Just caught up with this episode.
Words cannot describe the revulsion I feel for Hugo's parents. What a nasty pair- they have bred a monster who will be universally hated and never develop any meaningful relationships unless they do something NOW! Poor boy- nasty as he is I feel really sorry for him. His poor little brother too- and the both of them having such toxic parents. 
Even if, as some have suggested, he has aspergers (and I have to admit- the first ten seconds of film of Hugo made me think this) there is no reason for him not to have been taught manners and humility. I can't believe they let him be so rude. What on earth is he like at school? He must be a teacher's worst nightmare!
I just love Shrinidi- such a natural little girl with such a passion for literature- I love the way she chooses books based on their smell!
