15. The Sing-Off

For a choir sing-off, Mary has found housing for all of the competitors except one, and for good reason. He is rude, pushy and impatient. He winds up staying with the Jenkins. He tries everything he can to guarantee that his choir will win, including taking the judges to dinner and bringing in a professional gospel singer. The D.C. choir brings in Brenda, Tiffany and friends to sing with their choir, which gives them a unique, youthful sound. The competition ends in a tie, where both teams will represent the East Coast in the California semi-finals.
