greg's phone number on the internet or something.
Of course I considered that his brother had books, what i was asking was "how would he have known that Greg had any authority on bionicle other than writing the books?"; for all he knows, Greg could have been told what to write by the story by the bionicle story team, and just had to write it in a way that kids could understand it.
As a side note, why are you so intent on defending someone that pmed Greg just to yell at him for what some bullies did to his brother at school, Aanchira?
