TOM TRIUMPHS
The Challenge started with a flurry as the Final Four hurried into the field of tires. Tom took the early lead with Katie falling behind. It was a close competition as the castaways unlocked the various hatches and climbed up the tower. With Tom clearly ahead, Jennifer had difficulty using her grappling hook, yielding second place to Ian. Once again, the Challenge came down to Ian and Tom.

In the final stage, both Ian and Tom quickly descended the flying fox and splashed into the water. After both had collected their lock boxes and returned to shore, it was down to who could figure out the combination and free their flag first. A delighted Tom finally snapped open his padlock and raised his flag, seizing this crucial Immunity.

DIFFICULT DECISIONS
After winning the Immunity Challenge, Tom regretfully explained to Jennifer that he intended to honor his alliance with Ian and vote her off. As it was clear that Ian and Katie would follow suit, Jennifer tearfully understood. After Ian revealed that Tom's decision would've been a hard one for him to make, Tom was suddenly alarmed that Ian had planned to betray him. After Jennifer confirmed that to be true, Tom held Ian up to the fire. All Tom could say was, "Makes me think."
