Mitch and Cam's best gal pal, Sal, makes one of her notorious surprise drop-ins, but this time with big news - she's getting married... tomorrow! Cam and Mitch are the best men, but they can't help but question whether this party girl can really settle down, and they consider an intervention. Meanwhile, Gloria has trust issues with their new nanny, Claire has a rare bonding moment with Haley, and Phil helps Luke with a girl he likes.

Mitchell and Cameron are looking to assign legal guardians for Lily in case anything were to happen to them, and are secretly assessing their family members. But no one is blowing their socks off, as they witness Jay giving Manny a dose of tough love, Claire secretly taking Luke to a child psychologist to assess his development, and Haley and Alex getting into some delinquent activities at school.

Claire delicately helps Luke cope with the fact that his friend and their old neighbor, Walt, has passed. Phil takes Alex for some father-daughter bonding time, and Haley throws an unauthorized party. Meanwhile, Jay and Gloria go over to Mitch and Cam's to have dinner with Cam's father, Merle, who is in town visiting -- and awkwardness and tension seem to be the rule of the night.

A teenage girl is brought to the hospital with severely swollen appendages after a wild night out; as her condition worsens, the patient is unable to distinguish fact from fiction; the doctors attend a medical conference.

When Lilly can't afford the upcoming class trip to Washington D.C. Miley offers to pay but Lilly refuses. In an attempt to help, Miley suggests Lilly have a yard sale which raises just enough for her to go.
