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.

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

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.

Maintaining a secret identity is a mighty ask, and there's every chance that Tim's cover is going to be blown when he's forced to take Marcus to work with him. Also, there's extra cringe in this week's therapy session when Owen leads Philip and Judith in an elaborate role-play exercise.
