I Love You Day is here again and the whole Bates crew gathers for an elaborate "Chivalry" themed party with food, games and amazing costumes. Before the big event, Kelly Jo and the girls decorate for the party and get caught up on all the biggest family news like Carlin and Evan's wedding plans, Trace's romantic prospect, and the exciting news that Michaella and Brandon might be moving to Tennessee! Meanwhile, the Bates boys hit the slopes for the day in a "Battle of the Brothers" as snowboarder Lawson and skier Nathan compete for the fastest speeds. Later, the love fest continues when Josie and Kelton invite their family over for a gender reveal party. When the balloon pops, will it be baby boy or baby girl!?
