Girlfriend? Not just friend?

‘… What would you say are the main differences?’
‘You’re funny, Marcus.’
‘I know. People keep telling me. I don’t care. I just want you to answer the question.’
‘OK. Do you want to touch her? That’s got to be the first thing.’

Marcus carried on blasting away at the monster on the screen, apparently oblivious to Will’s profundities.

‘I don’t know. I’m thinking about it. Go on.’
‘That’s it.’
‘That’s it? There’s only one difference?’
‘Yeah. Marcus. You have heard of sex, haven’t you? It’s kind of a big deal.’
‘I know, I’m not stupid. But I can’t believe there’s nothing more to it. Oh, piss.’

Marcus has lost another life.

”Cos I’m not sure if I want to touch Ellie or not. But I still know I want her to be my girlfriend.’
‘OK, so what things do you want to be different?’
‘I want to be with her more. I want to be with her all the time, instead of when I bump into her. And I want to get rid of (her friend) Zoe, even though I like Zoe, because I want Ellie to myself. And I want to tell her things first, before I tell anyone, even you or Mum. And I don’t want her to have another boyfriend. If I could have all those things, I wouldn’t mind if I touched her or not.’
