Maybe the shocker was that there will be two eliminated next week.
Jimmy Kimmel last night reported that "in the spirit of the charitable theme of the show, they showed kindness to the contestants and sent nobody home. Next week, they plan to eliminate two contestants and throw them in a volcano."
Actually, it happened in Season 2 when they found out about Corey Clark's criminal record. Because he had left, the votes didn't count that week and they didn't send anyone home.
