"I was a little paranoid, so I must have had some idea," Jamie tells The Early Show co-anchor Julie Chen.
A little paranoid? He was driving everybody crazy trying to secure his spot in the game.
"I knew I was getting on everybody's nerves, but I think everybody out there is a little paranoid," he says. "If they're not, then you should be, because it's going to go crazy from here on out."
Even his friend Lydia Morales voted against him, which made the betrayal more hurtful.
"Lydia was my buddy," Jamie says. "She's a good person. She just didn't really know what to do when people come against her. I took care of her. I used to sleep by the fire with her and always keep her warm. I took care of her in the jungle. So when she did that, it hurt me a lot. I still hope she's doing great, and I hope she wins the million dollars, her or Judd."
Judd Sergeant maintained his alliance with Jamie even after winning the reward challenge when he bonded with Gary Hogeboom and Danni Boatwright.
"I didn't win a million dollars, but I made a million-dollar friend in Judd," Jamie says. "He always called me his little brother. His real little brother died when he was 24."
Describing his relationship with the tribe he says, "I was pretty close to the top five, except me and Cindy. I'm not really good at talking to people if I know I'm going to boot them. I look at Steph as a sister, Rafe and Judd as brothers, Lydia as a mother, and Cindy as an outside second-cousin."
And though he says Lydia told him a "million-dollar lie," when he asked her if he was going home, Jamie says he knew it was Rafe Judkins who stabbed him in the back.
"Stephenie and Rafe are the same person," Jamie says. "He doesn't do anything if she doesn't give here OK. Steph is controlling things way too much. Stephenie is the leader and she has Rafe as her lap dog."
But did Jamie realize his paranoia was irritating Rafe?
"I knew he was going crazy. I just needed a little bit of security with it," Jamie says. "I just wanted to know. You're going for a million dollars, so there's going to be paranoia when you're going for a million dollars. I get paranoid playing the lottery."
So if he could do it all over again, what would Jamie do differently?
"Maybe I'd stay more calm," he says. "It used to bug me so bad how Stephenie could stay calm. But she's already been there and has seen how people go crazy when the merge happens."
