Being rewarded for greed. So stupid. She had a chance for $7,000. Knowing her family needed the money. And even after having horrible luck thru out the game. Decided to take the risk between $2 and $30,000. I knew it wasn't gonna be the 30k.
They did all spend time in the hotel when they recorded these shows. They did all have breakfast, lunch and dinner together. After the day's recordings of the three episodes, they all went for a drink in the hotel bar. So friendships did form.
