My friend asked me recently, "Do you find it weird that you are now the property of other people's imaginations?" I hadn't thought about that before, this passionate following, with fan fiction and artwork. At first it felt like an invasion of privacy, but then I realized it's nice that the character can be shared.

There is one living organism, called a tardigrade, that has survived the five great mass extinctions on Earth, and it can survive in vacuums in space and boiling hot water and freezing subzero temperatures.

I studied classical percussion for ten years. At one point I was thinking about going to the Sydney Conservatorium of Music, but then I realized it's actually not what I wanted to do.

I would love to do something with space. I'm obsessed with it.

When you're placed in a world where survival is the main focus, a lot of that other stuff, like wrongdoings in the past, become obsolete. You have to focus on the here and now. Yes, there is tension between the two of them.

I often think about how, if we were all placed in an apocalyptic situation, you'd realize quickly how stupid, petty things just don't matter anymore. Who you love is who you love, and it doesn't matter. Survival is your primary focus.

I think the toughest thing for me to figure out, as an actor, was how to translate all those layers that are in there and that history that the writers have done such a great job at forming.
