Here are my notes on that section:

Jac and Jon talked game...in your mind who is in the F3...Missy and I had plan...us four, then Nat came in...Jac was going to give her game up for me...you have more of the jury votes, and I will fall on the sword, and Baylor said that too for Missy....
*Jon had a huge trust in Missy, my focus was, can I trust Missy? This seems too good to be true, didn’t think of Natalie...
*How was Jac going to do that?...when we got down to five, she was going to say, vote me out, I want to go before Baylor, because I want to be around the jury longer...

I got the impression that Missy and Jon were the two real bonded, committed in the alliance. They each brought their partners in...Jaclyn and Baylor. I think this probably happened pretty early post merge, before the Jeremy boot. Then, Jon and Missy trusted it, but it was Baylor that went astray with Natalie. As he says, he felt sure of Missy, and discounted Natalie and Baylor, while Jaclyn was suspicious.
