Bryan spoke about what it's like to have an older boy to look after. "You can kind of control a seven-year-old, a little bit, but you're not fooling a 13-year-old," he said. "But we love it. We feel honored that we're so blessed to be able to take him in."
Luke married his college girlfriend, Caroline, in December of 2006.
