Eh, I kept reading the story, if only (at first) to see Archer screwing Kerry over, so I had to agree with you that it was a powerful moment of the story. As I said, in this story I was rooting for Archer, so if something can make me go with Archer instead of just drop the story, it must be good. That doesn't mean I have to like it, though. Or, in this case, like Kerry.
And let's be serious, that person wasn't a danger to his family except in Kerry's eyes.
