When Tim gets two tickets to the GRAMMY Awards from his rock star patient, Charlie Puth, he brings Samantha to the show to impress her. Also, Matt and Colleen realize how out of control planning a wedding can get when they meet with their offbeat wedding planner, Ned Gawler; John and Joan join Facebook so they can stay connected to the kids; and Heather manically tries to save Sophia's beloved goldfish from dying.

In the season finale, when Colleen and Matt miss all the flights to Mexico for their wedding, they question if they will ever get married. Also, Greg and Jen get into trouble when they share a cookie with a fellow plane passenger who has a severe allergic reaction to it, Joan and John rush their dog to the vet after he swallows Matt's wedding ring, and the Hughes family moves into Tyler and Clementine's tiny house when a fire breaksout in their kitchen.
