The Oliver of season one was at one end and then the Oliver beyond season two was at the other. It was very black and white: “I am willing to use lethal force” and, then, “I am not.” Obviously it doesn’t just come down to that, but at the end of season four we found a shade of grey. Oliver is very much in that spot still. He says to Thea in the premiere that he has to admit Malcolm Merlyn is right: If he is not willing to do whatever is necessary, then he should not be out there at all. I think that makes a more interesting character, because it’s more dynamic. There are more colors to it.
