When Kirk dies it was very emotional and very strange, in the moment and all the way through the process. I'd read it in the script and I'd always be struck by what I'd just done and what we were doing, and that this was my childhood hero and I was writing his death.

There are definitely times when the outside eye can shine a light on something you weren't aware of. They're usually exposing a flaw or a problem. Sometimes they're saying, "Hey, this doesn't really work. Have you seen this?" And then, you go, "Oh, I didn't really see that. You're right, that doesn't work." If they're good, they shine a light on issues that you're blind to because you're too close to it.

When I finally got my break in TV, as a staff writer, I always wanted to be at the top of that pyramid. I always wanted to make the decisions. I always wanted to be the one that was saying, "This is what the show is, and this is what the show is not. This is where we're going. It's going to be this kind of series." It was just something I always had my eye on, when I started in the business.

It was difficult, and yet I was very eager to do it. It was a really odd thing. I really wanted to do that story. I really wanted to write the death of Captain Kirk. I really wanted to do it in the movie.

I think people are screw-ups, and even our greatest heroes are deeply flawed human beings. People make bad decisions for all the wrong reasons, and then somehow they'll do the right thing, and then somehow they'll save somebody, or they'll be compassionate. Horrible people can do wonderful things, and wonderful people can do horrible things.

There were a lot of lessons of production to be learned. On the page, the biggest thing you learn on any TV show is how to write to your cast. You write the show at the beginning with certain voices in your head and you have a way that you think the characters will be, and then you have an actor go out there, and you start watching dailies and episodes. Then, you start realizing what they can do and what they can't do, what they're good at and what they're not so good at, how they say things and what fits in their mouth, and you start tailoring the voice of the show to your cast.

I'm always tempted in the back of my mind to continue to write things in the Star Trek universe, in the novels or the comics, just because I don't get to play in that universe and I don't get to hang out with those characters any more. You spend hours upon hours of your life, day after day sitting in writers' rooms, talking about these people and these situations, and it becomes very real to you. They're friends of yours, in a lot of ways.
