This Is Us Season 5 Episode 15 is about Kevin letting go of the past to marry Madison.

Kevin is having a bachelor party at the cabin while Madison has a bachelorette party with Kate, Rebecca, and Beth. Kevin's party plans are initially ruined by a rainstorm, so the guys go inside to watch Jerry McGuire, causing Nicky to make a cynical comment about how Kevin IS Jerry, marrying the mother of his children when he doesn't love her but wants to do the right thing.

Meanwhile, at Madison's bachelorette party, Kate has hired a nude model who turns out to be an ex of Madison's who once ghosted her. While the women are painting the model, Madison reveals that Kevin had no interest in her until she became pregnant, leading Kate to wonder if Madison is truly happy.

And in the past storyline, Rebecca takes the kids to the cabin for the first time since Jack's death, where Randall and Beth agonize over how to handle being apart if Beth takes a summer internship in Boston and Kevin and Sophie fight over whether they can handle a long distance relationship.
