I captured all the clips which had the survivor "potentially" during a challenge.
I then went through and got rid of all the caps which were from the first 2 challenges.
Here is what we have left...Brenda: (seems to be pulling a rope *and noticing the camera*)
Cochran: (looks to be holding on to something while in the water. Not really swimming)
Eddie w/Shamar and Hope: (Tossing a rope with ring on the end of it.)
Laura: (This one I wasn't positive it wasn't part of the 1st immunity but Laura is running)
Malcolm: (With diving mask on)
Matt: (swimming)
Phillip: (I have no idea what he is doing but he looks intense and he's covered with sand and sweat)
Shamar: (swimming)
Sherri: (with different "lifesaver" than the 1st reward challenge.)
Dependent upon how many "stages" a challenge has, it looks like we have 3 or 4 different challenges being shown.
Rope pulling, rope/ring tossing, swimming, "life-saver", sand/running.
