Lily and Marshall try to sway the outcome because of a bet they made years ago over whether Ted and Robin's relationship will last. Meanwhile, Barney goes snooping for Marshall and Lily's sex tape, but winds up discovering that the couple has a secret box filled with bets on their friends' lives. Upon returning home, Robin admits that she doesn't love Ted and thinks they should remain friends, while Marshall decides it's for the best that Robin move out.
