I think you could perhaps get that someone may have helped him and looked after him in a way that he didn't need to be very independent, George is always helping him and telling him things they don't have.. This could be down to his mental health but also down to his childhood. Just what I got from it..hope it helped a little :)
If you have to write about this (never read this) but you could be broad with what you say. Use things such as the timeline of the story, the actions the characters do and the emotions they feel. Of these things are possible in real life then of course it's realistic.
