While the Aimes play host to Ron's office Halloween party, Rachel confesses to Ron that she thinks she may be pregnant. Before she can get up the nerve to take a home pregnancy test, Emma - after eavesdropping on her parents - informs Bruce, Francine and Darby that her family is expecting a new addition... but the announcement may be premature. Also, Ron gives Bruce a lesson in humility when they go to a drug store to purchase feminine products for Rachel.
