"Barney and Robin clear the floor at a wedding for an awesome dance number," executive producer and co-creator Craig Thomas told EW of the moment depicted above. But don't let this one moment of fun fool you, the more somber tone HIMYM struck last season will carry over in a big way. "You couldn't miss it in that longing look she gave Barney, who was looking at Nora [Nazanin Boniadi]," Thomas adds. "If there are fans of the Robin and Barney relationship in all of its weird complexities, they're going to be very excited about this season. We pick up on the fact that there are feelings again."
