The big day has finally arrived for Teresa and Joe as they welcome their fourth bambino into the world. Meanwhile, Chris Manzo scores big when he gets an inside look into his dream business, and Jacqueline gets an inside look into her husband's secret safe. As the Brownstone prepares for a big night, Danielle gets an invitation she can't refuse, but makes sure to get "back-up" from an old friend before she RSVPs.
