In the midst of all this, Kate is also embroiled in a nasty divorce proceeding involving a businessman whose wife is claiming that the pre-nuptial agreement they signed is void because he slept with the ^hot nanny.^ Although it seems at first like a pretty straightforward case, Nick charms some very valuable information out of the nanny, giving Kate and Jerry some inside information

Meanwhile, Kate goes before Judge Blake, to try her case against reality TV producer Chuck Webb, whose completely manipulated show ""Honeymoon Hotel"" humiliated Kate's unwitting client Mia and led her to seek a divorce.
