Now that Riley knows the truth about Margot, she decides to find her biological father and uses her parents' high school yearbook as a guide. With a little help from Ben, Riley narrows down the possible candidates to David, the easygoing pastry chef, and Mark, the high-powered attorney. But despite some initial deception and old teenage rivalries resurfacing, Riley finally learns her father's identity. Meanwhile, Tucker is not happy about his parents' divorce and realizes the source of their problems is that Marshall is too uptight. But when Danny asks his mom to help Mr. Dobbs loosen up, Bonnie takes the challenge to a whole new level.

Riley gives Ben and Danny the time capsules they all made in the fifth grade, forcing everyone to reflect on where they are in their lives and what they really want. Although Bonnie advises Riley to figure out who she is today, she is not happy when Riley and Tucker crash her dance classes with Vladimir. Ben realizes that he's never actually accomplished anything and decides to finish at least one thing he started, so he asks Georgie out on a date. However, she is more interested in Danny, which prompts Ben to reach out to his brother's ex-girlfriend Amy in the hopes of sparking a romantic reunion.
