Problems

( Bracken has a variety of issues he deals with on a daily basis. )

It's important to note that despite these problems, it doesn't mean that he (or people like him in reality) don't have intelligence. He doesn't want to be talked down to or treated like a child. He wants to help and feel useful.
He will rise or fall depending on the people around him. At home, where he has found his place among friends, he does almost anything that's asked of him to help out and is among the strongest players because of his willingness to do tedious tasks for hours on end. In particular, he does a lot of the 'farming' to bring other people items they want.
In a bad situation, it would be easy to leave him feeling frustrated, isolated and depressed.
In RP, I certainly don't demand either of these situations from other people. Characters can react ICly to him however they would react, and he will act ICly in turn. I only want players OOCly to understand where he's coming from.
