Also, Max and Randy continue to text each other, but when she runs out of sexy messages to send him, Oleg offers to be her ghost writer.

Oleg and Sophie’s plan to have Max and Caroline as Barbara’s godparents is derailed when Oleg’s domineering mother, Olga, arrives from the Ukraine for the baby’s baptism and fires Max and Caroline from their godparent duties.

Also, Max rushes to Randy’s side when she hears he’s in the hospital in New York City, and Sophie joins a mommy group that cares more about partying than baby talk.

Caroline is excited to go out on her first date with Bobby, but she has nervous jitters when she realizes Max will be alone and in charge of the dessert bar for the first time. Also, Sophie and Oleg decide to mix things up and go out on a date instead of staying in.
