We feel sympathy for Arthur because he feels uncomfortable within his own family and he feels as he can't share what he is going through and what he has gone through,with them. We know this because he feels un-belonging in his family which is shown to us when he says 'I began to feel set apart from them all, an outsider to their circle'. Hill makes us feel sympathy for him through the use of 1st person narrative by expressing a feeling we have all felt before. The language she uses suggests that Arthur doesn't belong with them and that he belongs somewhere else, she did this with use of the word 'outsider'. Another reason we feel sympathy for Arthur is because of all the pain he has to go to to finally be free of what happened in the past and that reliving what happened is 'the most agonising task' which suggests that this is the first grief he has ever experience and that he doesn't know how to handle what he is going through
A fear is created for Arthur by his blindness to the warnings given to him and the truths that have been told to him. This is done when he ignores the suspicious behaviour of everyone he mentions mrs Drablow too for example
