 After Jimmy s van and all its contents including his tools and his jacket with his keys in the pocket gets stolen, Diana insists they change all the locks. This leads to a stand off between Jimmy s laissez faire attitude and Diana s belief in direct action. In the heat of battle about whose house this is, Diana reminds Jimmy that since she and her husband gave Ann the deposit on for the house, the place is partly hers. Meanwhile, after prompting from Siobhan, Jimmy reluctantly agrees to take the big step of introducing her to Diana and the kids. When Diana responds to Jimmy "putting things off" by hiring a professional locksmith, Jimmy ultimately has to break into the house to claim it as his own. As a result, when Siobhan does meet Diana and the kids, it is in far from ideal circumstances.
