Rob secretly asks Hector to teach him Spanish so that he can understand what Maggie's family is saying about him. Meanwhile, Fernando lies to Rosa about his diet and exercising.

Maggie and her parents use a cute baby to try to make Rob change his mind about not wanting children. Meanwhile, the family helps Fernando with a commercial for his car wash franchise.
