Mark and Sophie both return to work after their disastrous wedding day, with Mark determined to "Mandleson" her in proving who should get all the blame. His only sympathizer is new IT girl Dobby, who's looking for something far more adventurous than a USB stick in the stationary cupboard. Jeremy and Super Hans rope Sophie's nephew Barney into their band when they realize he's actually got some musical talent but their gig is destined to end in disaster when Super Hans goes too far with seeing how far they can push Barney.

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.

Jeremy starts getting to know gorgeous new neighbour Elena and Mark invites Dobby round to the flat one evening. But they are about to find out who the father of Sophie's baby really is.

Jeremy thinks he has fallen in love with Elena and tries to win her heart. Mark tries to get a job as a guide for London history walks.

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 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.

In his efforts to impress the pretentious Zahra Jeremy decides to host a book club for her and her friends in his flat though disaster strikes when it becomes apparent that he has never read a book - apart from 'Mr Nice'. Mark meanwhile battles with Kenneth in order to gain the favours of Dobby but finds that he might need some help after all to satisfy her.

Mark has his family over to the flat for Christmas dinner, as well as Dobby, who he is finally going out with, except he hasn't told his parents yet.

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.

Now a big name in bathroom sales, though annoyed that Dobby has a new job in I.T., Mark writes a book, entitled 'Business Secrets of the Pharaohs' and even finds a publisher in Greg, who meets him at a refreshment stand. However Mark is told he must foot half the publishing costs. Jeremy decides to be a life coach and goes on a week's course but is the only candidate to fail - largely because he made such bizarre sexual demands of course leader Celia - though he does work out that Mark has been conned by Greg.

Simon,Dobby's ex-boyfriend,asks Mark,Jeremy and Super Hans to join him on the paint-balling day Dobby has bought as his birthday present. Simon puts Dobby and himself into the opposing team to Mark and Jeremy,leading Mark to believe it is all a ploy to win Dobby back. Dobby and Jeremy bond over a joint but Mark is stuck in a bunker with a stoned Hans. When Hans makes a break for it and aims his paint-gun at Dobby Jeremy gallantly steps into the line of fire to take one for her.

Jeremy agrees to move out of the flat and share with Super Hans but Dobby would prefer to go inter-railing across Europe than move in with Mark. To make things worse for Mark not only has Hans been promoted above him at work, making him Mark's boss but Jeremy has arranged for the unstable Big Mad Andy to decorate the flat - largely so that Jeremy can sign him up for life skills coaching. Mark finds solace in an MBA evening class, meeting the elegant Stephanie and Jeremy, strangely in love with Dobby, urges him to pursue her but Mark cops out when he gets a call from Jeremy requiring his help to calm down Big Mad Andy.

Jeremy is moving again, to stay with Mark's sister Sarah and her five-year old son Joshy, for whom he is something of a toy. Despite Jeremy having taken all his chairs Mark hosts the residents association for the flat block and is elected chairman - though he does use the funds for his own repairs. On the down side he is less successful as a taps salesman despite Jeremy's efforts to help and Dobby tells him she will not be moving in with him. He will not be alone though, for, having had enough of Sarah and surviving an uncomfortable night at Big Mad Andy's, Jeremy returns to the fold.

Mark is hoping Dobby will move in with him so Jeremy has to move back with Super Hans,who stays up all night and keeps snakes. Dobby has a job offer in New York from ex-boyfriend Simon so Mark decides he and Dobby should have a picnic in the country where he can declare his feelings for her. Sadly for him Jeremy,who is also in love with Dobby,turns up as well,leading Dobby to believe that they are gay as they are so inseparable. The two men start to fight over Dobby only to discover she has gone. Later she texts to say she is heading for New York.

Mark is uncertain about being best man at Super Hans' wedding, until he discovers Dobby is invited. Meanwhile, Jeremy's life coaching career is taking off but leads to a surprising encounter.

Mark and Sophie both return to work after their disastrous wedding day, with Mark determined to "Mandleson" her in proving who should get all the blame. His only sympathizer is new IT girl Dobby, who's looking for something far more adventurous than a USB stick in the stationary cupboard.
