ON THE NEXT SURVIVOR
When the women's tribe decides they need a leader, Deena is elected, but some hope she will destroy herself.
The Reward Challenge becomes an opportunity for the male and female tribes to interact, leading the men to speculate about which women they may have a chance with.
Heidi, Shawna and Jenna bathe topless and promise they'll do the same in front of the men, if necessary, to secure their votes in the future.
A battle between young and old emerges in one of the tribes, leading to a critical decision for one Survivor caught in the middle.
