The reward challenge is an amalgam of past challenges.  Lauren wins the challenge, along with a new minivan and Les Sachs the dog.  She chooses Scott to come on a picnic with her.  While out, she makes her move on Scott.  He rejects her advances, saying he's gay. 

     The next morning, Scott meets up with Matt and they kill a squirrel.  Mary makes them bury it instead of cooking it. 

   The immunity challenge is a giant game of concentration.  Mary Lou wins her first immunity. 

    Mary becomes sick from the mushrooms.  Lauren considers severing ties with her.  Matt plans to vote out Lauren.  Despite Joe's black vote for Lauren, it's Mary who's voted out when her former friend Lauren turns on her.
