My first role was an angel in the nursery nativity. I spotted my mum halfway through and shouted over someone else's lines to ask if she liked my costume. I've learnt not to do that now.

Me? An angel! Just ask my mum about that!

I've never loved a character as much as I do Niska. The way she's been written is so complex, with huge amounts of light and dark. It's a really satisfying challenge to play someone who is superhuman in their intelligence and physical ability but completely naive when it comes to certain aspects of life.

I literally can't get anywhere now without the map on my phone. I used to use an A-Z when I first came to London, and now I really struggle because there's no dot to show where I am. And I think that part of my brain doesn't work any more.

When I was little, I was actually really shy. I really enjoyed doing school plays, but I found the whole thing terrifying. I cried myself to sleep once because I thought my teacher was going to give me the lead role. I never imagined acting was a viable career.

A family is definitely in my future, but I have no idea when. I don't know how people fit it in with an acting career, but they do. Katherine Parkinson is a great example of that, so I'll have to ask her.
