Mark and Sophie return to work, while Jeremy renews his acquaintance with the depraved Super Hans, in yet another filthy, funny episode.

Jeremy finally runs out of money and finds himself on a downward spiral of hunger, homelessness and criminality. Meanwhile Mark needs to find a girlfriend before his birthday party.

Mark gets into online gaming and live role play with Dobby and wonders whether she may be The One. Meanwhile, Mark and Sophie finally sort out their annulment. Jeremy joins a cult.

Newly promoted Mark decides to enjoy his additional power and wealth by splashing out on a boiler, a 'creamy elephant' sofa and by finding Jeremy a job in the office. Things are also looking promising for Mark in his pursuit of Dobby, the company IT girl. However, a routine fire drill puts his plans into total disarray.

Mark makes a final play for Dobby, the object of his desires. Meanwhile, Jeremy meets a new love, Russian émigré Elena. Both guys are determined to impress, but one of them is an expectant father. And when the pregnant Sophie spills the beans, both Mark and Jeremy's worlds change forever.

Jeremy realises that he's in love with Elena and decides to be generally less selfish to win her affection. He also thinks it might be a good idea to tell her he loves her, but Mark isn't so sure...

As a last desperate hurrah before the baby arrives, Mark and Jeremy decide to throw a party. Mark sees it as his final opportunity to reignite his relationship with Dobby, while Jeremy imagines it's a chance to make Elena insanely jealous. But as the evening proceeds, it all becomes a bit of an emotional roller-coaster.

Dobby, the object of Mark's desires, is now dating a graphic designer named Simon. Both Gerrard and Mark are determined to win her affections. Ben offers Jeremy the ideal job as head of development for his music web site.

Jeremy holds a book group at the flat in an effort to try and impress Zahra but apart from Mr Nice, Jeremy has never read a book. Mark is concerned by not being able to satisfy Dobby's sexual needs and decides to get some help for the problem.

Mark has invited his parents over for Christmas dinner. Everything has been planned down to the last detail but Jeremy has become over excited and Dobby and Super Hans show up as unexpected guests.

Mark is depressed about Dobby on New Year's Eve but Jeremy is determined that the 'El Dude Brothers' are going to have the best night ever.

Mark has asked Dobby to move in with him, and Jeremy is faced with the prospect of moving out to make way. But Jeremy has been dragging his heels and Mark is increasingly worried that Dobby will move in with his rival, Gerrard instead.

Mark gets a lucky break when his book, 'Business Secrets of the Pharaohs', is accepted by a 'publisher'. Jeremy, in an attempt to kick-start his career, enrols on a life-coaching course.

Simon, Dobby's ex-boyfriend, invites Mark, Dobby, Jeremy and Superhans to join him and his friends for a paintballing weekend. Mark is convinced that Simon is using the weekend as a cover to get back with Dobby, and Jeremy is convinced he can life coach Neil, Simon's best friend.

Jeremy, desperate to avoid living with Superhans, sparks up an old relationship with Mark's siser Sara, and moves in with her and her five-year-old son, Joshy. Mark, meanwhile, in an attempt to deal with a damp patch on his bedroom wall, launches a campaign to be elected chairman of the freehold committee of Apollo House.

Jeremy finally agrees to leave the flat and move in with Super Hans. Mark employs a decorator, Andy, to repaint the kitchen, and Jeremy helps out by giving him free 'life-coaching' advice. Meanwhile, Mark enrolls on a business studies evening course and meets Stephanie an attractive older woman.

Dobby is offered a job in New York by ex-boyfriend Simon. Uncertain about the offer, Dobby suggests that she and Mark spend a weekend in the country. The perfect time, as far as Jeremy is concerned, to get a few things off his chest.

Mark and Jeremy are reunited in the flat, Super Hans prepares for his wedding day, putting Mark under pressure as his best man. But there's a perk - Dobby will be there.
