With the lease up for renewal, George announces he is raising the rent so the tenants look around for another person to share costs. Jo puts forward James, a friend of a friend, but Robin champions Linda, who, unknown to Jo and Chrissy, he already knows - very well. In the event Linda and James decide to have their own flat share whilst Mildred, vexed that George has taught her bird to swear, kicks the offending budgie out. He can be the other flat-sharer and the rent will stay the same.
