Depends on the story and setting. The Mc isn't exactly a person who experienced much of the world. He spent most of his life sick in bed, unable to do anything. He4 is placed in a setting where surrounded by experienced adults who like Lady Hale who can talk circles around him. I don't think there's anything wrong with him, but I do think he can grow from his current experiences and become more bold and dominant.
It's not like he has to get ripped or anything, he can just use his brain and play his cards to his chest.
