Don't say anything online that you wouldn't want your mother to read.

Oh, the cat I worked with on 'Game of Thrones' was so badly behaved! It would never do anything it was supposed to do. I was like, 'Get your game together, cat. You're so bad.'

I am someone who isn't always perfect.

No one teaches you how to be a famous person; no one teaches you how to be a role model. It's something you have to do on your own.

I didn't want to escape my life and become a big actress and live my dreams. That was never the way it was; it was just these amazing opportunities that happened.

Going out is the typical thing when you turn 18, but it's not really much fun when you have a recognisable face.

If you're having a down time at school and people are bullying you, they don't know you. They don't have the right to have an opinion on you.

I don't think Twitter is a platform to build your confidence on at all. Not at all.

I feel like a lot of people would quite easily stab you in the back once they get what they want. And you see that in people.

I know things aren't perfect for women in the U.K. and in America, but there are women in the rest of the world who have it far worse.

Turning 18 is a big deal.

People just get kicks out of making other people sad.

When you cross over on fandoms, people don't know what to do with themselves.

It's helpful to have a handbag that's a bit crazy, or shoes that have kiwis on them or something, because it distracts.

I can't ever see myself playing the romantic lead because that's not me; I'm not that girl.

In the U.K., we're surrounded by American accents. Anything we watch in television. We have 'How I Met Your Mother' and all these other shows here, so it's not something that's really alien to us.

I believe that breakfast is the most important meal of the day, if you don't have a good breakfast, then what are you going to do with the rest of your day. I get scared when I don't have a good breakfast!

I don't have to be making a lot of money or living in a fancy house.

I've had a fast track to who I want to be. I know all of my friends are struggling to what to pick in college, and I've been given a fast pass to kick start my future.

I'm so excited to be working on 'Doctor Who,' as it's such a big and important part of British culture.

I'd much rather be liked because people realize that I'm standing up for myself.

I don't wanna be liked just because I'm pretty.

When you're filming, it's very different from what you see on screen.

I think a lot of people on Twitter say, 'Oh you're really cute. I want to adopt you,' and things like that, yeah.
