6 View Slideshow ⟶
The drama has been ratcheting up on Survivor: Caramoan over the past few weeks, and tonight’s episode promises to be no different. After Malcolm convinced Reynold to hand over his immunity idol last week (while holding on to his own secret idol) but still lost a member of his alliance when Andrea’s protective instincts kicked in, there’s no telling what shake-ups we’re in for tonight. What we can show you is what the reward challenge will be – and it looks to be a muddy mess! Click through for pics of the remaining Survivors getting down and dirty. Tune in for all the drama Wednesday at 8 p.m. on CBS.
