Ben and I have talked about the scope for Crichton and Aeryn getting domesticated, and the fact that she's always going to do it differently. We'd really turn it on its head.

What I liked about Aeryn was that her attitude was always very black and white. Aeryn would be in a very interesting territory now, because she's mellowed. But I love the fact that in the miniseries, with a line like "shooting makes me feel better", she's not going away in a hurry.

She responded to her child immediately - I love the fact that she's always stroking the baby's head in the background, and there's never a moment where she's not having serious physical contact with the child. I read an article recently where Meryl Streep was saying, you are the mother that you're going to be before you have the child, and I like the fact that Aeryn probably vowed, since she didn't have contact with her parents, that she's going to try and be the opposite and be the greatest mum that she could be.

Because the scope of the miniseries was massive, I was worried that now Aeryn had served her purpose, all she'd have to do was pop out a baby and the fans would be happy and Crichton would have his child. Next generation, here we come.

So it was very important to try and work out what Aeryn's attitude was, and not ground her too much in a domestic, earth-type scenario. Giving birth - let's be classically Aeryn about this, let's find ways to make sure her spirit isn't dwindling.

David Kemper created such a fascinating character that a lot of the new writers would say "I want to do an episode for Aeryn."
