Sierra breaks it down in simple sentences that Debbie should be able to understand: Taj, Stephen, and J.T. are one unit. Erinn is obviously with them based on her vote for Tyson. At this point, Debbie lashes out, accusing Sierra of trying to cause them unnecessary worry about their alliance's stability. Does she have short-term memory loss issues or something? Is she forgetting that it was that worry that began this conversation in the first place? "I'm not giving you threats, I'm giving you facts," Sierra says calmly. LOL, she's half Debbie's age and twice as mature. Debbie flies off the handle and says she will not have a conversation that makes sense with Sierra today and puts up the hand. Sierra tries to point out that Debbie was the one who started this conversation in the first place, but Debbie just keeps saying she's done and showing Sierra the hand. Then she sobs and goes down to the river. I'll bet Board of Education meetings in her town are pretty similar to that exchange:

Board of Ed.: Principal Debbie, we're afraid that we cannot approve your proposal to take away math classes in favor of an additional gym period focusing on the ancient art of made-up bullshit called Chong Ran.

Debbie: (holds up a hand) Talk to the hand.

Board of Ed.: But you're the one who --

Debbie: I'M DONE!!! (sobs and goes down to the river)

While Sierra and Douche stand around the firepit for a period of Awkward Silence, Sierra interviews that Douche and Debbie tried to get their alliance back on track, and as soon as she expressed any sort of reluctance to get back in with them, they freaked out. Yep, that's pretty much what I saw, too. Sierra continues that the Jalapeño tribe is "brilliant" and used her to blindside Tyson. She'd rather play with the people who are doing this game right than two people who are morons. Too bad it's a little late in the game to figure that out, Sierra. But at least you managed to figure it out before Douche and Debbie.
