Out of all the housemates I think Christopher has had to put up with the worst in terms of persistent attacks to his self-esteem, from the way Pauline isolated him and broke his spirit, to Helen's constant digs that she doesn't value him as much as other people, and Mark saying that he wouldn't be close to him if Mathew was still here. And Christopher has just smiled/ laughed much of it off and not really played any sort of victim card or been acknowledged as a victim. But with all the comments about Helen being insecure and she lashing out it seems that the quieter characters get ignored, which really can't help a person's self worth if it's always the loudest people getting all the attention as if to say that their problems are more important than theirs.
