Who's Your Daddy?

Kate decides to take on a pro bono case against the advice of her father Jerry, when Aaron, a struggling musician, seeks their help in determining the paternity of his ex-girlfriend Marla's child after spotting her pushing a baby stroller less than a year after their break-up.

Meanwhile, a recently single Kate becomes angry with Laurel after she finds out that Laurel has been dating Michael ^the dreamy architect^ and David, the local peach vendor, simultaneously.

On top of all that, Kate is devastated when she receives a visit from long time friends Peter and Gabby who want her to handle their divorce. Kate has doubts about taking on the job, but when Jerry assigns a cynical Nick to assist her, Kate is thrilled with the outcome.
