'The 100' has such ferociously passionate fans.

That doomsday idea is in everybody's subconscious.

My mom's a children's television writer, so I was involved and around from a very young age. When I was eight, I did my first film with Rachel Ward and Bryan Brown, who are a quite well-respected Australian producer-director duo, and that just changed my whole perspective on what I could do in life and be.

I must say, I always - from experience, when I watch TV shows and I see characters leave without a proper explanation or leave with not enough time, I get irritated. I like it when there's a clean-cut reason or a defining moment where they have to go. Whether that's death or not, I think that's subjective.

Once electricity and petrol and facilities and food stop, society stops. It's crazy.

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.
