Hannah: (Referring to "Noah and Saskia") A lot of teenagers do hide behind the Internet, it gives them a way to paint themselves up to be someone completely different.
Hannah: I was watching TV and I asked Mum 'Is that real?' She told me it was, and I love imaginary games and pretending things so I just knew straight away [acting] was what I wanted to do.
