Three married couples are competing in mixed doubles curling at the Milan Cortina Winter Olympics, using their relationships as a competitive advantage. Norway's Kristin Skaslien and Magnus Nedregotten utilize a post-match ritual called the 'hot wash' to manage emotions. Other couples, like Canada's Jocelyn Peterman and Brett Gallant, and Switzerland's Yannick and Briar Schwaller-Hürlimann, also navigate the challenges of competition while maintaining family ties. The dynamics of sibling teams, like Sweden's Rasmus and Isabella Wranå, are highlighted as easier to coach compared to married couples.
