Just some Random Observations on some of the screen captures..

I originally thought that Eggs Jeff is holding out were Paint Filled Eggs for the castaways to break upon themselves to switch Tribes. However the CBS caption is ""Winner Winner, Chicken Dinner" - Jeff Probst during the fourth episode" So now I realize these Eggs are probably the Reward for the Second place tribe for the Ep4 Reward Challenge!

Edited to Add: Looked up this Reward Challenge in Ep3 of Cagayan "The winning tribe would receive three egg-laying hens and a rooster, while the second-place tribe would receive a dozen eggs."

I thought these 2 images looked like Mike Peeling and Roasting a Snake and the Sneak Preview reveals that is a Snake!

Kelly's forehead does not have a scar but if you zoom in I think she has a laceration just below the hairline to the right of the part in her hair.

In the Episode 4 Immunity Challenge Joe and Mike (everyone but Mike is on the Blue mat) start the ball portion before Joaquin arrives (Joaquin and someone else still climbing down the blocks in the background)

Joaquin joins Joe and Mike with Shirin and Dan/Lindsey sitting out in the background.
Looks like you have to negotiate 3 white balls into the 3 holes at the top.
If a ball falls into a hole it drops out of the purple chute on the bottom right.
Joe still has 2 balls on the holder on the bottom left and is lifting 1 ball.
Mike appears to be retrieving a ball that fell off? Looks like he still has 2 balls on the holder.
Joaquin may have completed 1 ball and he has another ball near the top.

Joaquin and Mike switch out but can't tell if Joe switches out...

Max tries after Joaquin

Kelly must be trying after Mike

CBS Caption: ""We're Finally Playing Some Survivor" - Jeff Probst reveals the reward during the fifth episode"

The Sandy Beach near the Reward above and the Rocks and Ocean behind White, Red, and Blue Collar below appears to be the Episode 5 Reward Challenge area as seen below.

Hmm, 3 stations but normally they swap tribes *BEFORE* the Reward Challenge. Perhaps they remove one station before the Reward Challenge begins or maybe this is a photo before the Dream Team tries it and they later reconfigure it for 2 Tribes.
