Josh realizes he has made a mistake when he hires his younger brother, Jake, to help Gabi with preparations for Elliot and Alan's wedding; Yolanda panics when she can't locate Elliot's wedding ring.

Gabi is excited when Jake buys her a food truck, then learns the problems that come with running such a business; a rabbi is reluctant to give Elliot and Alan his blessing; Sofia and Yolanda find romance at the wedding reception.

In "Young & Christmas," Gabi and Sofia aren't able to be with their families this holiday season, so they decide to volunteer at a local homeless shelter on Christmas Eve. Yolanda is missing her kids and decides to boycott the holiday, at least until Gabi encourages her to reach out to her estranged sister, Jolanda. As soon as the siblings reunite at Josh's loft, however, old grievances are aired, and the family get-together quickly goes from bad to worse. But when Gabi discovers Jolanda is keeping a big secret from Yolanda, will the sisters finally make amends, or is more trouble on the horizon? Elsewhere, Josh goes out of his way to cheer up a miserable Elliot, who is missing Alan, while Sofia wrestles with her conscience when a department store clerk (Mindy Sterling) makes an error in her favor.
