Playing normal is hard especially playing normal that's not you. The biggest challenge in playing Alicia is trying to make a teenage girl seem fully formed and not the quintessential moody teenager with a quippy, sassy line here and there.

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 was on Instagram or something and I checked my tagged photos, and I realized that suddenly they were all LGBT artwork. I was like, Oh, my god! I had no idea. It was the first time I realized I was a figure for that community.

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.

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.

Everyone sort of feels alienated at that point, so it's hard to say whether I felt like that because everyone does or because I was so focused on acting [since the age of 8].

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

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.

To go from playing a character that was so self-assured, so mature beyond her years, and so kick-ass and ruthless to someone who's quite normal is interesting.

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 did go to a performing arts school, so that facilitated my creativity, though I ended up going in a more musical direction.

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.
