The family celebrates five years together in the upcoming episode of Freeform's "Switched at Birth" season 5.

Titled "Long Live Love," next week's emotional 90-minute spring finale will take viewers on a trip down memory lane. According to the official synopsis, the episode kicks off with Kathryn (Lea Thompson) becoming nostalgic when she realizes that five years has passed since the switch was discovered and the two families began living under one roof. While looking through old photos, Kathryn discovers a long buried family secret that goes all the way back to the switch that could change everything.

Bay (Vanessa Marano) is praised for her tattoo work in a magazine spread, but her efforts to prove herself as a true artist to John (D.W. Moffett) begins to threaten their relationship. Daphne (Katie Leclerc) competes against Mingo (Adam Hagenbuch) for a sports medicine internship, while Toby (Lucas Grabeel) meets a woman who makes a huge impact in his life. Amelia (guest star Lauren Potter from "Glee"), a young woman with Down syndrome, helps change Toby's views about his son's future. Travis (Ryan Lane), Emmett (Sean Berdy) and Melody (Marlee Matlin) make huge decisions about their lives, and Regina (Constance Marie) gives love another chance.

Looking back at the show's five seasons, series creator Lizzy Weiss says a lot has changed for the main characters in the story. "John and Kathryn are fluent in both sign language and deaf culture. Kathryn considers Regina — once a stranger she was deeply suspicious of — to be her best friend," Weiss told Entertainment Weekly. "[Toby is] married, with a child of his own. Regina [has] two co-parents and a life partner. And the girls, Daphne and Bay, who were once deeply envious of each other for inhabiting the life they felt they were supposed to have, end the show as sisters, and soulmates."

The "Switched at Birth" season 5 finale airs on Tuesday, April 11, at 9 p.m. EDT on Freeform.
