Cosmo gives Diego his idol

What happened
At the challenge the new white collar tribe (Diego, Rob, Night, Tyler) Lost immunity because of Tyler. Diego decided to talk to Cosmo during the challenge and told him that Diego was going to be voted out. At tribal council the vote was going to be Tyler. Diego knew this because he was the one to make the plan. At tribal when Simon asked for idols Diego stood up and asked Simon to bring Cosmo over. Cosmo came and gave Diego his idol and the votes went to Tyler but Diego played the idol to seem as if he was paranoid and thought he was going. Diego made this move because he didn't like Cosmo to have the idol so Diego needed to get rid of it quick.
