<P> The second consequence unleashed a major twist on the House called the "BB Swap ." This resulted in Paul Abrahamian, runner - up from the previous season, entering the House as a full HouseGuest eligible to win by taking the place of an original HouseGuest . Shortly after entering Paul was given nine friendship bracelets which gave immunity from the first eviction . Paul was instructed to take one for himself and give the remaining eight friendship bracelets to the HouseGuests that did a good job tempting him . The remaining eight HouseGuests took part in a competition for safety which resulted in Cameron, Christmas, and Jillian being nominated for eviction . The three nominees were given the power to choose how their fate would be determined . The nominees had a choice of a competition or a house eviction vote . Only Cameron chose to have a competition; shortly after, the HouseGuests voted to evict Cameron from the House . </P> <P> The following temptation would be during the second Week 1 HoH competition . During the competition, a golden apple appeared that would guarantee safety for the person who grabbed it, but would eliminate the team from the competition . Josh took the temptation, eliminating his team from the HoH competition . In the Week 1 Power of Veto competition, the first HouseGuest to find a gold starfish and place it on their shelf would earn a Never - Not pass, meaning they cannot be a Have - Not for the rest of the season with the consequence of eliminating themselves from the competition . Raven took the temptation . </P> <P> Instead of permanent eviction, the first four evicted HouseGuests received a chance to return to the game . Unlike last season, this showdown was done in playoff style . They will participate in a 3 - Round - Battle in order to gain their spot back in the house . The first competition "Maze Race" will eliminate the bottom two finishers, permanently eliminating them from the game . Dominique and Jillian lost the competition to Cody and Cameron respectively; The second Competition between Cody and Cameron determined which first four evicted HouseGuest will be the last one standing and battle one of the HouseGuests in the house for a chance to get back to the house . If the evicted HouseGuest wins against the current HouseGuest, the remaining evictee will have a second chance to re-enter the house . However if the current HouseGuest defeats the returning evictee, no one will be returning to the house effectively blocking the Battle Back . The HouseGuests unanimously voted to chose Paul to battle Cody in the final competition . Cody chose "Maze Race" as the final competition . Cody won and re-entered the house on Day 30 . All three duels aired in a special episode on July 21 . </P> <Table> <Tr> <Th> Round #</Th> <Th> Winner (s) </Th> <Th> Loser (s) </Th> </Tr> <Tr> <Th> </Th> <Td> Cody, Cameron </Td> <Td> Dominique, Jillian </Td> </Tr> <Tr> <Th> </Th> <Td> Cody </Td> <Td> Cameron </Td> </Tr> <Tr> <Th> </Th> <Td> Cody </Td> <Td> Paul </Td> </Tr> </Table>
