Romance classically has tragic underpinnings 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.

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.

As frustrating as it gets, at times, and as frustrating as it is, at times, I don't think I've ever considered doing something else, or not wanted to do it anymore. To me, it's just the greatest job. It's a good fit for who I am and what I want to be.

Even then, I didn't quite know what to make of it [captain Kirk death]. I was mystified by why I was doing it, why I was so driven to do it, and why it was affecting me like it was. I still don't know what it means. It's a strange singular experience. I don't even know anyone to talk to about it because I don't know anyone who's had that experience.

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.

After you get a season under your belt, you learn a lot of lessons. It's a much bigger challenge, logistically, in terms of production.
