TENSIONS ARE HIGH AND ONE CASTAWAY REVEALS A POTENTIALLY GAME-CHANGING SECRET, ON "SURVIVOR: SOUTH PACIFIC," WEDNESDAY, OCT. 19

CHEAT TWEET: Feeling betrayed, a castaway reveals an important secret 2 his tribe. Good decision or bad? #Survivor Oct.19 @ 8pmET/PT http://bit.ly/nk0GG4

"Free Agent" – Feeling betrayed by their tribe, one castaway reveals a potentially game-changing secret, and appalled by the lack of loyalty within his tribe, another castaway threatens to leave the game. Meanwhile, on Redemption Island, Christine battles Elyse to try and win her fourth duel in a row and stay alive in the game, on SURVIVOR: SOUTH PACIFIC, Wednesday, Oct. 19 (8:00-9:00 PM, ET/PT) on the CBS Television Network.

We know from the preview that Ozzy is the free agent.

Feeling betrayed, a castaway reveals an important secret to his tribe = Does Ozzy tell everyone on this tribe that he has the HII as an offensive move? If he mentions that Keith knew all along, that would tick off Jim and others. Or could this clue be about Elysee and she spills some beans at RI? (the use of "their" doesn't help with gender)

Re 2nd part of clue: Ozzy wouldn't threaten to leave the game, would he? Although Cochran does say he's being a cry baby in the promo. Who are other potential people that would fit this clue? They use "he" so if we can rely on the promo monkeys it must be a male. They've been typically doing 1 clue about each tribe. Coach is big on loyalty but can't imagine him threatening to quit either....maybe Brandon if it's someone on that tribe?
