Dynamite Doc or Christmas Dad?

What does Dusty really want for Christmas? Extract from the Diary of Dusty McPherson, aged 10 - "I've never had a proper family Christmas. It's always just been me and my mum Jess. But now I've met my cool Uncle Ben. He's a doctor - just like my mum. I didn't know him until recently, but now I'm starting to know what it's like to have a dad around. Uncle Ben makes Mum smile, and I even caught them kissing. But when I told her she blushed! As soon as Christmas is over we're going home. But if I'm a really good boy maybe Uncle Ben might want to come too?"
