The fifth and final series of The Sarah Jane Adventures concludes on CBBC next week with The Man Who Wasn’t There.

Sarah Jane, Luke and Sky attend a preview of the launch of the new Serfboard computer and immediately realise there’s something odd about its reclusive creator, Joseph Serf. While Sarah attempts to interview a man who doesn’t exist, her children find something dangerous lurking in the basement.

The Man Who Wasn’t There (Part 1) airs at 5.15pm on Monday 17th October on CBBC. In the meantime, here are ten teasing lines of dialogue from the episode…

» ‘What a clumsy clot you are, Miss Smith!’

» ‘When it comes to men, I prefer something I can grab hold of.’

» ‘I suppose we’re… sort of… brother and sister.’

» ‘I had to leave K-9 back at uni.’

» ‘How will you feel tonight when everyone’s walking down Bannerman Road, with their arms out, saying, “Serve the computer”?’

» ‘Believe me: if he says they’re fine, they’re fine.’

» ‘Sarah Jane, let me drink you in.’

» ‘You were already old-fashioned when I was new-fangled.’

» ‘Oi, Mr Smith – don’t be nasty.’

» ‘I’m delicate… in a very manly way.’
