I'm going to hop on board with Vince...

Last week the Zapatera tribe had to decide between tribe “LOYALTY”, represented by Sarita and “COMPETITIVE STRENGTH”, represented by Stephanie…

”LOYALTY OF AN ALLIANCE VERSUS COMPETITIVE STRENGTH OF A TRIBE HAS THE CASTAWAYS QUESTIONING THEIR STRATEGY IN THE GAME,
ON "SURVIVOR: REDEMPTION ISLAND," WEDNESDAY, MARCH 23

As we saw, they chose “Loyalty” and Sarita , while Stephanie was voted out.

Stephanie will not go quietly and at this week’s duel, with two of the Zapatera present, Stephanie will air all the dirty laundry about Zapatera, including Sarita, who was selected over her.

”Stephanie : My strategy out here is to be brutally honest about Zapatera Tribe”.

”INFORMATION GATHERED BY WITNESSES ON REDEMPTION ISLAND LEAVES THE CASTAWAYS SECOND-GUESSING TRIBE LOYALTY,
ON "SURVIVOR: REDEMPTION ISLAND," WEDNESDAY, MARCH 30”

Sarita represents tribe loyalty, and after the RI Duel, the Zaps who attend “second guess” last weeks decision to go with “Loyalty” and keep Sarita over Stephanie.

David is this week’s boot decoy, set up by last week’s editing which featured tension between Sarita and David. This week’s previews include misdirection quotes, suggesting a David boot, from Julie, Steve and Sarita:

Julie:” David is bugging me.”
Steve : “ David's getting tough to stomach.”
Sarita : “He's a loose cannon.”

Last week Sarita was the boot decoy, she was high maintenance, and had dental issues. Nothing has really changed and this week she’s the logical choice if the Zap’s lose another challenge.

The Zaps will second guess themselves for the mistake made by choosing Sarita/Loyalty over Stephanie/Competitive Advantage, and will not make the same mistake again. They will keep David, the stronger competitor, who they realize was probably right when he voted for Sarita.

In the end, they will probably make the simple, logical choice… Sarita will be voted out.
