Thats one of the more interesting psychological subplots tho, how he was brought up to be a killer, how he choses his victims, and how he is perhaps, perhaps not, normalising and finding his 'real' self. Harry's code is becoming less important. His relationship with Rita (always want to call her Beryl, dont know why!) starts as a fake to make him seem normal and is now really important to him. His development is really interesting. I think he is becoming more moral, then he does something so awful in such a cold and detatched way. Great stuff! I think its an intelligent program.
I understand why you didnt follow the series tho, the first episode is a shock, and I wonder if I am now becoming desensitised (sp?) to the killing. Those opening credits are so impressive.
