Season 3 is Hard to Watch -- No Spoilers Please!

I just started watching Africa and I'm on Episode 1 (No spoilers Please!) I saw Diane just get voted off, and I just can't stand the foursome of Tom, Lex, Ethan, and Kim. Please, no spoilers, but someone please tell me these four don't win the game (without spoiling it for me please.) Like seriously, I NEED someone to tell me that one of these people don't do well in the game, but seriously, PLEASE PLEASE PLEASE tell me what happens without spoiling this season!
