Kill off a character -- a major character -- right before our eyes? Oh, yes. On this show, with these writers, I think that's a very real possibility. Actually, it's been done before. A few years ago the Law & Order writers killed off an ADA in an automobile accident barely off camera (we heard the crash, just didn't see the impact); then the camera cut back to the intersection and we saw the wreckage and knew she was inside one of the cars. That episode is still hard to watch, even now.
