In "Parental Guidance," Ben takes Emma to his old pediatrician for a check-up and must admit he hasn't had a physical in years. When the doctor insists Ben has an exam and finds something of concern, Ben has a bit of a panic attack about his future and worries about who will take care of Emma. He flashes forward through Emma's life as she's raised by Bonnie, Tucker and Danny and is horrified by what he imagines. Ben knows Riley is the best choice for Emma, but she has serious doubts about her maternal abilities. Bonnie has lunch with Brad, mistakenly believing that he is his twin brother, Tad. After their talk, Bonnie realizes she's still in love with Brad and wants him back. But when Brad reveals his true identity, Bonnie can't believe he's still so deceitful and never wants to see him again. Meanwhile, a flash mob yields a very surprising twist.
