Jeff Probst said in an interview that while Brandon was ranting, he was whispering into his mike for security to send back-up. Also, that shoulder massage he gave Brandon was not solely an attempt to relax him, but to give himself an edge if it did turn physical. He'd decided right away to hold Tribal right then and there, for if he didn't, Brandon would go back to the Favorites' camp and no good could come of that. All in all, Jeff handled it pretty well.
Did you ever wonder where the players go when they walk off into the darkness after being voted off? They meet with a psychologist. A psychologist was waiting for Brandon when he walked off in the direction Jeff pointed to.http://insidetv.ew.com/2013/03/14/survivor-caramoan-jeff-probst-brandon-hantz-meltdown/
