Martin finally confronts Matthew about the possibility that he needs medical help for his agoraphobia. Matthew, however, has different plans - he's finally left the flat and joined the band upstairs.
Wednesday is a big day for all of the housemates - Martin has finally got a date, while Mandy's latest boyfriend is fighting in a boxing match. As for Matthew, it's a day to wax his board.
A day in the life of Matthew shows him playing rock music in the early hours of the morning, and re-enacting movies during the day, along with questionable activities in Mandy's bedroom. Martin looks for assurances that he's really okay.
Martin's announcement that he's planning to move on and leave the flat produces a series of downward events and disappointments for Matt. Meanwhile, Mandy is suffering from anxiety after a relationship threatens to turn serious.
All three of the housemates wake from dreams that go unfulfilled, including Martin on an erotic date with a colleague. Yet in their waking hours, Mandy pressuring Matt to go outside causes him to get paranoid and want them to move out.
Mandy has another new job, and Martin is preparing to celebrate his 23rd birthday. Both of them experience fantasies about their situation, only to find that the reality is far less appealing.
Martin is boring everyone by constantly talking about his sex life, while Mandy's vow of celibacy is under threat when she meets her new Italian teacher. Matt, meanwhile, has finally got a therapist - only without knowing.
Matt has taken to watching the neighbours passing by through a spyhole in the front door. His new habit leads to him sleeping with Laura, the married woman from upstairs, but causes him despair when Mandy and Martin don't believe him.
After bumping into Clare by chance, Martin discovers that she'd had his baby in secret. His resulting bitterness doesn't just affect himself - it causes him to tell Mandy's new boyfriend Archie that she's only interested in his money.
Mandy announces she's gone celibate, just at the time when Martin finally gets a girlfriend. For Matthew, life is no different - except his two flatmates seem to notice that he's somewhat changed.
