The format was changed for this series, with the dual timelines and much of the flashbacks dropped for a more linear narrative. Moffat felt that the relationship had already been sufficiently established in the first series so there was little point returning to the start. Set two months after the end of series one, Mark meets Becky in a newsagent, where he is purchasing pornographic magazines. He discovers the location of Becky and Trevor's house and breaks in using Tracy's keys. However, he is forced to hide under the bed when Becky and Trevor return home. Listening to them having sex, he becomes optimistic when he thinks that Becky begins to shout his name ("M..."). The name turns out to be Michael (Tony Gardner), Becky's solicitor with whom she is now cheating on Trevor.
