Both Mark and Jeremy have trouble with Alan Johnson as he assigns Mark to oversee a difficult presentation to the JLB board, while the offer of a real life "indecent proposal" involving girlfriend Big Suze proves too tempting for Jeremy to resist.

Mark is fed up with Jeremy and decides to evict him, installing an Australian woman named Saz in his place, hoping she'll become his new girlfriend so he can rub Sophie's nose in it at his forthcoming Birthday party. Jeremy is desperate for money and having exhausted the sperm bank, he resorts to stealing Johnson's credit card.

Mark's promotion bolsters his confidence, he's getting closer to Dobby through a shared love of fantasy role-playing game and Sophie's ready to annul their marriage - but a drunken one night stand has life changing consequences. Jeremy decides that his life is going nowhere and joins a cult, which gives him a new outlook on life completely. With Mark and Jeremy's lives moving in different directions is this really the end of the El Dude brothers?

Jeremy starts working at JLB Credit, however the entire UK division of the company gets shut down by the German head office the same day. Mark forms a group to protest against the firings but really wants to impress Dobby.

Mark invites Dobby to a party at his flat, then has to work out how he'll actually organise it. Meanwhile things have gotten a bit frosty between Jez and Elena but he reckons he knows to handle it so she'll come running back to him.

After Gail's surprise proposal to Elena, they are soon to have a civil partnership, but Jez won't give up that easily. Sophie is also due to give birth and wants Mark to pass his driving test, unfortunately he gets a bad driving instructor.

After discovering Dobby has a boyfriend, Mark and Gerard become allies in a "Dobby club". Super Hans joins a band and Jez is excluded, but tries to get the upper hand through his new job with a record label owned by Zahra's boyfriend Ben.

It's New Year's Eve. Mark wants to find Dobby and sort things out between them, Jeremy just wants to have a good time. However newly-single Zahra has invited Jeremy to move in with her.

A month has passed. Dobby has still not said that she will move in with Mark and Jeremy has not said he will move out. Mark invites Dobby round to share a pizza and watch 'The Apprentice' but unfortunately Gerrard, her other admirer, dies of the flu that evening and Dobby feels guilty for not being with him. Jeremy decides to undergo therapy which, after an inauspicious start, he loves. Mark goes for a job with a bathroom fittings company but the final interview clashes with Gerrard's funeral so he has to make a brief oration before leaving. At the wake Mark again asks Dobby to move in with him but she says there is no need as she is now an independent woman, thanks to the money left her by Gerrard.
