 Justin loses 8 pounds, which means Arthur needs to lose 18 or more pounds to win immunity, but he only loses 16.The Black Team wins the weigh-in, meaning the red team had to send someone home (except Rulon, who wins immunity for having the highest weight loss percentage on the Red Team).Because the group dynamics were set up against him, they unanimously vote off the new member Arthur despite Bob & Jillian's desperate pleading for them not to do so.
