Shedding for the Wedding

This week the five remaining couples choose invitations and table settings with the help of wedding coordinator Brian Worley, and to mix things up, trainers Jennifer Cohen and Nicky Holender take the couples to a pole dancing class. Meanwhile, one couple has a heart-to-heart about their need to step it up in the competition, and for the first time, immunity is on the line during the wedding challenge, in addition to another one-pound penalty. One contestant desperately wants that immunity, and the win would allow them to use one-pound penalty against another contestant as payback. Finally, two couples face off in the elimination challenge and one couple will be sent home.
