The final four group members must climb a 100-foot cliff, and Kareem faces his biggest fear. When they reach the top, they find out that they only have one match, and just one shot at having a fire. After creating a successful blaze, the tired team foregoes building a shelter, choosing to depend on luck to get through the night.
Adam, Jen, kareem and Zac all climb a rock to get to the top which is pretty scary. I know they had to build a shelter but didnt. But anyways there all doing a great job at surviving. I would never survive trust me.
I am not surprised that Kareem made it through that because he wants to survive and knows what that will take. He knows that he'll have to get up there in order to survive.
