Tip: When it's you vs. Phillip Sheppard and Phillip is looking like the sane one, you've gone too far.

Brandon Hantz will have a very special meltdown on tonight's (March 13) Survivor Caramoan: Fans vs. Favorites Episode 5, "Persona Non Grata." According to the synopsis, "Out-of-control Brandon stuns his tribe mates when he reveals his secret desire to sabotage their camp."

It's no secret! He's already threatened to pee in the rice and beans, and in the promo for this week's ep we see him knocking chairs over and dumping all the rice. He's not well.

In a second promo (watch below), we see Brandon and Phillip yell insults at each other during what's apparently an immunity challenge. Then Jeff Probst — who has his hands on Brandon's shoulders, for some reason — says "We're having tribal council right now." So ... expect the "favorites" to vote out Brandon right then and there.
