After a night spent out clubbing, Tim returns to the flat wearing the wrong coat, and convinces Lee to help him return it to its owner.
Lee's past catches up with him when a young woman appears on his doorstep and asks for a cup of sugar.
Lee promises to stop treating Lucy's flat as if he owns it - but not before he has hired it out to a film director.
Lucy and Tim are distraught. Their parents' 30 year marriage is at an end and their father has moved out of the family home - and into Lee's bedroom.
