The second ceremony of the episode began with Amber revealing that Barnett was having cold feet. While the former tank mechanic has been nothing but all-in for her engagement to the 28-year-old engineer, he's been a little overcome as the experiment progressed. But by the time the two make it down the aisle and Amber says, "I do," those fears have been washed away. Barnett happily takes the woman to be his wife, telling her that he "couldn't imagine a life without her." Cheers to the first couple to officially tie the knot!
