I thought one of Natalie's biggest moves went unnoticed... Yes, she got John out. Yes, she played the idol at the end to save Jaclyn and take her to the final 3. Yes, she got Alec out and kept Keith.

However, not mentioned was that in keeping Keith and getting Alec out, and using Keith to get John out... it was her that told him to keep his mouth shut. Nobody else worked with Keith. They were afraid he would talk too much in tribal council. In pulling off her big moves, Natalie not only did those moves, but she did them by using the person everyone else was scared to use because of his unpredictability. She coached him into what to say at tribal council so he wouldn't let the cat out of the bag and scare John into playing his immunity idol. Had Keith slipped up at all, it would have been over for Natalie if John had smelled anything coming and played his idol. So saving him, taking him in, and babysitting him into not opening his mouth to me, was the key move for her.
