Tim attempts to fine-tune his computer hacking skills at work, and later ends up putting them to good use by changing Marcus's school grades.

Tim wants to join Marcus's book club. The Examiner shows off his unique lie-detecting skills.

Tim is asking for trouble when he falls for a woman in the Witness Protection Programme, and Marcus learns how to ride a bike.

The Examiner is on star-spotting duties and casts Tim and Caitlin in a recruitment video. It seems like a perfectly good idea until the pair let their disguised identities get the better of them.

Tim is given extra incentive to rekindle his romance with Caitlin after finding himself on an assassin's hit list. Marcus, meanwhile, has been biding his time and is in prime position to humiliate rival Nick at Justine's dinner party.

Tim's spy senses are put to the test after he strikes a dodgy deal with The Examiner. Marcus gets a little bit of power and enjoys it.

Tensions simmer at school when new boy Nick stands against Marcus for school president. Tim tries to help Marcus but, given previous form, is more likely to hinder the campaign. Operation Sabotage is in full swing back at MI5 as Tim offers Caitlin and her presumed-dead but now actually very much alive fiancé Portis some rather dubious relationship advice. New counsellor Owen makes an impression too, taking a particular shine to Judith.

Marcus's hopes of organising the Summer Ball are dashed when the dreaded Mrs Godfrey usurps Philip as the school headteacher. Meanwhile, struggling to find a date, Tim tries to improve his luck with the ladies. Maybe he should take a leaf out of Bond's book.

After Judith receives a blow to the head she wakes up believing that she's still married to Tim. Poor Philip is understandably devastated, but on hand to pick up the pieces is Chris, who believes the best course of action is to reintroduce him to the dating scene right away.

In an hour long Christmas special, the magic of Christmas has long been lost on Marcus and, when his party plans force the other kids to go on strike, he must make alternative arrangements. Meanwhile, 'tis not the season to be jolly if you're Portis. The agent's thoughts turn to revenge after he finds out about Tim and Caitlin having feelings for one another.
