Kate is trying to make Lee choose a career, but when she suggests clown classes, she ends up taking them herself with limited success. Meanwhile, Lee agrees to go on a date with Lucy Moss, a serious and earnest author whose book was published by Kate's company, in an attempt to show Kate his serious side. Tim uses Lee's absence to try to make things up with Kate.
Episode 2: Death
Tim's 94-year-old grandmother dies, and when Lee fails to pass this information on to Kate she accuses him of not being in touch with his emotions. He reluctantly agrees to see an expensive therapist who soon gets to the root of his problems - his unspoken feelings for Kate. Meanwhile, Kate comforts Tim, who sees fit to hit on her at his grandmother's funeral. Lee comes close to telling Kate how he feels, but instead uses the time to be with his friend.
Episode 3: Aussie
Kate wants to impress a visiting Australian friend called Ruth (played by Julia Morris). Ruth has always been successful, and the only advantage Kate has ever had is her long-term relationship with Tim - hence the fact she has never told Ruth that the two of them split up. Kate persuades Lee to pretend to be Tim while Ruth is staying, and things become a little too close for comfort when the pair are forced to share a bed. Tim is horrified by Lee pretending to be him (and all that it implies), and decides that he'll get his own back and stop being a "middle class ponce".
Episode 4: Stress
Lee is trying to teach Kate to drive, but her skills - or lack of them - is sending his stress levels through the roof. Kate leads him in a yoga session and, when he fails to take that seriously, sends him to have acupuncture. While Lee is otherwise occupied, Tim offers his services in teaching Kate how to drive. All seems to be going well until Lee opts for prescription tranquilisers and the three embark on a drive in the countryside. Guest starring Miranda Hart as the acupuncturist.
Episode 5: Kid
As a favour to two friends, Kate agrees to take care of their 14-year-old son, Nicky, for a few days while they attend a wedding in the Caribbean. She wants Lee to bond with Nicky, but Lee's efforts get him nowhere; he is even more dismayed when Nicky and Tim discover that they actually have a lot in common. While the boys are bonding, Kate tries to talk Nicky's Great Dane into becoming a vegetarian. Lee's attraction to Kate doesn't pass Nicky by, but he forgets his intentions to spill the beans when Lee allows Nicky's dog to stay in the flat, despite his serious allergy.
Episide 6: Caretaker
To prove a point to Kate, Lee finally gets a job, as caretaker in his block of flats, but the job comes with a bedsit so he moves out, much to Tim's delight. Kate and Lee soon both miss each other, and when Kate interviews a prospective new flatmate called Pete, Lee puts him off and then, despite his pride, gives up his new job and so he can move back in.
