I have googled it but what's the background to the main characters in DCI Banks - I've only just started watching it and there's been some sort of party (at the boss' house) and a baby was introduced to everyone).
Annie, with the baby, was a close colleague of Banks, hence the crack about He's got your ears, though there was never any explicit relationship between them, in the books nor the TV version. The other woman, with the sons, isn't in the books so I can't halp.
