Jeremy plans to throw a secret magic mushroom party in the flat, where he hopes to seduce his ex, Big Suze. But when Mark suddenly comes home from work with gastric flu, Jeremy's plans go to pieces.

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.
